The Mler weighs in @ 9lbs so it doesn't have much of a kick at all with 90gr of FFFG and a Round Ball, I have never shot or tried a Conical/Mini Ball or Buffalo Bullet" out of it and had no reason to. I'm not going to shoot past 100yds as I said before that most of my shots on Deer are between 20-50yds. I mostly wanted to know what others have found to be their Maximum Limit when using a Patch and Round Ball with whatever load they have behind it. Thank's Again
