Thanks Rob!... I dont know if you know that, but in my country the reloading materials as bullets, powder, etc etc are very few and also controlated so the little amount who we can use are really very limitated... Here, the W748 are a rare thing, I never hear abot that... I use an argentinian powder, named as "A27", produced by the FM factory... As ineresting thing, in my Remington Corelokt 165 gn bullets, I use the same ammount of powder (A27 as i said) 42 gn In my 18" barrel the bullets flight as 2600 fps inthe mouth! I might both powders shoul be similars... Greetings!
