[QUOTE="Playtimefun, post: 2790482, member: 103742"] Going to have some fun here... just bought a Ruger M77 in 257 Roberts and debating rechambering to 257 Ackley Improved (has a 22" barrel). Here was a write up I found... it's interesting to read this when by the same standard then the creedmore and others shouldn't be used past relatively short distances. This is from...
