[QUOTE="Brown Dog, post: 19913, member: 1622"] Subsonic, I think that checking of zero is more a 'system' thing than just a scope thing. Personally, I'm verging on check zero paranoid (you'll understand why by the time you've read this!); I feel uncomfortable doing more than a couple of trips afield without firing at least a check shot at something! We're all slaves to our own experience; hence (I suspect) Pete's downer on the AI mount. My worst loss of zero ever was on an occasion whilst my PM2 was mounted on my Sauer 202. Sadly I discovered the shift on a beast rather than a target. The 1st beast dropped to a liver hit at around 150m; rather stunned at my inaccuracy, I persuaded myself that I must, somehow, have unwittingly pulled the shot. I'm rather ashamed to say that I then cracked on with the outing; the next shot at an animal at around 230m hit the beast in the gut (I hasten to add that I now twigged the error and aimed-off to drop the animal with a 2nd shot).I later found that the POI was about 60cm right of POA at 230m. The cause wasn't the scope; it was - I later found- the fact that the locking nut on the front Badger mount had quietly slackened itself off. Re-torquing it put the rifle back on zero. -my point being that it was a 'system' loss of zero rather than just a scope problem. Conversely, I once had a 15cm zero shift at 200m with a Swarovski 3-12x50. I had accidentally bumped the objective on a door frame; a bump that I thought so light that I paid it no heed. But the zero shifted. A solid scope problem that time! Now my PM2 sits atop an AW rifle (in the AI mount that Pete so strongly damns!). Despite some rough use (this rifle encourages rough use!)the zero does not budge a jot! -with this set-up, both my 'system' and 'scope' trust increase on a daily basis! I suppose, what I'm trying to say, is that your 'check-zero' interval will depend on the 'system' trust that you will develop over time. I feel quietly confident that your PM2 will not reveal itself as a weak link! (Pete: Quit those negative AI vibes! The AI mount is in service on the L96, the L118A1 and the L115A1.
