the AR 15 load is a hornady bullet ,its alittle hard to get ,its a 123 gr V-MAX part # 31442,i have only found it in one mail order catalog, Graf & Sons, for my gun the OAL is 2.283, or as long as the clip will allow.
powder is H335 31.5 gr. winchester brass, Fed 210 primers.
the mini-30 likes this load as well ,but a shorter oal,
(its a mini 30, i dont expect much from it )

the encore rifle has a preference for AA 2460 power and sierra 125gr bullets

the encore pistol likes a sierra 125 gr fnhp bullet made for the 30-30
# 2020 ,the bullet set out as far as it can, the base of the bullet is in the brass about an1/8''
the power is H4198 a full case of it ,its a very hot load, i would not dare try it in any other gun. its what this gun likes ,and its a tack driver
