cast load for 300 Sav?

[c mac]

I know. This should be on the reloading page. I already tried that with no response. I've got a box of cast 165 gr moly coated bulletts from Magnus bulletts. Any ideas for a load? Can they be pushed a little faster with the moly? these are not gas checked. They'll be shot out of my old Model 99.

I would try 16-18 grains of IMR#4198 with that flat base bullet.Use Dacron,if you have any experience with it.

thanks for the reply. Tell me more about this load. Dacron? How many FPS? Also, know anything about the moly?

Before you shoot those moly-coated bullets, I'd check into what they're going to do (if anything) to your rifle's bore.

Quite a while ago, I read something "negative" about moly-coated bullets, but I can't remember what it was that moly-coated bullets do to a rifle's bore, but it is "something".  Check with your gunsmith, it might save you a some problems.

Ron T:  I remember reading something about that - I think it was in one of Rick Jamison's columns but I think it was something about a moly buildup in the bore.  Also read that moly doesn't really do anything for accuracy or velocity increases as was predicted.  

c mac - the 300 Savage is one of those old sweethearts of a cartridge, as is the rifle they are shot from.  I personally would not advocate pushing them to velocities beyond what I would normally push a cast bullet in that caliber and there should be adequate loading data available for that cartridge in most reloading manuals.  

I know that with 150 gn jackets you can push the 300 Savage to 2600'/sec and with 180s to 2300 (plus or minus a bit for both bullets) but I believe the cast loads are down around the upper 'teens' and wouldn't try pushing them beyond that.  Just my 2 cents worth.  Mikey.[/i]

Righttttttttttttt.... Mikey, it was about "moly build-up in the bore"… and, now… I remember that, as you remembered, the moly coating didn’t increase either velocity or accuracy.  Therefore, why use it?  THAT was the “negative” I was talking about in my previous post.

I noticed my old reloading manual recommends “gas checks” on cast bullets for the .300 Savage cartridge, but doesn’t offer any loads for a 165 grain bullet.  It keeps the muzzle velocities down to about 2,000 fps or less.  You don’t want to “lead-the-bore” by using too high a velocity with a cast lead bullet.  It indicates an “accuracy load” for the 173 grain cast bullet (bullet #311291 with a gas check) using 22.0 grain of IMR4227 which yields 1868 fps.

My hunting handload using 150 grain Nosler Ballistic Tip bullets for my Model 99 in .300 Savage chronographs at an average of 2680 fps using a maximum load (41.5 grains) of IMR4895, Winchester cartridge cases and Winchester standard large rifle primers… and averages .75-inches for 3 shot groups @ 100 yards.  This load is a “MAXIMUM LOAD”, so use the “standard reloader’s procedure” and reduce your initial load 10%, then “work up” to your rifle’s maximum load not to exceed 41.5 grains of IMR4895.

c mac,
I know nothing about Moly.
I do that the Lyman 31141GC bullet shoots very well in my "99.
it weighs 176 grains,with a hardness of BHN#9,and is .309 diameter.
I use a 3/8"x3/8" square cut from a 1/4" sheet of Dacron.
At 50 yards,with IMR #4198 powder:
16.0 grs-es 5/8"
18.0---------3/4"
19.0---------7/8"
20.0---------5/8"
21.0---------3/4" @ 1697 FPS
21.0----------2' @ 100 yds
22.0----------5/8" @ 1738 FPS
I just bought the Savage '99 last Fall,and started load developement last month.We're having a lousey Spring this year in NY.

Please explain to me about the dacron in detail. Iv'e never heard of that. I live in Schoharie Co. on top of a mountain, Cotton Hill in Middleburgh. I know what you mean about the weather. I've got the wood stove going again tonight. Thanks again.

c mac,
I have been using Dacron successfully for about 50 years(as soon as it was made available),without any problems.
But,recently,Dacron has become controversial,so check with the anti Dacron Crowd,before you try using it,yourself.
I have tried grabbing a 'pinch'from a big ball,but it is a lot easier,and more consistant for the same sized individual wad,to cut the wad from a roll.
Rolls come in as least two thicknesses. I just measured mine,it's 1/2 inch thick.
I have a plastic grid,marked with lines spaced 1/2"apart. I use this to mark off strips of the Dacron on a foot long sheet. As I need the filler,I cut a 1/2" x 1/2" strip from the sheet. Then I lop off 1/2" cubes to place into the case mouth.
I center the Dacron cube over the case mouth,and push it into the case with a blunt pencil point. I'm careful to push the center of the cube down,so the filler has equal pressure on all sides of the inner case wall. This will tend to keep the filler from shifting.
Then,I reverse the pencil and push the wad onto the surface of the powder. This is a little tricky. You don't want to tamp the filler down,just let it rest on the surface.
Some people will place the filler in the case mouth and push it down when you seat the bullet. I've tried this,but for me,it destroys the accuracy of the load. If you try this,and have any success,please post it here.
The size of the individual filler can be controlled by lopping off different lengths of the 1'2" x 1/2" strips.
Good luck,
Frank
