I can get projectiles from Hornady in 70g in 227" and Norma and RWS make both types of ammo, I am thinking of getting the 22HP as the 70g pill would be better on bigger game than the 5.6 but I was also looking at a chamber insert to turn the 5.6 into a 22WMR for cheaper shooting but I would presume the sights would not be regulated? any advice on chamber inserts ,lothar Walther make them.

22LR, 22WMR insert for 5.6x50R

22LR, 22WMR, 22Hornet for 22HP

getting a insert would make the Drilling more versatile also LW sell inserts for 12g so you can shoot 20g,16g and .410 but back to the rifle a insert say in 22WMR is a .224" but the 22HP is a .228" would this matter? also the 22LR and 22Hornet are 222" I think so now I am thinking 22WMR for the 5.6 as both are 224". Do the different sizes have much affect on accuracy? Thanks
