For an accurate 70 grain Bullet, I have ordered 2 boxes of the Speer 70 grain TNTs ( 750 count ).... plus I fell into 16 lbs of H 322.. been using those to play with out of my multiple 243s for off season fun.....

can't say how the TNT will perform being fur friendly... but I question if it will, given the nomenclature of its name...

but who knows...

can verify the accuracy of the bullet and that powder is pretty darn good...running them in the 3200 fps range.... I think their limit is like 3400 fps in a one in 10 twist...and I am running them in a one in 9 twist...
