I had my single shot 12 bore Jeffery rebarreled with a new rifle barrel. The old shotgun barrel would not pass proof and had a hole ground into it so that it could be auctioned legally in England as a "stock and action only". I paid 45 pounds for it. Bought a new hastings shotgun barrel and had it monoblocked, (sleeved), into the action and sights put on. It weighs 5lbs 8ozs. And considering the action, will be for lower pressure loads only. Chambered for 2 3/4". Should be a handy little rifle up here. I loaded up some rounds a few days ago with different bullets. The best was this one weighing at 816 grs but it shot from 725 up to the 816 almost the same. Target was at 40 yds standing offhand. I could barely see the front sight. I need to do something about that. 4.25" spread. I've now named the rifle. "Mule" as it kicks like one.
