Hey all,
I'm looking to achieve 3250fps+ out of a 30-06 150gr. bullet and 3000fps+ out of a 175gr. bullet. I am using IMR 4350, and I get reasonable results (just over 3000) but, I WANT MORElol! I get 3500ish with 110gr, and I would like to get better performance out of my loads as I increase bullet weight.
up till now I have just loaded a sampling (usually in half grain increments from min loads to 2 gr. over max loads) and back off half a grain when I start to mushroom the primer pocket, as this would make the shell un-reloadable. There has got to be a more "scientific" way.
So far my own research shows that with IMR 4895 I can reach 3005 fps with a 150 gr. bullet @ 56,000psi (Hodgdons' web site) And I can get 2741fps with a 175gr bullet
I don't actually go till it mushrooms
These numbers are some diff from your 1st posting above, stick to them, forget the psi numbers, you have NO WAY of measuring psi!
1st post above says you do, my advice DON"T!
