Ok, so I have pursued higher vel (for a 10 twist .308) at 500yd and been moderately successful. My solution was a heavy bullet (Accurate 31-210E) at 2300fps. Was fairly accurate, but, the recoil became more than I really wanted. So, I've gone back to the XCB (167gn) at slower speeds and limited my shooting to 300yd. Found a nice sweet spot at 1750fps. It works with powder coating and conventional lube. I've been using the lubesizer just because of the convenience.
I was at the 1000yd range one day shooting the 6BR and had targets also set at 500 and 200yd. It was a very calm day so I was having way too much fun :)
Got the .308 out with my cast loads and had several good groups in a row (<1.25MOA). I looked at the 500yd target and figure what the heck. Calculated the hold (a LOT) and touched off a shot. It landed close to the gong! Proceeded to shoot some more and got a couple hits (5" gong). So, put some on paper and had a 6" group. I am now kinda interested in this.
Today went out and put targets at 600yd. A little wind, ~10mph quartering headwind. Shot an 11" group.
So, why does this combination work? Anything I would come up with would be a SWAG, but, the bullets are shaped like the long range BPCR stuff, so maybe there is a correlation. I do know the wind blows the things around a bit and they take a while to get to the target :)
As circumstances permit I will continue to shoot these 'lazy' bullets at longer ranges just for fun. FWIW, at 600yd my scope ran out of adjustment and had to hold over on the reticle. Maybe need a 20MOA rail for this one :)
