I to have pushed the TNT bullets far past their listed velocity limits and in a 1-14 twist barrel they generally shoot very well. In fact I developed a load for a customer using this bullet in a 22-250 AI I made up for him and using H-380 we got an honest 4000 fps with the TNT. I would not have believed it had I not seen it over my own chrony.
If you shoot a 1-12 or 1-10 you better stick to the listed velocity limits.
As far as terminal performance, As already stated, would be real hard to pick one bullet over the others out to 300 yards at these velocities. They all retain plenty of velocity to make dramatic expansion on light game.
If you don't think you "NEED" a Boattail bullet, and to be honest, to 300 yards there is no real need, the 50 Gr TNT will perform very well.
It does not have the B.C. of the tipped boattail bullets so wind drift will be more but not dramatically more over 300 yards.
THe nice thing is they are cheap! Compared to the Ballistic Tips. Personally I used to shoot the Ballistic Tips and Ballistic Silvertips exclusively but I got a real good buy on some 40, 50 and 55 gr Sierra Blitzkings, 1000 each so not I use them in everything from my 222 up to my 22-6mmAI. They are very accurate and in my experience are equals to the Ballistic Tips in terminal performance.
Since then I have tried the 52 gr FBHP Wildcat Bullets and have been very impressed with their accuracy potential. While they may not be as dramatic at say 222 and 223 velocitied, when driven to 3800 to 4200 fps, pretty much any bullet will turn a sod poodle inside out in a hurry!
Will be using these when my Blitzkings dry up.
To be honest, use the bullet that groups the tightest and never look back. You have enough horse power to make any varmint bullet pop real hard.
Good Shooting!!
