.375 H&H and IMR 4350

[Rob404]

Rob, that's some fantastic shooting. BTW, I once almost bought a Withworth Express, and your grouping makes me regret the "almost" part. Here's my .375 H&H Flanged with RL-15 and a 270-gr Speer BTSP. Again, dying to try the Win 760.

Thats a five shot group WOW a little spread between the groups but I'd take it

Hodgdon 414, is the same as W760, I use H414 in my 375 H H with great results.

Close only counts in horse shoes, so I can't help.
I use 250TTSX and H4895
Hope someone can help you out.

Horse shoes and hand grenades.

Care to share what bullet and grains? How are your groups?

Horse shoes and hand grenades.

And 60, 81mm and 4.2" mortars as well as 105, 155 & 175mm & 8" guns- all bring an order of civility to an otherwise barbaric infantry brawl.

I really like loads that work well and can be loaded right to the base of the bullet... but not compressed. 4350, either type, can be loaded in the 375 HH up to the base of either the 270 or 300 gr seated to a normal depth, be at 100% load density and do well. I think my 375 HH data for accuracy and SD of velocity very slightly favors Varget over 4350, but not by a lot. I also tried Reloader 19, it did well and was comparable to 4350. I shoot a bunch of 4895 type pull down powder for range time and paper and that also does fine in the 375 HH. Loading the 375 with normal bullets and loads is kind of like loading for the 30-06- matter of fact there may be some scaling effect in play comparing the internal ballistics of both cartridges.

I do as well. Sub moa with 270 and 300 gr A-Frames. Even better w 350 gr Woodleigh core welds.

I think you left out both napalm and thermonuclear warheads.

IMR 4350 works well in the 375 HH but win760 may give you more vel. I also use re15
And 260 gr Nosler part. With good results.
