I don't know about what 30-06 you are selling, but suggest that perhaps you try different weights and powders. The attachment was shot with a Ruger 77, tang safety, 26 inch, 1:10 twist Lilja barrel. Note that the notation on the target is incorrect, the bullets are not 199gr Sledge Hammers they are the 199 grain Stone Hammer bullets. There is a difference in POI because of a scope adjustment. That load was getting around 2500fps+. Despite what some readers will say, I have found Hammers to be finicky for one reason or another. In my son's AR (.450 Bushmaster) we had an issue with pressure and had to decrease the load. We also had an issue with his AR with the bullets moving forward when cycling. So he reduced the buffer spring and we put a heavier crimp on the bullet. I have loaded the 223gr Stone Hammers in my 35 Whelen, only to find that I have to seat the bullets deeper, than the recommended COAL, to get them to chamber into my rifle. This was an unfortunate error on my part because I changed bullets just before a black bear hunt without any range time. I ordered them "last minute", the folks at Hammer did a great job getting the bullets shipped and out to me, my screw up there. Presently I have been "trying" to get their .452, 221gr Stone Hammer Bushmaster bullets to feed in my Ruger Hawkeye rifle. This rifle will feed anything that I put it in, but......this bullet. I believe that the ogive is a little blunter thus giving me the feeding issue. I am "not" selling the rifle, I "am" working on the rifle to get it to feed. Seating depth and polishing the feed ramp and removing all of the receiver burrs are on the the bench right not. This .452 bullet with a weight of 221grains in the .450 Bushmaster is the perfect weight that turns the Bushmaster into a formidable black bear cartridge. For me it is the perfect weight/velocity bullet for the cartridge at 2500fps out of the Hawkeye. The second attachment is a 50 yard target that was recently fired with the Hawkeye. The top three shots are Barnes 250gr TTSX bullets, the bottom six are a combination of Hornady black 250 grain bullets (3 rounds) and of the Hammer 221gr Stone Hammer bullets (3 rounds). I was glad to find that the Hornady Black 250gr bullets shot same POI as the 221gr Hammer bullets. I cannot explain the horizontal stringing, probably the loose nut behind the trigger??
