My first 40 was an Iron Mounted Pennsylvania Flintlock rifle. I believe the unknown builder rifled the bore himself as there are “chatter marks” in the barrel so it fouls terribly. I don’t know whether to try and polish it out or send it to Hoyt and have it made into a 45. The barrel is 42” and a little front-heavy. I’m not sure what the twist is. I don’t think I’ve measured it yet. Rather than cut dovetails for the sights, he made these gawdy bases. He also over-sanded the side plates. I call her “Ugly Betty” (photo 1)!
Last year, I purchased a Chambers Issac Haines 40 from one of our members. It has a 38” swamped barrel (photo 2). The twist is 1-48”. I’ve shot it out to 100 yards. The accuracy is phenomenal! I’m just having a hard time getting used to the full stock. I’ve shot half-stocks with Crescent butt-plates for 35 years. I use it mainly for target shooting. Although, 40 is legal for deer in my state. I’ve played around with powder charges. I usually shoot 40 grains, .395 patched round ball with Bumbling Bear Grease lube (Bear grease and Bee’s wax) from October Country on a .018 Pillow Ticking patch (photo 3). I’ve tried 50 with not-so-good results. 60 grains has the same Point of Impact as 40 but with more foot-pounds of energy (photo 4). Shots 1-3 were 40, 4-6 were 50, and 7-9 were 60.
I also have a 40-caliber English Flintlock pistol made by Hollie Wessel of Lake Shasta, CA, for target work (photo 5). My load is a .395 RB, .018 pre-lubed Pillow Ticking, and 20 grains of 3F BP.
I’m wanting to buy a Neil Fields 40-caliber Vincent Cap-lock rifle (photo 6). This one is basically the same dimensions as a Traditions Crockett. I’m not sure of the twist but most small bores come with 1-48”. Pecatonica River has a kit with a 36” barrel, and a Golcher Percussion lock. I don’t see many Flintlock Vincents. They seem to be like hen’s teeth.
One thing I’ve loved about the 40 besides accuracy is the economy of shooting one; approximately 76 balls and 175 shots to the pound of lead and powder! Plus, Flints locally are $2.50 each. I can get between 80 and 100 shots with a good lock.
