[QUOTE="Mysticplayer, post: 260934, member: 8947"] Byran, I figured manf had a large role in why we are seeing an upper limit in bullet weights. Seems that once we need a 7 twist, things get real flacky. Which means, the 7mm and 30cal still have room to grow:D I think a 190 to 200gr 7mm VLD with a BC around/over 0.74 would be interesting. Would be a very useable bullet for all sorts of applications and pushing them to 2900+fps would be a no brainer as far as cartridges/powders go. Ever consider using a lighter core? or a different jacket material? With a lighter core, you get the same BC but can now go faster. Some polymers have pretty high melting temps so core failure would be greatly reduced. it would require a major change in how we make bullets, but couldn't a material change push the limits further?
