Power stem breech plug question?

Power stem breech plug question?

Postby rockram » April 6th, 2013, 10:08 am

I am new to muzzle loaders. I traded into a Knight Disc Extreme. LOVE!!! this weapon.
With the Disc I got 1/2 box of pyrodex pellets and 1/2 box of triple 7 pellets.
A buddy uses loose Triple 7 and is happy with that. So I was thinking I would try loose once my pellets run out. It's cheaper and I like the ability to adjust amount of powder.

I was doing some research, and came across the Power stem breech plug. However I couldn't find anything on preformance. I understand the concept but is it worth the money or is it just a bottle of snake oil?

Thanks for any assistance

There is a small performance gain when using large loads of 777....like 130gr+ loads. The Powerstem plug is only offered in a FPJ and the stem does not work with BH209.

IMO the bare primer plug is a better investment. It works fine with BH209 or 777 and cleanup is a little easier.

If you use the powerstem you can not use the pellets. The powerstem will give you an increase in accuracy,velocity and energy. It provides a more efficient powder burn with loose powder, but you must be easy when cleaning and not bend the powerstem.

Although I've never used the power stem I definately agree with the above. I recently purchased a Disc Extreme and immediately converted it to use the bare primer plug. It now shoots incredibly clean and ignites BH209 without fail. BH209 is the hardest powder to ignite so it should work with all the other powders as well. Plus you never need to buy and use the red plastic jackets again.

The bare 209 primer conversion kit is 41.99 which is a bit more than the power stem at 21.99. But I think the advantages are worth the extra $20 - UNLESS you are sold on shooting loose 777 powder and the power stem breach plug is signficantly superior to the bare primer breach plug for that purpose. I don't know the answer to that question.

Like others have posted, I would move over to the 'Lehigh stlye' plug & you will good for any powder or pellet. I would just use B209 though. That's the way to get max performance out of your Knight.

777 is absolutely obsolete with BH209 on the market.

I've shot only BH209 for three years or so and will NEVER shoot another 777 load. Period.

I am heavily considering an Ultra Lite set up with no plastic jacket for this year. Incredible rifle.

777 is a very good powder for allot of shooters, personally I love Blackhorn 209 with every 1 of my Knights. I also love the bare primer breach plug. BodyCamp13, you will love the Ultra Lite.
