I recently bought a new batch of the usual ammunition for my .243 (Sako Gamehead 113E)
Went out yesterday to check zero and found the groups were about 2"- 2 1/2" which shatered my confidence!
The things I have noticed about this new batch are:
Firstly: they look different compared to the old batch- they're all polished and shiny.
Secondly: its very hard to shut the bolt on them - you really have to push down hard.
Thirdly: they don't group well compared to the old batch.
I went out today with some of the old batch I had left and got a nice group (for me) instantly which has restored my confidence.
I've never had problems with this ammo before. Does anyone have any ideas whats up with the new batch?
