New peashooter 300 RUM

[hemiford]

I've decided to build this one a little different. 300 RUM dedicated to 150 grain projectiles.
Rem 700, 30-inch barrel. Seriously considering HBN bullets and barrel coating. 1:12 twist

I'm just guessing MV in the neighborhood of 3500~~3800 fps.

Are there cup and core bullets that will stay together or should I just consider mono ?
Should I consider a shorter throat than SAAMI ? COAL won't be very long.
What powders to use, quick burn or slow burn ?

Thank you !

I shot the 152 Hammer Hunter in a 28" RUM at 3504 fps with H1000.

This was to fit in an HS DBM at 3.6". It had a 12 twist as well.

Thanks for the info, I know it's not the usual to shoot shorties in a 300 RUM !

Two 300 runs ago i shot 150 ttsx at 3675 fps with RL 26 in a factory rem 700 long range.
It was crazy accurate and would shoot 3" group at 500 yards.

The swift 150 scirocco will also hold up.
Hammer, barnes, Lehigh, badlands will all work i would think.

It would be hard to not want to shoot the hammers in this rig. That will be a mid-range laser beam.

Not too many frangible bullets in 30 cal these days at 3500+fps.
I recall 130's coming apart, but I think they were faulty, the core was slipping in the jacket.

Cheers.

I have a friend who shoots Nosler 150 gr Ballistic Tips out of a 300 Weatherby with a 1-15" twist at 3500+ fps, it's like a lazer beam and drops animals like a lightning strike.
