RFB,I plan on shooting my Mark II and 10/22 more regularly.
I have yet to see a video or discussion leading me to believe that there is any reliable expansion or benefit to HP in .22LR.
Yet seemingly, more than half of available choices deploy a HP of some kind that turns already finicky semi-autos into jam-o-matics.
I’ve always used a copper coated round nose.
What am I missing?
I'm with you on that. Have to match the round to the purpose. HPs have no advantage for shooting paper and would be a PITA if not feeding in a given gun.
I'm using a Ruger American Rimfire bolt gun most of the time that I am hunting small game and keep my ammo consistent to avoid having to re-sight in.
Found this nice vid comparing .22LR HP expansion for this purpose:
