does anyone have any loads worked up using IMR 4350 and a 100 gr. bullet?

2ndtimer · Feb 9, 2014

I have used from 39.0 gr to 42.0 gr of IMR-4350 with 95 and 100 gr bullets from Nosler, Hornady and Remington. A lot of people try 40.0 gr and go no further, as it usually shoots pretty well in a lot of rifles.

Hodgdons online data lists a starting load of 38.5 grains and a max of 42.0 grains of IMR 4350.

thanks guys. I have never used IMR 4350 before, is it a ball, flake or extruded.

IMR-4350 is a large grain extruded powder that doesnt meter very well. I trickle and weigh all my charges with that powder and similar powders, i.e. 4831, Reloder 19 and 22, Vihtavuori N-165, and others.

Does your powder have to be imr4350? Most of my loads are with H4350.

40 grains of IMR-4350 with a 100 gr. bullet has been my standard load for years. Nearly one hole groups out of my CVA 'kit' Mauser 98.

hodgdon book shows min. at 39.0grs to max of 43.0grs. Did you try the 39.0 load.

Pokerace. My 2013 hodgdon manual shows 37gr. start to a 40 gr. max. 38.2 is on the lower end, but shoots good in my gun!

Quite a few years ago, I picked up a Remington Mod. 788 in .243, a buddy had a nice pre-'64 Winchester Mod. 70 in the same caliber, and gave me his "pet" load, 100 gr. bullet in front of 43.5 gr. of 4350, he said it was easy to remember the charge...
It worked fine in his rifle, but in mine, I had to pound the bolt open with a plastic dead blow hammer.
And, I had to have the rifle checked out before firing it again, this time 40 Gr's. worked fine...
