I've got a 17" Contender barrel that I cut down from 23" so I could use it as handgun or rifle. I shot a decent 8 point whitetail a couple years ago at about 125 yds. Hit him right behind front shoulder and exited right behind opposite shoulder. He ran most of the way right to me-probably got to within 50 yds of me before he fell. Lungs were gone. A lot of internal damage with no meat lost. Was shooting 110 gr Nosler Accubond with 28.0 gr H322. Shoots good in my barrel.
my most accurate bullet is the Hornady 120 gr SST makes a mess if you strike bone,followed by Barnes 110 TTSX, some heaver 130 shot a bit better but were way to slow to be reliable, I have not yet tried Barnes 100 grain but think it will do better on deer than the 110 TTSX which did not expand well
Report time...got the 120 SST's and set'em on top of 27.0 gr H322...Lights out Baby! Three shots, all holes touching at 50yds. Gotta get it out to the 100yd and further mark, but probably won't be until after Bambi season. Haven't cut the barrel yet, but will soon. Haven't gotten it bloody yet either, but working on that right now.
