Rifle harmonics are a weird thing. The bipod must've distorted the stock by just a few hundredths or thousandths of an inch and messed up the synergy of everything. Strange things happen!

This. 

I am an engineer.  I look at a heavy barrel .22LR rifle like my Savage BTSV, then look at the tiny cartridge, and my first thought is that tiny little cartridge isn't going to excite that heavy barrel very much at all.   Then I read about barrel tuners, free float, action torque, etc. and got a few thousand rounds down range and decided that a .22 was the most challenging of the long guns.

That is the only thing that I can come up with that would have caused my issue. I had it so tight that the weight of the rifle sitting on the bipod caused a slight twist in the stock, possibly resting it against the barrel. Depending on the amount of weight exerted on the bipod, the point of impact changed. It wasn't a lot, but enough. I now have a new respect for these harmonics.

I'm breaking in to CZ with a 455 American. It might be my first CZ, but it won't be my last.

I watched a few videos on adjusting the action screw and it's amazing how a few pounds here and there can affect the point of impact. Apparently, this holds true with any exertion on the stock.

Heres a simple but true rule....until you use good match ammo you wont get any kind of repeatable target accuracy, high velocity is fine for hunting when 1 1/2" groups will take game at 50 yards and in but I havent seen any benchrest shooters using mini mags

My primary focus is to get the accuracy necessary for humane shots on small game, typically inside of 50 yards. I've never been accused of being a bench rest shooter. ;-)
