winchestor 209s
Shockwave superglide Sabots(bonded or plain work fine) 250 grains
2 pellets or start off with 90grains of loose powder

After about 6-7 shots you will probably be ready to step up and try different combos. I perfer 115grains of Blackhorn powder with a 250 shockwave sabot. It doesnt have the kick of 150 grains but will shoot fairly good out to 125 yards. Decide how far you want to shoot. Some like 200 yards shots. I perferr keeping it under 100 yards. If so, 100 grains works fine. If you want to go 150-200 yards then 150grains of powder will be needed to ensure a good kill shot.

every ML'er is different. If it doesnt group good, keep trying. Its fun and enjoy shooting. The more you shoot, the better you learn your gun
