Yeah, my Savage shoots 'em fast too, 4100-odd fps. My buddy's 26" remington barely cracks 3900. Haven't used those particular ones on gophers as the idea of shooting factory ammo in my baby... ewww. (I only shot a couple to see how fast they went) Handloaded 52gr HP match bullets at a tad under 3900 work well. VMax's REALLY make a messbcsteve said:I tried the 45gr out of my Savage 22" barrel .22-250 and they broke the advertised 4000fps on my Chrony. They averaged 4010fps if I remember correctly. I was pleasently surprised.
FMJ's work on gophers in larger calibers, 7.62x39 milsurp works OK, if you can hit 'em.
