    adding 2" to stock of GPR

    Here we are 2 1/2 months later. I couldn't stand the part of the exposed stock in front of the leather butt cover so I added some braided leather shoe lace to give it a "goodenuff" traditional appearance. I took it to the range and was very pleased with the new length of pull. My face lays down...

    Ballistics for 50 cal

    Thanks for the responses. I have the Lyman book, so I have the stats given there. That Hornady ballistic calculator is great. At first, I just glanced at it because it says that the bullet weight only goes up to 300 grains. After reading the Herb's post I realized it takes my 395 grain. I've...

    Ballistics for 50 cal

    Hello Folks, Is there a book or website at or in which I might find a ballistics chart for a 50 cal muzzle loader (mine's a Lyman) to show powder charges, muzzle velocity, but more important, bullet drop at various ranges? Only have one rifle, and one bullet size; 32 inch barrel,1-32 twist, 395...

    wedge capture?

    My Lyman had the same problem and I TAPPED the tenon. I wondered if it was enough. I couldn't tell the difference by looking. Put everything back together and it was perfect. Just enough tension to "feel right" when I tapped in the wedge. Looking at the picture, I don't think you could get the...

    adding 2" to stock of GPR

    Interesting you should ask that. I've had the sight for a year and a half. Since this recent post, I looked at the shim that was supplied with the sight. The shim is at too much of an angle to properly align the sight. Why? As I inspected the sight, I discovered that the sight is a Lyman 57SML...

    adding 2" to stock of GPR

    I won't know how it really feels till I take it to the range, but as for shouldering and pointing, it feels pretty good. Marv

    adding 2" to stock of GPR

    Hello again, My challenge was to add to the stock, but make it totally reversible. No sanding of the original stock. My intent was make the addition more utilitarian than esthetic, hence the leather coverup. It turned out well enough. If it bugs me too much, I'll have a strip of leather sewn to...

    GP Hunter Loading Problem

    Well, You have my sympathies. I just went through the same trouble with my GP Hunter. The bullet I was casting was .503. The bore of the rifle is .502. The Lyman book says the rifling is supposed to "engrave" the conical as it being loaded. In my humble and not so experienced opinion, that's a...

    adding 2" to stock of GPR

    Hi Folks, I'd like to thank you for your ideas on how to change the sights, but my question was, has anybody tried to lengthen their ML stock? If so, how. As far as proper fit goes, how is it that shooters will shoot a half a day with a Thompson Center Hawken, then switch to a Pennsylvania rifle...

    adding 2" to stock of GPR

    Hi again, I'm only 6'2" with a dress sleeve of 36". What I am trying to accomplish is to get the rear peep small enough to see a small crack of light around the 17AEU hood of the front sight. The aperture is about .041, I don't know if a smaller one is available. I am using the post insert with...

    adding 2" to stock of GPR

    Hello, I have a GPR Hunter that I'm starting to like. I have the Lyman 57 peep sight and in order to get the proper "circle" picture, I need to back up about 1 1/2" to 2". I need to lengthen the stock.I have an idea of how to do it so it could be reversible. I would place a block of wood...

    Plastic bottle powder horn, Dangerous?

    Years ago I used Pyrodex and filled the powder measure from a plastic bottle I had made into a powder horn. Later, I heard that plastic bottles cause static electricity which may spark the powder. So, I stopped using it. Now Goex comes in plastic bottles. Was that a country (urban) myth? Marv

    Lyman GPH shot great with re-sized bullet

    Hi Folks, I finally got the Lee re-sizing kit in .501 diameter for my Lyman 395 grn conical. See Topic #278241. It worked great and it was not too loose for my .502 bore. I'd say it was just right. It slides down easy in a clean bore and has a little too much resistance after about 5 shots...

    FF vs. FFF Triple Seven

    Hodgden's Triple seven powder is supposed to be a very clean powder. That's the direction I want to go for now. The literature says FF used for .50 cal. and larger, and FFF for .50 cal. and smaller. Shooting a .50 cal. 395 grn. conical, what is the practical difference between the two powders...

    Measuring bore size

    Hi, I used the "slide hammer" technique to run a bullet down the barrel about 12 inches and hammer it out again with a steel rod wrapped in duct tape.(put in the barrel first) It worked fine. It appears that the bullet in engaging the rifling perfectly (to me). The first four to six inches of...

    Measuring bore size

    Thanks for the replies. Yeah, generally If you have a .50 cal., you shoot .50 cal bullets.(I'm shooting conicals) I haven't shot it too much, just about a full can of Goex. The problem I had was the .503 bullets from my Lyman mold (#508656 395 grain) I was trying to ram down the barrel. After...

    Measuring bore size

    Hello, Other than "slugging" the barrel, can I measure the bore of my Lyman .50 GP Hunter using a dial caliper just inside the muzzle? If so, is it measured Land to Land, Land to Groove, Or Groove to Groove? Given the width of the lands and grooves, I could accomplish any of the three...

    Casting pure lead Help!

    Thanks for all the responses. I had been holding the mould about an 1/8" to 1/4" from the spout. I also like the idea of enlarging the cutter plate hole. I'll try it all again in a day or so. If that doesn't work, then it's ladle time. Thanks, Marv

    Casting pure lead Help!

    I took the advice of some on another forum, Smokepole, and got some 99.99% pure lead and an iron bullet mould. It's a Lyman .50 395 grn. #508656. I have a Lee production pot. After about 150 bullets, I still can't get a crisp, full casting. All the bullets look like the mould or metal is cold...
