No positive numbers on the Wildcat Bullets yet. I know he is talking about possibly three different bullet weights, 350, 375 and 400 grains.
If they live up to the standards his 338 caliber AT RBBTs are producing in early tests, I would estimate that you would see possible BCs in the high .8 to high .9 range at least depending on bullet weight.
With his 265 gr AT RBBT 338 bullet, I have to use a BC of .930 to get my handheld to match up to actual bullet flight.
From what I have seen comparing them to conventional solids like the LRB bullets, they are extremely similiar in BC for given bullet weights.
YOu are correct, if your bore is set up correctly for the solids you will get great performance. If your bore is a bit tight or a bit loose, you will get very inconsistant results. That really limits the different barrels you can use with the solids.
The nice thing about the Wildcat bullets is that with the lead core, they will be much more forgiving as far as barrel to barrel bore diameter variations and still offer similiar BC values as the LRB style bullets. On top of that, they are an expanding bullet, much better for any big game hunting at long range and in some states, solids are not even legal to use on big game as most states require an expanding bullet to be used on big game.
Not saying the Wildcats are superior as far as ultimate performance, just far more flexible and consistant over a wide range of different barrel brands and velocity ranges.
