[QUOTE="Buffalobob, post: 72328, member: 8"] Went and tested the bullets yesterday with some pessimism. The bearing surface on the 95 Berger is about 0.35 give or take and the throat on the 240 is about 0.31 give or take. Never one to trust my own calculations, I dropped a bullet down the chamber and then took a fired case and closed the bolt. Got the case and bullet back out by using a cleaning rod to ease the bullet back off the lands as the bolt opens. Sure enough, the bullet was just in the case by a gnats eyelash. Decided that this was not good when using an FN action because it is very difficult to ease a loaded round into the chamber without the bullet getting knocked around at some point. Seated the bullet by intuition on what I felt would keep the bullet aligned and still get as close as possible to the lands. This was probably about 0.15 off the lands. Loaded up 10 rounds all the same being as it was pretty obvious at this point what was going to happen in a 1-10 twist barrel. Fired 5 rounds at the 100 yd target and none hit the paper. Dropped back to the 50 yd target and fired three rounds. All were yawed out at about a 60 degree angle. Very interesting keyholes. Waited until the end of the day and shot the last two into the back stop to be rid of them. 105 Amaxs seated very close to the lands shot groups of about 4-6 inches and and were more than a little unstable judging by the oval holes. When all that testing was done a thunderstorm came up with swirling winds and rain and the little 70 gr SMK went 0.5 inches for 5 rds. I conclude that my gun with the long throat and slow twist, will not stabilize these bullets and the little short 70 SMK does not mind the long jump to the lands. It is a shame because they are some great looking bullets. Hope you have a better experience. [/QUOTE]
