I would suggest useing the reg xtp's instead of the xtp mag.If that is what you want to shoot.I used the mag one year with 100 grs of pyro shot 2 bucks in one week and lost both of them,one to find a few hours later and one three days later,both had pencil size holes through behind the shoulder hits,no blood at all,went back to the reg xtp's with no problem.
Another bullet to try that works is the sst,shockwave,and barnes in 250 grs.
Some of my buddies use the pb in 295 gr and they work great for them,only time I have used a pb was with a 225 gr 45 caliber in a knight disc,took one with it at 170 yds the deer dropped where it stood.
The sst or sw in 200 grs works great for me in my 50 cal encore,250 sst and 185 gr nosler in my ruger,and 250 sst in my savage
