155gn in 30br

[vixenfoe]

Hi there,
I have a 1-14 to 1-15 twist 30br based on a Remington switch barrel and want to try some 155 gn projectiles.
Is anyone shooting these at the moment?
I am chasing a load to start with with H4198
Thanks for you input

I shot some 150 SMKs in my 1:16 twist. They shoot pretty good. I also used H4198. However, I was starting to overpressure a little early. I think a little slower powder might work a little better. The Sierra manual has a starting load of 24.9 gr of IMR4198 and a max of 30.5 gr. My experience is that H4198 is a slightly hotter than IMR4198. The Sierra table also list a speed with H4895. Much closer to 100% load density.

Luck with your 30BR, Tim
