Re: What would you Build ( Kirby and Ernie )
There are J-4 based 200 gr ULD RBBT and some heavier jacketed 200 gr ULD RBBTs as well. In the testing we have done with both bullets, the J-4 based 200 gr ULD RBBT was significantly more accurate then the heavier jacket so that is why you only hear about the J-4 version.
Richard is working with new jacket makers all the time to find heavier, tapered jackets to use on his bullets but for the time being, the J-4 based 200 gr ULD RBBT is the best.
With that high of a sectional density, penetration has yet to be a problem even on mature bull elk size game. Even with the very light jacketed bullet.
