    Does anyone know if it is safe to use a Mag Spark 209 Primer Adapter conversion for sidelocks on a Lyman .54 cal GPR. I contacted Lyman, but they won't comment on any product that they don't sell.

    Cold browning Lyman .54 GPR Barrel

    bamaboy I have the same problem with my fixed site, it's a bit on the small side. How long did it take for Lyman to send you the right size site?

    Cold browning Lyman .54 GPR Barrel

    Thanks Zonie for confirming my thoughts on the steel wool. Since the LMF product is both a Barrel Brown & Degreaser, would any wax on the steel wool really matter?

    Cold browning Lyman .54 GPR Barrel

    Following the LMF instructions I've sanded the barrel down using 400 then 800 grit w/d paper. I then used the Birchwood Casey blue and rust remover to strip the bluing. The instructions for the Birchwood Casey blue and rust remover recommend using steel wool to "polish" the metal. I can see...

    Cold browning Lyman .54 GPR Barrel

    Thanks bamaboy the bolt in a cartridge case trick worked like a charm. I've got a question about GPR sights, I've read on a number of sites that with the adjustable sight the GPR shot low (I think by about 6") and as a result the front sight had to be filed down quite a bit. Since the height of...

    Cold browning Lyman .54 GPR Barrel

    Thanks Cowpoke, haven't had my GPR long and didn't have it in front of me. In my mind, I was picturing it as part of the butt plate, then I remembered the user guide had an exploded view. Are there specialized punches that small in diameter as to not leave a large hole in the stock,or do you pry...

    Cold browning Lyman .54 GPR Barrel

    I just fired it for the first time on Saturday, so it still has the modern sight. Did you have to do much filing on the fixed site? I had used 1000 grt wet dry to sound out the scratches, is that going to cause a problem? ill the rest of the barrel brown differently, causing an uneven look. Also...

    Cold browning Lyman .54 GPR Barrel

    I have a Lyman GPR .54 cal and want to brown the barrel and tang. I have Birchwood Casey blue and rust remover and will be using Laurel Mountain Forge Barrel Brown & Degreaser. The gun came with a 3" area of the barrel in front and behind the rear site that had fine scratches which I want to...

    Thanks for the feedback everyone. The .54 was what I was originally leaning towards getting, so I'll stick with that choice.

    I'm about to order my first ML and have decided on the Lyman Great Plains Percussion Rifle in either the .50 or .54 cal. While doing my research I read on a couple of sites, where the recoil of a .54 BP was being discussed, that some posters actually mentioned the 30-06 recoil in the same...
