RE: Black Powder groups
Well I never shot a deer with a shockwave either. Still a lot of deer have fallen to them. So they must do something right. I really think it boils down to shot placement. I do think the Shockwave is not meant for short range shooting. In cases where my shots were under 100 yards I would look at the Barnes, Nosler, Speer, even the XTP's. They are going to hit, expand, and should exit I hope.
Plus I tend to believe the trend these days is to design your rifle to shoot your projectiles. CVA/BPI for instance tout the advantages of powerbelts, and their rifles normally do shoot powerbelts very well. Knight talks about the RED HOTS which are Barnes bullets. So it would only make sense that Thompson Center might promote (Hornady created) a rifle that shoots some of their bullets well, and here come the Shockwaves.
I have been shooting some Nosler .451 diameterPartitian HG 260 grain out of a few of my inlines. My Knights love them and so do my Thompson Centers. These I think are a well made bullet. Sabotloader and others sure do appreciate them when hunting. Just another bullet to keep in mind.
Next week I will be testing some Parker Production 250 gr Ballistic Extreme in a couple rifles and see what kind of accuracy they will produce. I like the looks of the Parker. They look well made. So range time will tell.
