CorBon has thousands of dollars worth of equipment for evaluating load performance, as well as guys who load and evaluate ammunition as a career, not as a hobby. They also have access to powder types that you and I don't. If they could go faster, they most certainly would.jcwat said:if corbon can make a round that runs 3800 fps. why couldn't i safely go just a little faster???
If you don't have the need for a 22.250, then you don't have the need for 4000fps. The .223 wasn't designed for those speeds. The .223 WSSM doesn't even hit that number. A lot safer to get the caliber that will do the work, rather than trying to push the .223 to being something it isn't.jcwat said:well i guess i'll just stick to the .223. i don't have the money/need for a 22-250. maybe i can find a smaller gr. bullet. less than 40 gr??? that should push up the fps.
