I once owned two Rugers, one Model 77 tang safety and the other Mark II, both in 7x57mm. Both seemed to like 154 grain Hornady BTSP with Winchester 760. I later traded to a CZ 550 American in 7x57, and Ran into Ray here on the internet here who suggestd I try H414. The twist on the Rugers were 1x9.5 and the CZ was1x8.66. So, I moved up to the Hornady SST in 162 Grain. With Remington Cases, Frontier 210 primers, 48.3 grains of H414 powder, my choney was showing an average of 2,815 fps at an elevation of 7,000 in New Mexico. Groups were ging sub half inch at 100 yards and one group went .216 inch. With 160 grain partitions, this same load produced right around the same results. I had a one-shot kill on a nice bull elk at 325 lasered yards, mule deer, whitetail deer, black bear, antelope, javelina, wild hogs and even a wild texas turkey. No American manufactrer makes a 7x57 today. I think that is while all were trying to hype the 7mm short mags, there were too many 7mm on the market and the 7x57mm was a Euro Cartrige in the first place. You can still find them. GunBroker has a few listed right now, a few Rugers and couple of nifty Whitworths manlichers. In addition American Hunting Rifles will make you one up using a CZ action, a proprietary barrel and McMillan Stock. It is a great cartridge. Tom Purdom
