OK 200 yards,Savage 10mlII smokeless powder muzzleloader,45 cal. 300gr hornady xtp bullets and H4198 powder. and the reason I went half a grain is because its a muzzleloader.
never laddered a muzzle loader before... tough to tell from just the target, but if it were me, id load a few ( doh... you know... at the range /ubbthreads/images/graemlins/crazy.gif) at 65 and 65.5 and see how they grouped. Thinking of it as a sixty -70gr capacity rifle, I think the large steps in powder would hurt more than help. id still do it at .3gr were it I.
I've got a win x-150. With 150gr. 777, it kicked like a mule, grouped more like a shotgun. Dropped it down to 100gr. triple seven powder with a 405powerbelt HP, and shot a 1.25" & .75" group @ 100yds with peep sight /ubbthreads/images/graemlins/grin.gif...if that helps. Now if W.A. state law allowed a scoped muzzle loader.... /ubbthreads/images/graemlins/cool.gif
I am going to assume that you were shooting 3 shots pause, 3 shots pause based on the groups that I see.
If I am correct, then i think that 64 1/2 thru 67 is pretty good since these are actually two separate shooting sessions, with different sight pictures, etc.
I'd like to see a 65 grain 5 shot group. And call all of the shots /ubbthreads/images/graemlins/wink.gif
Good to see you here edge. I was going to post on the doug's board but didn't know if the fellows over there had ever tried this method because I have never seen it mentioned. By the way the shots were each timed 10 minute apart. No 3 shot groups
