I owned both before my TBA. I have AK ammo in HP and ball; the AR ammo is all ball and I haven’t seen any in HP>
Most of my rifles are bolt action or lever. All are 30 caliber or larger.
I do reload for family members. Am working on two loads for my brother’s 22-250 rifle right now. One with Hornady 55 gr HP and one with Speer 70 gr Semi Spitzer SP. It took effort to find components for that. Brass and bullets were hard to find, but I was lucky and found some new Star line brass. Good stuff.
The only semiautomatic rifle I own is a 7.62X39 (30 caliber). I reload for that too. But bought some (Russian) Barnaul SP ammo for it a while back.
I reload rifle, pistol and shotshells.
