[QUOTE="Hespco, post: 2236907, member: 109476"] Have you tried a different bullet? Sierra 140gr GK, Hornady 140gr SFB. A different powder ? There has to be a bullet/ powder combo that will give you a consistent group. It come down to consistant barrel vibration. Since my 6.5x06 is a kissing cousin to your PRC , here is what works in it. Bbl., 24" 1/8 twist , Nosler 140gr AB, 54grs Rel 26 , CCI 250 mag, 3075 fps & tiny groups. Also in the same rifle, 121gr Hammer Hunter, 51.5grs IMR 4350, CCI 200 primer, 3238 fps & tiny groups. In 2019 this 121gr Hammer drove completely thru both front shoulders on a very mature elk , range about 80 yds. LET ME KNOW. Another thought. Try letting your bbl " COMPLETELY" cool down ", then shoot another 3 shots right over your first. This will prove if it/s a hot barrel problem. I use 70% rubbing alcohol soaked rag to liberty wipe down my Bbl., over & over till cool. After 4 to 5 min of this the Bbl cools nicely as long as your not out in the sun. Just a thought. You could also cool down your Bbl with alcohol after each shot. This may give you a different perspective. [/QUOTE]
