My buddy spent a year and 2 different Remlins back to the factory and they finally sent him his money back and he bought a 30-30 Handi in time for MO. deer season. now I have 2 weeks to get him a load to shoot steel chickens thru buffalos at 200 yards.All my experience has been with cast FN in my Marlins in .30 caliber except in my 30-40 Krag,220 Lyman and 220 speer. I have plenty of 45-70's in lever and single shots but he wants to shoot his rifle, so I am going to try some 165 gr. Hornady S-P ,because I found some in town today. Powder wise I have H4895,RL7,H4198,5744.2495 and Imr4350. my question is any one of those preferable. I have been shooting B-P for most of the last 15 years.any help would help ,as always I will use a manual and work my way up, Thanks Bill
