[QUOTE="SMK1000plus, post: 1417625, member: 93846"] There are two occasions that I have seen this before: once in a .223 Rem with a 1 in 12" twist and firing 69gr SMK bullets and once in a 243 Win with a 1 in 10" twist (as in factory Tikka T3 and T3x rifles, Winchester M70s and others) firing 105gr Bergers. Both times the rifles shot their respective loads, here in FL, at @ 80°F and a few feet above sea-level, very well at 100 yard, only to tumble before reaching 200 yards. Most didn't even hit the 8-1/2"x11" targets at 200 yards but, of those that did, keyholes and obvious yaw was present. Very probable that you're using the wrong bullets for your rifles twist rate. YMMV [/QUOTE]
