Are my Primers Garbage ??

[Deernewbie]

Hi All,

new to muzzleloading purchased 100 Winchester 209 777 muzzleloading primers. upon further research it seems these are the weakest ones I could own.

for detail I have a CVA Accura MRX .45cal I intend to shoot BH209 and 200gn Hornady SST

from what I've gathered I would be better off with a "hotter" primer like CCI 209m. However, it seems there is a shortage of all things 209 primer

Are using these weak primers likely to cause a noticeable difference in safety and performance? or am I overstating this?

would I be better off finding a variflame adapter to use rifle primers? although seems a bit extreme considering I have yet to shoot the rifle

They might be ok in warm weather. I certainly would not depend on them lighting bh209 in cold temps. Try them and see how ignition is. If you get a chance to grab some different primers, anything NOT muzzleloader specific, grab them. Look in the shot shell reloading area of stores, anything there will be best.

I also have some triple 7 3F. would this be easier to ignite due to smaller particle size? I just don't know if it is safe for my rifle or where to start with load development

 

[ElDiablo]

Yes, 777 primers were made for 777 powder. BH209 requires a hotter primer for reliable ignition.

I sure hope any 209 primer will ignite T7 because my RWS musket caps seem to just fine.

Caps are better with 777, IMO - less crud ring. But, yes, any 209 will ignite it - the hotter the primer, the more crud.

How about 5-10 grains of T7 down the barrel first. To help ignition that is.

…or real black.

theoretically.. this is pretty genius.
ever tried it?

 

[ElDiablo]

Lots if us have used (or still use) an igniter charge. I use 5-10 grV black with 85 grV 777 in my shotgun. Better ignition.

Black powder is used as as an ignighter charge for bags of powder used in ship's guns

 

[BuckDoeHunter]

Which breech plug do you have? Do newer CVA muzzleloaders come with the loose powder breech plug or still the flat faced plug for pellets? If you don't have the loose powder plug, you need to get one to reliably shoot BH209.

Load the 777 fffg ... in start with 50gr... try 60/70/80... thats my loads with a 50 with 777.... could probably shoot 100gr 777 safely. But not needed im my opinion at expected ranges....

So, your new primers are not garbage. I never have done this but you see other do regularly. This is the right place to ask MZ questions. If there is a solution you should be able find it here. May have to wait a day or a week but the answer is out there.

And artillery!

What are everyone’s thoughts on this primer designed for skeet and trap loads? I use with 777 pellets I get an annoying crud ring. With 777 powder I still get the crud but 1/2 as bad. Are these hotter than most?

First lose the muzzle loading primers. They are deliberately weak to avoid lifting the bullet off the powder before the main charge goes off. They suck with BP substitutes (particularly BH209) and don't like sub 20 degree temps. Second, make sure you have approximately a .003" crush on your primers when you lock up the action to direct 100% primer fire to the charge. This will give you instant ignition and prevent hang fires in cold weather. A fire primer should be shiny on the sides with no carbon anywhere except the nose pointing towards the powder.

Yes all the time, its called duplexing ! Those 777 primers should have no trouble with any blk. or sub blk. powder. I have never tried the B-horn as the cost not worth it to me.

The Rem 209s are lower powered than some of the other options.
