These loads are max. in my gun and with wildcats I recomand that you start down by at least 15%.
In general I like to keep heavy for the caliber bullets close to the lands, .010 to .015. The data here was form a 1 in 8 Twist 26 in. barrel and ran through an Oler crono, no presure testing, only obseveration of cases. All load data with 80 gn. Sierra, unless stated other wise.
RL-22, 47 gn. ave. vel. 3516 fps.
RL-25, 48 gn. ave. vel. 3543 fps.
AA Mag. Pro. 48 gn. ave.vel. 3359 fps. Might be better with standard primers than mag.
H-870 you can fill the case and only get abt. 3,200 fps, but very accurate. use mag. primers. __________________ Catfish
