Ok here's the setup: .50 caliber 100 gr. pyrodex pellets 295 gr. powerbelt bullets. Shot two perfect bullseyes then tried a third shot and hit 6-7 inches straight left. What is going on? Could my scope have been bumped or what? I try to use the same amount of pressure with the ram rod every time. Could that be a problem also? Could I have just jerked before the shot or what? Thanks for the info.

It could be any number of things. Shoot five more, and see what happens. Sometimes you get a flier.

03: had the same problem in both my inlines one a c.v.a. 50 cal. the other a 54cal by t/c with the powerbelt bullets will shoot a groupe of three or four rounds would allways pick up a flyer as much as 6 inch difference on paper well the answere was I don't use the powerbelt anymore switch over to percision sabots and problem is gone the only other thing I do shoot pyrodex select loose powder try another type of bullet and see what happens.

I too noticed some fliers with Power Belts. But it did not happen when I was using Clean Shot powder.

Keep yore powder dry!!
