ramshot powder data

[bloodman]

is it safe to use data that was developted for a rifle with a 1-12 twist in a rifle that has a 1-9 twist? I will be using 55gr. bullets. this data came from ramshot.
thanks any reply would be greatly appreciated

What bullet,Ramshot powder? use in an AR? it can generate higher pressures you just 'start' lower and work up.

I load a 55 grain bullet with Ramshot Tac at 25.2 in a 1-8" twist 24" barrel ,I still am low at 3025 fps but faster isnt usualy the most accurate.

the bullet is a montana gold 55gr fmj, the powder is ramshot tac. the starting load is 21.6 the max 25.7 it will be fired out of a bushmaster ar15 with a 1-9 twist rate

You'll be fine with that. You'll find each additional 1 grain added will be approx 100fps faster. Its not that 'accurate' of a powder but makes fine cheaper blasting ammo,a touch dirty and smoky compared to IMR /Winchester powders.
