[QUOTE="Fiftydriver, post: 179923, member: 10"] I can not say for sure but you may be able to get a 200 gr ULD RBBT to stabilize in a 1-8 barrel. Best bet would be with something like a Rock thin land 5R(Good luck getting one in a timely manner) or possibly a Krieger 1-8 4 groove. The reason I do not list Lilja, there is no 1-8 twist 7mm barrel option. The cut rifles barrels are best for odd ball twist rates. The reason I feel that the 1-8 may stabilize the 200 gr ULD RBBT is because I am shooting them in 1-9 twist rifle barrels and for the most part have performed extremely well. All that said, I have not done it to prove it. TO get to 2K, well, from my numbers, you already have the right idea, a 200 gr ULD RBBT at +2700 fps is about the only way I see it happening in a specialty handgun, at least with a level of recoil energy that the firearm design(stock) will handle longterm and in a relatively portable barrel length for a handgun(18"). Only way to improve this I see, getting an aluminum tipped 7mm bullet that is roughly the same length as the 200 gr ULD RBBT but with a bullet weight in the 175 gr range. This would offer at least as high of a BC but with another 100 fps velocity boost. Now as you know, I do not believe velocity is the only way to get to extreme range, in this case however, your already using the ultimate bullet out there in the 200 gr ULD RBBT as far as accuracy and ballistic performance. Some of the solid VLD designs may run with this bullet but none will be as consistantly accurate over a variaty of barrel designs and bore diameters. Unfotunately, this is a waiting game for Richard to get the jackets and tips imported and then finalize the design, will the new bullets offer anything over what we already have, from what I have seen with the 338 versions, DRAMATICALLY!!!!
