[QUOTE="XLR Industries, post: 2569741, member: 123236"] I do not think any of our sponsored shooters have bedded their chassis and a few of them actually talk about doing this test with their chassis and seeing very minimal shift when taking barreled actions in and out. If you listen to the Straight Dope podcast, Chris Way talks about it and he wants to shoot a match where he takes his barreled action out after every stage. I know personally when I take my rifle apart completely (barrel off the action, scope off, and obviously action out of the barrel) everything lines up within 1 moa. I think as far as the shift goes, it can be very dependent on how meticulous you are with the chassis-to-action connection. If you are taking it out and cleaning the bottom of the action and the chassis with a little bit of acetone and a q tip then you should have better results. It would be a great experiment though to see whether that is caliber-dependent, or if a muzzle brake affects it. I had a customer tell me that with his 300 Norma and a 5 port brake, the port catches enough energy to slide the barreled action forward after every shot. I am not sure how he measured this at all but I would love to test it out. I just got done testing a 300 PRC in a Magnesium chassis this week and I did not see any POI shift over 100 rounds in 3 days. I also know that my 6 BRA has zero POI shift over 100s of rounds. One note here too is a lot of guys talk about POI shift in their equipment but body position, natural point of aim, and even correct parallax can also have a large effect on your poi. Even guys in the PRS world shooting 25 lb BR variants see a shift from their prone zero to a positional zero. So with a heavier recoiling rifle that is 10 lbs, the effect is going to be even more transparent. Just some food for thought from my end but I would love to see some more guys testing it! [/QUOTE]
