.375 Ruger, 300gr TSX and IMR4350

[Viral_SIGness]

Its the fastest listed powder for a Nosler 300gr, so I decided to try it with the Barnes TSX. Eve at 78 grains, I cant get the bullet seated to 3.30, it keeps pushing back out. 3.345 is the shortest I can get it to stay. Funny though, because you can still hear the powder shake inside. Yet, while seating, you hear it crunch.

So I'm wondering if anyone else has tried it.

Have you looked at Barnes data? Barnes bullets being Monolithic, have different load data. They have free online load data.

Yes, but they didn't list IMR4350. I was start at the bottom because Barnes bullets produce higher pressures. Barnes shows AA 2700 and Win 760 as the fastest powders, but with things as they are, you work with what you have on hand lol

I have RL15 and Varget, but Nosler lists 4350 as good for the 375 Ruger. So I at least wanted to try it.

I understand. The Barnes are longer than the noslers. It might be part of the reason they only list faster burning and ball powders.
The only thing might be to reduce the charge and use a drop tube.

I tried running two drop tube on my funnel. Lol I'll probably just stick to RL15 for the Barnes. 69 grains was 2409 average from my 20" barrel. Going to test it from the 23" tomorrow.
