Buy a box of the 160 gr hornady leverevolution ammo and shoot it off a bench and bags at 50yds for groups comparing it to other loads, see if ya can get it "zeroed" about an inch high at 50 and then shoot it off hand.
I shot 4 different types of factory loads in my marlin 36g .30-30, the hornady is tack driving stuff.
I would spend 50-75 bucks on different ammo and do some shooting on a bench at 50 yds with it, before spending alot more. Jmo.....
Might surprise ya and save alot of money.
