I am developing some rounds for my 270 with the Speer 90gr Moly Hollow Points and with Speer TNT 90 grainers. You have to keep the TNT below a certain Ft./S to keep them from dissentigrating. I think it is 3600 but I am not sure. The reason is because of the ultra thin jacket on the bullet. I have shot some crows with 110 gr. before, wow a big poof of feathers.
