I just stumbled upon a straggler of a bullet that was in a box of .277 90 gr. TNT's. It is the .224 55gr. TNT High Velocity bullet. I have shot some 50 gr. TNT's but I guess I didn't even realize they made a 55 gr. in .224 caliber. At first I thought it was a 50 gr. TNT, but after weighing it, I found out it was a 55 grainer. After checking Speer's website, I see where they make a 55 gr. TNT High Velocity bullet. Anybody ever try these in a .223 or .22-250? I'm thinking I may have to pick up a box of them and give them a try in the black rifle but I'm not sure what the velocity and barrel twist limitations are on this bullet. Anybody know?
