New to the in-line game but exactly how did that happen?
Forget to clean and put away or shoot too much before cleaning?
Nope, never ever forget to clean. I take better care of my muzzleloader/s than I do my wife, I'm ashamed to say. Ask her and she'll agree.
Its a breech plug from an Ultimate Firearms Inc. BP Xpress. What you see on it, is its covered with Permatex Nickle anti-size. From the very beginning, the UF design used a softer steel than the barrel, intentionally. They did not want people removing and reinstalling the breech plugs for fear of damaging the threads. The softer breech plug threads literally wedge themselves into the threaded barrel, making them just about all but impossible to remove. The breech plug itself is a 2 piece product. The outer plug and then the nipple is installed and some type of special welding keeps it securely in place. Although a socket fits over the nipple, the nipple in almost all cases breaks off, thus it requires drilling out, then using an ez-out to remove the remaining threads (as seen in the photo). This is common. Everyone I know who has had a UF breech plug replaced, had to have it drilled and removed like Luke removed mine.
fishhawk2700 can verify.
Also remember, the UF and RUM are able to shoot extremely heavy charges, which production muzzleloaders can not.
This was the third breech plug I've had to replace shooting around 2,000 rounds. This plug was head spaced PERFECT and PRECISELY, but, it also caused me a ton of manual labor with my brass (primer carriers). I used the Nickel anti-seize when I installed the BP, hoping that it would allow me to remove the BP. However, after 8 to 12 or so shots, it was wedged in place and would not come out. Still perfect and precise, but still non-removable.
When Remington purchased the use of the UF breech plug, they did two things, they hardened it so it could be removed, and they changed the TPI. Remington had a ton of head space problems, especially with people using an unapproved propellant, BH209. They finally decided that they would no long warrant BP's if it was known that the owner used BH209.
At that point, some top shooters/builders got together and decided they'd help the Ultimate and Remington Ultimate owners. Arrowhead Sporting Goods (ASG) designed the first new breech plug for the RUM. Next came the UF rifle breech plug. RUM shooters are estatic over the change to the new breech plug. As I understand it from Luke, my BP Xpress will be the first UF Inc. rifle with the newly designed UF BP.
The BP Xpress will ignite any BP or BPS, but BH209 was removed as an approved propellant after gas cut breech plugs became an issue. I gas cut my first breech plug using BH.
After the first replacement, the rifle has only seen T7 as a propellant. The new ASG breech plug will allow the use of BH209 without fear of gas cutting. The plug will now be easily removable.
Luke Horak (ASG), Levi Reed (LR Customs) and Jeff Fisk (Bestill Creations) can replace the breech plugs for either the RUM or the UF Inc. rifles.
