Factory Remington 7mm SAUM - anyone know the powder?

[wildcat284]

Hey guys,

I'm guessing Alliant Reloader 19?

I picked up a almost dusty box of factory Remington 7mm SAUM, loaded with the 150gr Corelokt. I wanted to see how Remington Brass compares to the Norma 300 SAUM that I am using for my 6.5mm SAUM.

I was initially going to dump the powder, then resize the neck and reload with H1000, however I decided to reuse the powder. So after weighing the powder from the first case which happened to be 60.5 grs, I counsulted my Nosler reloading manual. They list 60.5 grs Reloader 19 behind their own 150gr projectile.

I loaded 60grs behind a 140gr SST and at the range today, I had one 3 shot group of 0.458 and another tighter group of 0.383. This was out of a Criterion 24 inch fluted 1:8 twist.

I've been trying H1000 and have consistent 1 inch groups, but If Reloader 19 is the powder that produces groups this small, then I want to get some to try.

Please don't assume your dumped powder is RL19. Your thinking is dangerous. The ammo manufacturers use bulk powder, custom blended to work with what they are trying to load. You cannot duplicate it or buy the same powder off the shelf at your gun store. Probably just a coincidence that 60.5 happens to be the recommended RL19 load. Go by the book. I usually cross check two or three books to assure safety.
