So I'm building a fast twist 1-7 257 WTBY. I had Manson reamers build me a reamer to black Jack spec's. I plan to run Hammer 128gr. Would u use Sammi reamer or blackjack specific reamer?
Also anyone running blackjack 131 in 257 WTBY can you give me a COAL please I've read so many different things depending on what reloading manual you using makes my head hurt and all of them only go up to 120gr bullets.
thanks
Billy
