My newest project needs such a bullet, and I have made some detail changes to an earlier proposed 68 gr. BBT design.... I'm hoping that Al will be able to make the RG moulds work for small Meplats, and if he does, that should make this bullet a reality....
If you are interested, please post at this link.... My new TJ's barrel is a 9" twist, and I am pretty confident that this will work.... The Kolbe Twist Calculator seems to be pessimistic on the required twist rate for boattails…. They usually work in a slower twist just fine....

If the gun in use has the umph to push them hard, it should make for a fantastic longer range varmint bullet.

That's the plan.... *WEG*…. 3800 psi in a 28" barrel with a valve set up for a .257 should do the job.... They have the same SD as an 85 gr. bullet in the .257, and I can drive that at 960 fps (174 FPE)….
