For general use out to 250 yards I use an AK47 and 74, I like the 5.45×39 round used in the AK74. For medium to long range my DMR of choice is the M14 with a good piece of glass the 7.62×51 is good to 1000 yards. For long range and beyond I use a 338 Lapua Magnum round fired from a Savage action bedded in an accuracy international stock. For close range I use a Vepr 12 shotgun, being mag fed I find it to be a very fast loading versatile shotgun.
I find the AK’s including the Vepr 12 are dependable and easy to maintain. So they would be my main choice as well.
Sabres out! Sabres ready!
