Chap,of all the savages that I have set up or helped set up he last 3 0r 4 years only a few of them shot better by swabbing between shots,wanted to mention it because the savage is like any other type of muzzleloader useing little tricks to get better accuracy.Most are useing the IMR4759 in different grains,one fellow is useing IMR4227 and won't change,he says he has killed deer out to 280yds with it and going to keep useing it.A couple are useing the 5744 and like it.One fellow was very hard headed and used the dippers to measure his 4759,and couldn't get it to shoot too good at 100 yds,he had a friend with him and he wasn't hard headed and listened,by the time we had his rifle set up he shot a 3shot one hole group,a week later the other fellow called me and said he that he had finally shot a one holer,I said you weighed your load didn't you and he addmitted that he did.
Another thing that has helped my savage to shoot more constant is that I had my buddie to bed the recoil lug,I tightened the front screw and never touch it,unless I am going to strip it all the way down to do a good cleaning,to clean after range trip I just turn the back screw enough to get the bolt out.
The only requirement if I am going to help anyone set up a savage is that they clean the barrel with JB bore cleaner with at least 200 strokes.This gives them a very clean barrel to start with and saves time in working up loads..
The mmp short sabot is a good choice with the xtp,below is a pic compareing a knight sabot to the mmp useing the xtp's.
