if i could have any rifle for my personal use it would be the barrett model 99 chambered in .416 . This bad boy is better than most and imho, maybe the best period. your neck of the woods, or desert rather, would be perfect for it. its hard to get the distance here in the north east to really let it stretch its legs.
i swear i could spend 100k on barrett guns and ammo. in under 5 minutes and still not be done.
may wind up just saying eff it and getting a barrett AR-15 lower and an upper chamabered in 6.8mm. later this year. that 6.8 is a mean customer compared to the 5.56. like a .22 mag vs. 30-30.
i have a stag 6.8 upper. but i would really like to have the whole upper lower package in barret.
mark my words, the 6.8 owns the 5.56. many special forces outfits are now using it. essentially the same recoil, but the downrange energy is just amazing for it size and holds up well out to 300 yards.
why am i preaching to you about it, i don't honestly know.
