i have built 5 underhammers the first was a deer creek kit but the other 4 were from Pecatonica. Dick Greensides is a good and honest man to deal with and goes out of his way to help customers and every time i have seen hi at a shoot hes shooting an underhammer.
both style of kits are well made and easy to build and inexpensive. i would reccomend you order a extra ramrod pipe 1 works but 2 is better. also get any barrel work done if you dont feel confident doing it yourself. his standerd grade wood is great, i have 2 stocks maple and 2 walnut with nice figure and no issues. the hardest thing to do on the kit is fitting the butt plate its real easy to remove to much wood but i am getting better at it.
rifle #2 36" .45 barrel H&A action maple. this is my favorite all purpose woods rifle and offhand target rifle with click adjustable steel rear sight. off the bench at 50 yards its a 1" rifle with roundball. now this winter i have been experminting with minies and have gotten 1.25" group once. great for shooting in cold weather.
rifle #3 36" .36 barrel H&A action walnut. my squirrel rifle i built to replace #1 i sold years ago. very accurate, with click adjust rear sight. used this rifle all during 2015 summer league at local club, #2 was on sideline for fixing. .36 shot during league from 15 yards to 100 for the 100 yard gong it helps to have someone spot for your hit sometimes you dont always hear the clang.
rifle #4 34" .45 1" across the flats Allen Action maple. this is my bullet rifle for 200 yard plus shooting with a modern mildot scope. with a 90gr charge launching 450 gr bullets i can easily from a rest make hits from 200-300 yards and a few times once at 600.
rifle #5 what i am building now 38" .40 1" across the flats Allen action walnut. this will be my roundball bench rifle for 25-100 yards. this will have apeature sights i bought an old german rear aperature for this rifle. also i plan on trying cast .40 s&w bullets to see what happens kind of like the old picket rifle
rifle #6 future project Allen action walnut 12" pistol barrel .54? plan on building a short rifle like the one shown on cap an ball youtube channel but underhammer not flintlock should make for a great hikeing rifle for plinking and protection from cattails, rotten stumps and pot growers.
these are my rifles. the only underhammers i dont like are those i dont have. i wish pecatonica would come out with a complete bilinghurst rifle kit.
