    School me in an underhammer rifles


    I've been mulling over the idea of building a underhammer from the pectonia river kit (http://www.longrifles-pr.com/underhammer.shtml), but I had a few questions I was hoping to get answers to before I make I take the jump:

    -Is there anything especially different or weird about and hunting and shooting with an underhammer as opposed to a sidelock I should know before purchasing? I've read some stuff about burning out nipples, needing specialized nipples, gunk blocking the nipple after swabbing, etc.

    -Is there a half cock on the rifle?

    -I am in love with my Lyman 57sml peepsight. Has anyone mounted one to one of these rifles?

    -I think I am a generally mechanically competent individual, but only posses hand tools and have never put a rifle together before. Anyone with experience with this kit want to weigh in on it's difficulty to put together?

    Thanks! I really appreciate any insight!

    Mine is a original H+A with a few up grades thanks to johnson 1942 ,aside from wood note the magspark ignition (209 primer) .No burn on bare forearm and never a lost cap , bonus its quite moisture resistant . Mine accounts for most all my squirrel needs (wings) Please note the 1/2 cock position ! Ed Click image for larger version.

    If you experience nipple burn out, switch to platinum lined or treso ampco nipples. Mine was damaged in the store fire so I only replaced the shoulder stock. (I have multiple caliber barrels I'm having converted to UH profile. Mine uses a tapered pin.) So I dont want a fore end. Half cock is too close to the nipple to use a cap holder. A nipple pick is a good idea.

    i have been shooting underhammers since 95. i use hotshot nipples and real black powder. never had a problem with nipple burnout also so if you use th flash cup you will not get burnt on the arm. never had a problem with lossing caps.

    I put together one of the Pecatonica kits and it was a little more involved than say, a TC or Traditions kit but still pretty straight forward. I have a Lyman 57 mounted on the flats of one of mine.

    I put mine together from a Pecatonica kit. It was fun and not too bad. I started with a .36 barrel. It is great for targets and small game.

    It has a half cock. Never lost a cap. I always remove the nipple when cleaning so no clogging. Just a fun light weight rifle.

    I have bought and working on fitting an 20ga barrel for my underhammer. It groups well. Looking forward to upland bird hunting.

    I have an original H & A in 45 cal and one of the H & A models that Deer Creek made years ago - I love under hammers.

    In regards to differences between a sidekick and under hammer - my .36 has taken lots of critters. With the nipple on the underside flat - just make sure that you have tight fitting caps for the nipple - if not, they can be an issue falling off while in the field or target shooting - all common sense.

    Make sure you have a nipple that is the correct size for you barrel size - i.e. the threaded portion should screw in to the barrel so that the bottom of the nipple is more or less "even with the bore wall. Track of the Wolf offers a variety of nipples for under hammers so that you can get one that is correct to the barrel size.

    Mine all have a half-cock position - i.e. safety notch.

    It's really too bad that someone isn't making these rifles anymore - but Pecatonica certainly has everything you need to make one and the work to do it would be minimal compared to making a standard sidekick rifle.

    The "Plus" is that you can also have the capability of having several barrels in different calibers - or smoothbore - that can easily be changed out without a problem.

    The H & A style action is a very simple action with minimum parts. Very dependable as you flash is going directly into the powder load. Add plus is that an under hammer is easily adaptable to either lefties or righties. Once you have one and shoot it, it just kind of grows on you - enjoy and have fun!

    I make under hammers occasionally but I can't compete with the price from Pecatonica. Their kits are the same as the later H&A with the three set screws to hold the barrel to the action. The only improvement that should be done is to grind the half cock down some so it won't catch the hammer when firing. I have had several come in over the years with broken triggers caused by them catching the half cock. When I first started shooting an H&A I got some bad burns from a burned out nipple. I have not had a problem with good nipples.

    I Hate underhammers... Back in about 1976 we had this sharp eyed kid buy a cheap H and A underhammer and join our club. Soon this kid with a $40 rifle was outshooting al of us some who were shooting $500 dollar custom guns. That little stubby cheap underhammer just shot like a house afire. Out to the 50 yard line we just couldn't beat him. Finally he was convinced to buy a GOOD gun and he never shot the GOOD muzzleloader a well as that cheap old H and A. Now his grandson is shooting that darn gun but now I have an excuse!
