CZ .375 H&H 550 american Safari Magnum (load data)

[duckey]

So after owning this gun since 2008, I have only shot it 13 times with factory loads. I recently bought 50 pieces or NEW Hornady brass from Zman for a great price! I also have Federal #215 Large magnum rifle primers and 2 lbs of RL-15. Been looking for a light weight bullet and found a Speer 235 gr Semi-Spitzer on Midway's site for $19.95 per 50. I am looking to shoot this a lot more often without breaking the bank or bruising up my shoulder to badly. I have found load data on Alliant's site calling for 78 gr of RL-15 behind a 235 gr SP that will push it 2920 FPS. One review on Midway using RL-15 (but didn't specify quantity) chronographed this load at 2750 FPS. Lots of good reviews for this 235 gr Semi-Spitzer, from 100 yards to several hundred for deer, and plains game....which is what I am looking for (Speer lists this bullet as a mid range bullet). I just want to shoot this gun more and become more familiar with it. Would also like to use it for whitetail and moose (with a different load) if I am ever lucky enough to draw a resident tag in Maine. I recently installed a scope on it with QD Warren rings (check out my photo album). So in closing if anyone has any other load data or suggestions that wants to share please post up. I am all geared up with a set of RCBS FL dies (2 die set) and a nice Lee Classic press to handle magnum cases.

I am pushing a .269gr. boolit from a lyman mold #375296 with IMR4198 this is a pretty low recoil load for the .375 H&H Mag. I do not see why this load would not take your moose at 200yards. Lymans manual says to size it .376 but I am getting much better results sizing them .377

The 235 gr would probably do the job on a moose. I looked into casting my own for this gun but would be more costly...mould, gas checks, sizer, expander die etc. It is my goal as a reloader to cast for everything I shoot, I am about half way there now. For now I'll by factory bullets and as I have done for the past couple years, slowly buy reloading and casting equipment as the budget allows.

duckey, I have used reduced loads for deer in the past utilizing the Sierra 250 SBT. Yes you do tend to shoot more when itsfun to do so.
I took the loads from Ken Waters Handloader #203 Feb/Mar 2000 and yes I will share, but, these are not with RL-15.
235gr Speer semispitzer IMR4895 65.0 gr. 2463 fps 3165 ft/lbs
Varget 63.0 gr. 2482 fps 3214 ft/lbs
FWIW My load with the Sierra 250 SBT was; IMR 4064 62.0gr @ 2454fps w/3342 ft/lbs and very accurate out of my Model 70 Alaskan
Hopes this helps

The 375 performs extremely well with cast PP--------------fun as well-----------when you get a bit further along give it a try

Thanks will read up on it. I bought a box of Sierra Hot Cor 235 grn Semi-Spitzer bullets from Midway last night. They do not have a canular on them and was wondering if it is OK to roll crimp them...is it nessasary? Some of the reviews on this bullet would have prefered a canular to roll crimp thinking that the recoil may drive the bullet tip down into the case but the reviewers never commented onthat ever happeing, all reviews were positive.....?

If there is no crimp groove- don't try to roll crimp. It won't work, especially on a Jbullet. Matter of fact it may even loosen the neck tension. Just good neck tension to begin with should do it. If desired, a small additional "crimp" can be added to a smooth-sided Jbullet already seated using a Lee FCD.

[dave roelle]

load one using standard die settings with just neck tension----then get your inertial puller and see what it takes to move the bullet in the case------betcha it takes one heckova whack and perhaps several--------------i've loaded 270 grain sierra's and 300 grain speers---no crimp with full house loads and never moved a bullet :)

The 375 is one of my favorite rifles to carry

I realize you're looking at casting for the 375 later, but hoping to be able to shoot it more often, so I thought I'd mention looking at some of the Mil-Surp powders still available.
I've been using WC872 (available from GIBRASS for as little as $40 per 8 lb keg) with the H&H. Filled to slight compression (use safe practices of working up loads for your own firearm), I use up to 90 grains with a 270 grain gas-checked cast bullet. Total cost (primer, powder, and gas check) is around 15 cents per round, plus my investment in alloy (which is minimal).
Velocities chrono slightly over 2300 fps and groups run 1.5-2 MOA easily.

Thanks for all the suggestions/ideas.
