Mentioned this earlier, but the post disappeared in the crash.
Hornady has been making EXCELLENT brass for at least 3 years now. Have purchased it in .17 Hornet, .243 Winchester, 6mm Creedmoor, .250 Savage, .25-06, .275 Rigby (aka 7x57), 7mm Remington Magnum, .30-06 and .300 Weatherby Magnum at local stores, where it's generally inexpensive. A good example would be the 50 pieces of 7mm Remington Magnum I bought for a magazine assignment, which proved to be as consistent in both weight and neck-thickness as several other premium brands, including Lapua. So I went back and bought another 50...
They do not offer component .257 Roberts brass, but they do offer their Superformance load with 117-grain SSTs at a listed 2945 fps--which is as inexpensive, per round, as some component brass these days (depending on where you buy it, of course). Picked up my first box today at a local store (the only one they had) and will report on it soon, both the ammo performance and brass quality.
Also saw some in an more distant local store a few weeks ago, and will see if it's still there next time we make it to the "big city."
I shot that Superformance ammo with the 117 SST in my custom, 5 shots over the Magnetspeed avg velocity 2820 fps and SD = 20.0; accuracy was minute of hog/deer as well
I bought 5 boxes in case they shot well and would all be from the same lot...since all my shots are under 250 yds really no need to reload but I will of course! I really want to try the 90 gr GMX but will work up an accurate 100 TTSX load first sine that has been my go to bullet for years
