I just put together my second 30 PPC rifle using a Ruger #1 that I had a buddy install a heavy Hart barrel with 1-14 twist--22inches long. This barrel on another gun put 5 shots into .058" center to center @ 100 yds. On a normal day good groups run .250"-.350". I was shooting up some old mediocre ammo with a friends 12 yr old son. From a rest he hit a steel pig at 200yds 18 out of 20 times. The load--a RCBS 130 gr gas check bullet powered by 6.0 grs of Titegroup. Most accurate load to date is 125 gr Berger/27.0 grs 2015/Fed 210 gold medal. This gun is really fun to shoot!
