8 Bore Boxlock Rifle

Colin Stolzer, who owns Stolzer & Son’s Gunsmithing, emailed me photos of a custom 8 Bore Boxlock muzzleloader he was recently build for a client. It is a true work of art.

Click to expand the photos (the small thumbnails do not do it justice):


8 Bore (.835″) 1:104 twist Octagon to wedding band transition then straight tapered round to the muzzle.
Jeff Tanner Ball Mould (.805″).

The finished rifle weighs right at 11 pounds.

The Action is a Pete Allan Boxlock Casting, it is representative of the 1860’s Edwin Wesson Boxlocks. The metal finish is rust blued.

The Ramrod is Rosewood w/ a steel button on one end and a threaded steel tip on the other for accessories.

It has a full length underrib to add a little weight.

The Stock is rock maple, stained with a dark walnut stain and then oil finished and then waxed to a sheen.

The forearms has an ebony tip, all the pipes, underrib, front sight and sight base were custom made in my shop.

The action was also reshaped, and the original triggerguard was removed and replace with the more elegant and classic one in the finished pictures.

The butt plate is a wide English style plate. The checkering is flattop.




I asked Colin to email me some photos to give a sense of scale to large bore size.


8 bore balls. These would weight 875 grains is they were pure lead.

Many thanks to Colin for emailing me this photos. If you are wanting a custom muzzleloader designed I am sure Colin could make you one. His contact info is on his website.

    Neat, but K.O.B.E. (Kills On Both Ends).

  • Hmm…would a bayonet mount, pistol grip and flash-kaboom suppressor transform this beauty into an assault rifle? Would it also need to be painted black?

    • Broadsword, no – just black paint 😉

      Matt, it is for men who are more manly than I.

    RE: picture above, that should be “A nickel IN the barrel.”

    An awesome representation of the master craftsman’s art.

    ??????? I don’t get the logic with this I could not find cost but it would have to be astronomical.
    just get a 500 A square bet it’s cheaper you can shoot it past 60yds and it will have much more energy.
    there are also many Smokeless 70+ cal rounds but there is no reason to exceed 50cal.
    50bmg out of mil spec barrel puts 12000 energy a shot, it will go thru and thru any living thing on this planet.
    I have personally shot a 50cal black powder carbine no recoil at all did little or no impact damage and was low at 75yds.
    the round I shot cost in excess of $3 each, I can get 50rds of .44 mag for 39.99 and it does more damage.

  • Matt Groom,
    Thank You.
    It really doesn’t kill on both ends, it has about the same felt recoil as my .458 Win Mag, the difference is the 8 Bore is a hard shove , were as the .458WM is a sharp kick.

    B Woodman,
    “RE: picture above, that should be “A nickel IN the barrel.””

    The picture of the Nickel was taken while it was still being built, before it was turned and crowned, in case you also happened to notice the chips at the muzzle.

    “An awesome representation of the master craftsman’s art.”
    Thank you that’s very kind, but I’m not even close to being a master.

    josh j,
    I guess my first answer should be that logic has nothing to do with owning fine hand made firearms. A Holland and Holland best grade royal side by side costs as much as a house and only holds two round, and for the same price I could by 100 nice bolt action rifles, but you know what, I would take the Holland and Holland every time. Because the Best Grade Side x Side has nostalgia, and a type of refinement that I can’t get any place else.
    As to cost, you could have just emailed me and ask and I would have quoted you the price, instead you are assuming it’s astronomical. In fact it is less than the cost of most of the 50BMG’s.
    500 A-square isn’t likely to be cheaper to shoot, factory ammo is $90 – $115 USD a box of 20. That averages $5.00 a shot. I can shoot the 8 Bore for about $0.65 per shot. It shoots just fine past 100 yards, it was sighted in at 60 yards at the customers request. 60 Yards is actually a long shot for the type of hunting that these types of big bores are used for. Typical shots on large dangerous game, such as elephants are typically taken at less than 50 yards.
    As to the use of a 50BMG to hunt, I won’t disagree that it will probably go through and through any animal, but through and through is not always the desired result. Sometimes the desired result is produced with more mass at less speed, and then you also have the problem of carrying the 30 pound 50BMG through the bush of Africa and being able to shoulder it and shoot it on the swing if necessary. Where as a custom made 11 pound 8 Bore that is perfectly fitted for the owner and swings like a fine shotgun is much easier to pack and use.
    As to the .50 Carbine you shot, I can’t attest for your results, but I hunt muzzleloading season with a .50 cal Side by Side Muzzleloader every year and last year I shot through and through both shoulders of my whitetail and decimated both lungs, and the shot cost me about 45 cents. Without knowing more about your specific experience with shooting Muzzleloaders, I would say something doesn’t sound right to me.

    Thanks for the compliments and comments.

    ??? what I shot was not a muzzle loader it was a black powder cartridge rifle, I like cowboy action stuff but not black powder too much cleaning.
    I also prefer to shoot farther than 50yds unless handgun hunting, that is very exciting at that range but there are too many stories of the venerable .458 mag failing to stop African dangerous game.
    did not mean to offend it does look nice and if you got the money it’s your right to spend it on what you want.

    I just stumbled upon this site and thought you may be interested in a short story. I met Pete in 1975 while deer hunting in Whitewater St. Park in Minnesota. I had been planning on building a rifle from scratch and got some great pointers from him. He frowned when I told him I was a wood carver and wanted to do a fancy rifle. He hated them. He did however tell me when it was time to get the parts to come and see him at his home and he would hand pick my hardware. I ended up with the best shooting 50 I have ever seen. All I can say is Thanks Pete.
