Today was 2ºs with a windchill of -15 to -25 degrees, but it was not snowing. The wind was blowing out of the north, and it was COLD!!!
I wanted to shoot my 21" Green Mountain Long Range Hunter Barrel with the 1-28 twist. This is a flintlock barrel mounted in my T/C Hawkins Rifle. I swabbed between all shots with pure isopropyl alcohol. I loaded 90 grains of Goex 3f and a .430 300 grain XTP in a Harvester Crushed Rib Sabot.
I fired shot #1 and wondered why it was so far to the left. Checking the rear sight I noticed it was not centered exactly. So I centered the rear sight. I then shot #2-#5 and was more then pleased with the accuracy of the rifle so far. To then check if it was me or the sights, I adjusted my POA and fired #6 & #7. About this time, my camera battery went dead.
I then decided to try some .503 460 grain Bull Shop Conicals. I loaded 70 grains of Goex 3f without a wad. I fired three of them. And they grouped well. I would have shot more but could no longer feel my toes and fingers so I decided to call it a day and wait for better weather.
Over all I think this barrel will be a good one. With 90 grains of powder there is no recoil, but then I had on a Parka to stay warm.
