So here goes, I got a 243 win from my grandfather thats an old FNH with a 1:10" twist. I'd like to go as heavy as I can and shoot stable. I will be shooting between 3500-4500' above sea level so I know that comes into play a bit. I've heard mixed feelings on the 105 hybrids and VLDs in a 1:10" twist and I've heard you can get away with the 95 gr. VLDs but don't know if that is true. Berger also makes a 95 classic hunter that will shoot in a 1:10" twist but the BC isn't as high and haven't heard anything about them. My dad has shoots the 215 hybrids in his 300 RUM and really likes them but I'm not opposed for shooting VLDs. Any help would be appreciated so I don't have to buy a million different bullet weights/types; and I don't have any particular powders picked since I want my bullet picked first and go from there. Thanks ahead of time!
