also why do the fulla's that test rifles in magazines only shoot poxy 3 shot groups ?

If you've got the right twist rate and consistent speeds then an accurate load at 100 should be an accurate load further out. Load testing at 400 meters would be somewhat ridiculous due to wind etc.

If it's shit at 100 it's never going to be good further out. Your angular dispersion isn't going to improve once the bullet has left the rifle. If you're getting "better" results (in angular terms) at longer ranges than 100 meters it's parallax or something.

The magazines shoot 3-shot groups because it makes the rifles that they are trying to sell look better.


I don't actually like shooting groups at all, it's not the most practical training. That day I was just mucking around with my zero and found the target in my rangebag last night. Always see people saying "my rifle will shoot MOA all day long" etc. Okay, so prove it then.
