New Alloy

[Kurt]

Mike the patch is needed for the bore riding to keep it straight.
What made me to try this alloy work is when I shoot my HP rifles and I see those 1/2" groups at the 200 yards and I look at the chronograph tapes and I see those high ES and SD's 50 fps or more for the ES and when shooting my powder rifles with the ES's below 10 fps and SD's down in the low single digits and I cant hold those 1/2" groups @200 this makes me scratch my head. When I stop to mull it over one thing that comes to mind and that is the jacketed bullets hold the integrity of the ogive and the rest of the bullet to get kneaded out of shape like donut doe like a lead bullet with the wrong alloy temper throwing it out of balance. I might be wrong but I don't think barrel harmonics of the wrong primers alone causes it not when I look at the low es and sd's
But I might be wrong, been so before
But when you look at what a wrong alloy like the bullet below with a slumped nose the alloy most use might be something to look into.
