Well there is obviously a lot of different opinions and experiences with all the bullets mentioned. I have shot the Varmint Grenades, TNT's, Blitz's, SPSX's and V-max's mucho times at little ground squirrels and lots of big jack rabbits. My opinion in a 50 gr weight is that the Blitz and SPSX are the most explosive followed by the TNT. Then the V-max. If a 36 gr. VG can be considered, it has been much more explosive for me than the others. But some folks claim they are inaccurate. I haven't experienced that. With all that said, I'm buying mass quantities of Blitz's and SPSX's since they are VERY impressive and much cheaper than VG's (typically 2 for the price of 1 VG). But when I find TNT's on sale, I buy them too. My experience has been they all shoot similar 1/4 to 3/4 inch groups.
