To be perfectly honest, i would not know how good the Parker bulletsare if i didn't try them. I shot 15 Or 16 Deer last year. I actually lost count. Seven with Parkers. Three with the soft tip SST'S. One with the T/C Shockwave. Two with 300grn Deadcenter in a FlinLock. I actually dont remember the others. Always searching for something better. I really think the Lehigh will be the ultimate bullet. I already think the current bullet is at 150yds and under. Time will tell that's for sure.
