309 or 375 JDJ
« on: January 31, 2003, 06:23:41 AM »
If someone was in the mood for either a 309 or 375 JDJ and was intending to hunt whitetail, maybe elk, black bear, or even a moose,  :-) which would be preferable?  Also, how is the recoil for both out of say a 12" barrell?  Is one easier or harder than the other to load for?   THanks

I have a 375JDJ in 14" with a muzzel brake.  Have never shot the 309.  I can tell you, it would likely be a handful without a brake or with a shorter barrel.  I really enjoy this caliber, but I don't think I'd want it in a shorter version just from the standpoint of muzzel control when I pull the trigger.  Lose control of the muzzel and your accurracy goes out the window.

One of my shooting buddies hunts up here in Alaska solely with a contender, and primarily with a 309 and 375 JDJ.  From his experience, the 309 is a poor choice for moose, and marginal for larger black bears.  

You are also sacrificing 100 fps by going to a 12" barrel, and those rounds need all the speed they can get for consistant bullet exspansion.  

Both rounds are accurate, and preduce a good deal of recoil, the 375 definately comes back in your hand.  

My personal suggestion would be a 6.5 JDJ for white tails, and a 375 for the big stuff.

I would go with the 375JDJ for the big stuff. Don't forget about the 338JDJ of the 358JDJ.

309 JDJ VS 375 JDJ

I SHOOT A 309 JDJ CONTENDER WITH A 10" BBL AND I DONT FIND THE RECOIL UNPLEASANT.THIS IS A VERY ACCURATE CALIBER AS IS THE 375 JDJ.THE 30 CALIBER BULLET HAS A WIDE SELECTION OF CHOICES TO MAKE IT AN APPROPRIATE CHOICE FOR MOST ANY GAME YOU WISH TO HUNT.I AM HUNTING BOAR TOMORROW WITH MY 309.I WILL BE USING A 165 GR BULLET, FOR DEER I WOULD CHOOSE A 150 GR BULLET.I PERSONALLY THINK A 243 WIN IS NOT AN APPROPRIATE DEER CARTRIDGE,BUT EACH YEAR THOUSANDS OF DEER ARE PUT IN THE FREEZER WITH THIS AND SOMETIMES EVEN SMALLER CALIBERS SUCH AS 22-250,222,OR 223.PERSONAL PREFERENCE IS WHAT MAKES THE SHOOTING SPORT SO GREAT.JUST CAUSE I LIKE IT DONT MEAN YOU WILL.DO YOUR HOMEWORK,THEN CHOOSE WHAT YOU WANT TO SHOOT GOOD LUCK,JIM :D

Yeah, and if I didn't have a 308 Encore, you would NOT have a 309 to shoot! HA! I hope you enjoy it and bang that pig. I got mine with a 45-70. Good luck.  I'm looking to send my newest TC 10" 444 Marlin out for a 'brake job' and a TSOB.  I thnk I'm gonna call my next hunt 'Thunder in the woods'.

Go for the 375 if you're really considering Elk and Moose. Get it braked though. I had a 358JDJ that would not keep a scope on until I sent it back. They kick real hard with heavy loads. The recoil on a 309 is very manageable. I shoot an Encore '06 and a 308winchesster without a brake, and the '06 starts to bite with heavy loaded 180 and 200's, but they are both sub-1 inch guns. I have a Leupold 2X on the 375JDJ and it is extremely accurate. 3 shots at 175yds with a 185gr Speer GrandSlam all landed with 4" of each other in my 6X6's shoulder (I shoot Elk till they drop) and I had complete pass-through penetration with no bullet recover. I have two other Elk with 35Rem and 1 with a Heavy loaded 45LC. I believe 'IMHO' Elk demand that kind of power and penetration when hand-gunning. We're at an extreme velocity deficit, even with teh 309. I'm planning on trying my '06 this year, but I have alot more expansion tests to do before October. I htnk these velocities will greatly reduce my useable range of the Nosler-partition. I'd really like to consider a 180 or 200 gr Balistic tip cuz I haven't experienced explosive expansion, but I still no that Elk are tough. I also know a wounded Elk can travel far and fast. I would not hesitate a 309 on White-tail or mulies. I have taken some and they work well. Good luck. Back to the bench.

If you are going to go for the heavy "varmints", you'll need the 375JDJ out of the two.   I have both the 309 and 375 (and 257) JDJ's, all 14" - the 309 just isn't enough for something the size of a trophy moose in my book, and I've run into some grizzlies up close and personal that the 309 might just "T" off!   My 375 is very accurate, and with the SSK Arrestor MB is also very managable.    I mostly shoot 270 gr. pills in it, but also some 300 gr.

Here's my 375...

Markc, Given the BIG game you're aiming for, I'm going to vote w/ the 375 JDJ crowd, here.  :grin: I'll admit I've never hunted moose nor elk, but I bought my 375 JDJ a few years ago hoping that one day I would. The 309 JDJ is no doubt a fine round, but I think when hunting moose/elk w/ it, you'd have so many limitations  to live w/ (compared to the 375 JDJ), that the hunt would be quite restricted. Anyway, that's the beauty of the Contender--you can have different barrels for different applications :-)  Of course, shooting different barrels is also a big part of the fun of Contenders! Get the 375 JDJ now and then get the 309 JDJ later.  :P My 375 JDJ has the SSK brake on it which makes it quite manageable. Can't say what it would be like w/o the brake, other than a lot more recoil.  :eek: I don't think the 309 JDJ needs a brake. Gary T.

I have both the .309 and the .375 JDJ barrels.  Based on my experience, I recommend the following to you for your consideration:

1) Consider getting a 14" barrel.  This length actually balances better for me.

2) The .375 is the easier of the two to form cases.  Just run a .444 case through the sizing die and you are done.  The .309 requires a bit more work.

3) The .375 is a better choice for the large game.  I took a Hartebeest at 300 yards as well as several whitetails with my .309 at this distance.  However, if you need extra stopping power; it's hard to beat a 300 grain .375" diameter bullet.

4) The .309 does shoot flatter than the .375, but Itook my Zebra at over 200 yards with my .375.  I have also shot groundhogs out past 200 yards with it.  So the accuracy is there. If you know the load's trajectory well, hits out to 300 yards are not impossible.
Hope this helps your decision making.

:D  You said that you have a 309 JDJ in 10"? What do you compare the recoil to? What about muzzle blast? Any information or recomendation that you can provide will be appreciated. I have 30-30 10" that might want to get it rechamber to 309. Thanks
