Author Topic: Need 375h&h loading tips (Read 448 times)

Are there any special considerations for handloading 375H&H? For example, different procedure because of the belt on the case? Crimping?

Thanks.

I don't do anything different than with other cartridges. I back the dies off a bit but not so much so that they won't chamber easily after resizing, but I do this with all of my dies. I don't crimp.

I've had good accuracy with the Speer 235 grain bullet and am thinking of trying it on deer if I ever get around to it.

Picked up a bunch of Hornady 270 grain bullets at Walmart for $9.00 a box and they shoot decently also.

So far I've just punched holes in paper with mine.

I make sure to check cases for overall length and trim them back when they grow. The long tapered case of the 375H&H is prone to stretching. All my 375H&H ammuntion is neck-sized using a Lee collet die and checked for chambering before a hunt. Personally I like to crimp the projectiles.

Hi: Just treat the big belted case like you would a regular rimless case. You can F.L. resize for trouble free hunting ammo , partial F.L. resize for your rifle alone so the shoulder is not being set back , thus getting longer case life , or neck size only your own fired cases.
It's not any different I found than another case...

Also I used to crimp , but no longer do , accuracy will improve right away if you don't.
If you shoot for practice in hot weather , you can use standard primers. My hunting ammo in cold weather gets mag primers tho.
As for powder , the big 375 can use a wide variety. I have used IMR's 3031 , 4064 and 4350. Also H4895 and 4350.
My best accuray was with H4350 and Hornady 270 gr R.N. bullets from a Win M70 (post-64)

Watch your O.A.L. as I found out I could seat the bullets way out - but would not function through the magazine , have to compromise on that one.

Let us know how you made out. More questions? Ask away...

Regards,
Bob

This is very helpful. Thanks. I'm starting with Speer 235s & 285s, and with Reloder 15.
