just curious if anyone has ever tried any of the new ideas of using pistol brass for a primer. the advantages are supposed to be mostly no blowback, but also an increase of accuracy since the blast from the small pistol primer is much smaller than that of the 209. i've seen people use 22 hornet cases cut down, 25 acp and also the S&W 32 short.

I know I'll catch some flak here, but there are some safety concerns here that need to be pointed out. With so many different types of in-line muzzleloaders being manufactured today, and never knowing the quality and metalurgy, especially in some foreign made rifles, the potential for injury is high. The trend is to higher pressures and higher velocities and the vast choice of different powders and projectiles is mind boggling. There are no SAAMI standards here, and as far as I know Lyman has done more testing and data publishing than anyone - but the rapidly changing technology has even left their fine work behind.

Last year my neighbor had his percussion sidelock blow up in his face. He had merely substituted his friends in-line load in his traditional type rifle. Presently on the Michigan Sportsman's forum there is a posting about a young boy who suffered injury to his hand when his in-line rifle blew up - smokeless powder was suspected, but the truecause is unknown. Because of all the loading choices available today, the in-line rifle probably has the greatest potential to cause injury than any other type of firearm. Virtually any kind of powder and projectle can be stuffed down the barrel and dangerously high pressures are possible. I don't know how well some in-line rifles protect the shooter's face in case of a blown primer. I don't want to find out the hard way either.

Taking chances with components is not worth the risk of serious injury. Experiments are best left to the guys in the lab. I apologize for throwing a damp rag on your posting.

dont appologize, i was hoping to have a good discussion here and you make a very valid point. much like you, i think a lot of the expiramenting should be left to the guys who truely know what they are doing, experienced gunsmiths and such. i was only wondering if people are actually buying into this stuff or if its just another "gimmic" for some companies to grab another dollar. I've found one site who sells these breech plugs pre-modified with a handful of the brass for almost $60. the last breechplug i bought was $11. seems to me these people are selling the idea and not the product. anyways, im glad you replied and i hope others do too.

Since you labeled this thread ".336 primer" you must have read "Doc" White's research and article on the .32 S&W breech plug he developed for the White Thunderbolt. How much more info do you need? Doc's pretty thorough. I think the use of a cartridge case as the primer holder makes sence in both therory and practice. One of the reasons I "disvested" myself of Knight rifles was the filthy back blast that gets by the plastic primer holders. My Savage MLI and MLII, by design, have zero blow-back. My T/C Omega X7 with a .25 ACP converted breech plug now has zero blow-back due to the brass case doing what it was designed to do in a cartridge gun....... seal the chamber. If White ever markets the .336 breech plug, I will install one in my Thunderbolt ASAP. Heard of Ultimate Firearms? They market a rifle that uses a .45 case to hold the primer and get 2400 fps with a 300 gr bullet and 200 grains Pyrodex with no blow-back. Point is, it works as advertised concerning blow-back. I think that in itself is worth it. The only down side i see is the extra time involved in depriming and priming the cases. Just my views
