wanted to give range report on a new rifle. Rebarreled savage 110 using douglas blank, 4x scope with syn. stock. 1st load was a fire-form cast bullet load that gave 2" groups @ 50 yds. 2nd load was with hornady 220gr fn bullet 1/2" group @ 50yds. 3rd group was with speer 235gr. and 4895 shot 1/2" @ 100 yds. Funny how things work out, as I had wanted to do a .376 steyr first--got dies, brass, reamer and then buddy comes by with a new .375/.338 reamer and new set of rcbs dies so what's a guy gonna do --Hell make one. Man o Man am I happy!! and he is happy too, I let him shoot about 10 rds. Waiting for another 110 action and he will have his, and he can quit pestering me. Will work up some cast bullet loads in future for next deer season. Wanted to share my good fortune, Bill439

bill439,

I am considering a 375 but not sure which one, H&H, Hawk/Scovill, or the 375/458.

Any chance you might get those loads over a chronograph?

I'd be interested in seeing the velocities you got, and how they compare against the other two I mentioned.

Thanks

Strawhat, the loads that I shot were no where near max and I did not chronograph them as I was just forming brass and having a good tiime. I do believe tho that the 220FN hornady will be a very good load for deer. This was a mild load of H4895 and I would think vel would be somewhere around 2200-2300fps. I can tell you that the 375/338 is the same as 375/458 (same parent case) and the others you have listed are based on 06 brass. All of the cartridges are good ones, I guess the question really is ---is what rifle action do you have to build on? the 06 and 338, 458, are all std. length and are easy to come by. The Great .375 H & H requires a mag. length action and those are not so common. The new Ruger .375 is also supposed to be std. length. I can only tell you that I am totally happy with the 375 taylor that I have, and would't trade for a full-length H & H. I will build that .375 steyr later and will more than likely use a std. length action, or hey maybe on a Siamese action as the length and size may be very close to the 8x52.(I remembered that you have a Siamese that you are thinking of coverting) Strawhat, I haaven't forgotten about the 30-30 AI info you asked for, maybe this will help---I haven't loaded for the AI in 20 or more years, but I remember not being able to get to the level that was listed in Ackley's book. I stopped at a full 2 grains under what he had listed. The gun I have is a savage 24 30-30/ 20ga and I did the conversion to improve extraction and case life. It did do those things but I don't think I improved any as far a power or velocity goes. Wish you luck, Bill439

I'm new to your project. I'm familiar (by reading only) with the 376 Steyr, but not what you're doing. Did you neck up a 338 Win Mag case? Is that what I'm reading?

I'm in the process of building a Savage 110 in 338WM at this time, but the thought of this case with a 358 or 375 bullet did cross my mind as well.

Tell me more about your build if you can. Or point me to the link if this was covered in another thread, please. Interesting project. What do you plan to hunt with it?

handirifle · « **Reply #4 on:** March 03, 2008, 07:24:05 PM »

One more question. Why not just build a 375 Ruger? Just curious, not claiming one's better than the other.

bill439 · « **Reply #5 on:** March 05, 2008, 11:42:56 AM »

Handirifle, this is how I ended up with what I have. 1. I had been looking for suitable actions for .375 H & H --no luck 2. Had always liked the .338 necked up to .375 know as .375 chatfield/taylor. but it not being a factory cartridge made me back off and think new thoughts. Along comes the .376 Steyr so I get dies, reamer, and start to ponder what action should I use for this cartridge? Well I chose the Savage 110 because I had one already in 7mag. and it would require no mag or bolt changes. Ok looking good at this point--then my buddy comes by with a new chambering reamer and die set for ---youi guessed it---.375 Taylor. Well I always wanted one and now I had everything I needed to build one, so the rest is history. Yes I will build a .376 steyr later, but right now I am happy with the Taylor. Oh and by the way if I ever change my mind about the Taylor I can just set bbl. back and rechamber to .375 Ruger. So far I don't think that will ever happen. What do I think I will use the rifle for? Well in this country- anything!! What I hope to do is to develop some cast bullet loads for deer and pig. I hope to carry this rifle a lot, and I don"t think I'll have to ask myself if I have enough gun. The Savage 110 that I used required no changes other than the barrel work. Feeds and ejects perfectly, and I would expect same it in .338wm. You said you had thought about the .35 on the .338 case, well you're discribing the .358 Norma Mag. a very fine cartridge indeed. Good luck on your .338

deltecs · « **Reply #6 on:** March 05, 2008, 11:58:34 AM »

Why would you have to set the barrel back for a re chamber to .375 Ruger? The bolt face is the same, the Ruger is a larger diameter case with the shoulder farther forward than the Tayor, so I would think only a re chamber would be necessary. Please elucidate me.

I've learned a lot form this post. This 338 project rifle is my first endeavor into the magnum world and even though I haven;t even shot it yet I'm looking forward to it more and more. I have limited experience shooting the mags but found I don't fear them like some seem to do. Being a reloader helps.

I knew nothing about the Taylor round and now, thanks to you, know something about the 358 Norma. I guess it was only logical someone would open the cases up to experiment. Looking at the Midwayusa listings, I see the 358 Norma, is darn close to the 375 Ruger, with a 250gr bullet at 2850 and the Ruger with a 270gr bullet at 2840. I imagine your taylor round will all but match the 375 Rugers performance. It should at least meet the Norma's performance, most likely exceeding it.

I would not be suprised to see the Taylor hit 2800 with a 270gr bullet. Quite impressive to my thinking. And as far as feeling undergunned? No way, not in this country or many others. Looks to me like you're squarely in the home territory of the 375 H&H.

Cast loads with a 250-275gr at 2000 or so ought to really hammer deer or pigs. Good luck with the cast loads.

Living in CA and the upcoming lead bullet ban (goes in effect July 1, 08) it really limits me to expensive Barnes bullets. Not sure how well they'll do in reduced loads. I'm thinking of loading it to 338-06 levels for deer and full house for bigger game.

response to deltecs, as I didn't have the chamber specs on the new Ruger .375, I thought
the belt may present a problem, if the belt diameter is smaller than the head diameter of the Ruger, then I have been Elucidated. Thanks, bill439

bill439 · « **Reply #9 on:** March 06, 2008, 10:48:04 AM »

response to Handirifle, The .375 chatfield/taylor and .358 norma has been around for at least 35-40 yrs. I wish Ruger would have made the Taylor a factory cartridge instead of going to their own thing, but hey everyone has to get thier name on something!!. Yea I know already that some will say the ruger did away with the belt and that is good, and it has more power and it looks pertty and its new and better and ect ect. But for me I already had 100 new .338 factory brass, new reamer, new dies so not a hard problem for me to solve. I guess by now someone has already built rifles on the new Ruger cartridge necked up and down and singing songs about how wonderful they are, and you know, they just may be wonderful. I am happy with this old one!!!! I regret to hear about the restriction in your state on the use of types of bullet material. I hope this wil be a small cog that will be removed in the near future. Wishing you well, bill439

From what specs I can find, the base diameter is .532, the same as the diameter on the belt. However, after some more thought, the belt diameter is constant for the width. I don't know if the Ruger has the same diameter as the belt does right at the muzzle end of the belt. Since the case tapers somewhat, it may be a bit less right at this spot, so then you would have to turn the barrel back and re chamber. I've tried to get the actual specs on the case from the net with no succuss. Maybe a good gunsmith may have this info and pass it along. You could also re chamber for the .375 Dakota with some bolt face mods and do the same thing. Both it and the Ruger have nearly identical case capacities. However, I think it would be a waste of money, since the .375 Taylor only has slightly less capacity and the game wouldn't be able to tell the difference.

CapoWard · « **Reply #11 on:** March 09, 2008, 05:20:33 PM »

You should have your chamber sized by a competent gunsmith to measure the belt diameter area so that you can assure that the 375 Ruger chamber reamer is not smaller than your chamber in the same area or you could perhaps fire form a small belt area on the brass with hot loads otherwise you should have no issues.

I measured a few of each unfired and fired cases to see what one might expect; Point 1 (P1) will be the edge of belt at rim side and Point 2 (P2) will be the edge of belt at shoulder side, the Ruger cases were measured at same points

Unfired Cases:
Hornady 375 Ruger: P1=0.530” and P2=0.530”
Remington 350 RemMag belted: P1=0.525” and P2=0.526”
Weatherby 257 WeaMag belted: P1=0.530” and P2= 0.529”
Winchester 264 WinMag belted: P1=0.531” and P2=0.530”

Fired Cases:
Hornady 375 Ruger: P1=0.530” and P2=0.533”
Remington 350 RemMag belted: P1=0.525” and P1=0.526”
Weatherby 257 WeaMag belted: P1=0.530” and P2=0.532”
Winchester 264 WinMag P1=0.531” and P2=0.533”

Hope this doesn’t muddy up the waters!

Cheers,
Jim

From your dimension research, it looks promising that the barrel would not have to be turned back to re chamber for the .375 Ruger. I agree though that I'd first have the smith check the chamber and compare dimensions to be sure.

bill439 · « **Reply #13 on:** March 10, 2008, 06:39:37 AM »

Back from the range, shot .375 taylor yesterday with 2 different cast bullet loads. Both shot 11/2" groups to the same point of aim at 50 yds. This was using the 264 gr. lyman bullet and Herco and Unique powders. Looks promising for both loads. Thanks to jim posing the questio;n and greg measur;ing brass, taking the taylor to the .375 Ruger may be even eaiser than I thought. Thanks for everyones imput, Bill439

Probably, but unless you really want the .375 Ruger, there isn't any need to re chamber. For the 3-7 gr more powder in the Ruger, there isn't any real ballistics change. The game certainly couldn't tell the difference and neither could the shooter at any range. The cost of the re chamber would be the only difference in the end.

bill439 · « **Reply #15 on:** March 11, 2008, 11:23:39 AM »

greg, I have no plans to rechamper to the Ruger, but nice to know it can be done. What I am working on at this time is to find a cast bullet load that will be on at 50yds when poa for jacketed loads are on at 100. Still have lots of work to do on this rifle, so far it is shooting extremly good. Get the cast bullet thing done and I am ready for next deer season. Thankls to everyone, bill439

As I mentioned earlier, I'm building a 338WM, your parent case, and am curious about the cast bullet load. I'm sure it would work as well in the 338.

Any info you can share on the bullet, velocity etc, I'd appreciate.

bill439 · « **Reply #17 on:** March 25, 2008, 06:46:25 AM »

Handirifle, sorry for taking so long to reply, the 2 loads i have tried so far were 16.0 grs.and 18.5 grs. of herco and lyman 375449 bullet using ww and 50/50 lube. This bullet with gas chek weighs 265grs. Both of the loads shoot 41/2 to 5 " low @ 50 yds. accuracy is 1.5" at 50 yds. I think I will go to a different powder like 4198 or 4227. If I can get the cast loads to shoot to the poa @ 50 yds. I will be done. hope any of this info will help. Hope to be able to do some more loading and expermenting in the near future, Bill 439

I may have missed it somewhere, but what is the parent case for the .375 Taylor?

.375-.338 Win. It is the .338 Win case necked up to .375 bore with little change.

What are the ballistics in comparison to a 35 Whelen? I don't have it in my Lyman's reloading book.

The ballistics would be almost identical to the .375 H&H.
