Do the 777 specific primers have enough fire to ignite BH209 consistently?

I know they were supposedly designed with a little less heat for reducing the crud ring that 777 is said to create.

Right now all I have is the Winchester 777 primers and am wanting to work up a load with BH 209.

What say the resident experts?

No, they are the weakest primer you can buy.

10-4. Kind of what I was thinking.

BH web info used to specifically recommend against any primer but 209 shotgun. I’m thinking the breech plug sleeves that take a large rifle or large rifle magnum primer should be the bee’s knees. Tired of drilling out 209 crud from the flash channel.

Yesterday it was 3 shots max before I couldn't see through the flash hole in the breech plug.

I need to keep a torch tip cleaner with me.

I've had good results with Win 209 and CCI magnums with Blackhorn. Had a bunch of misfires using Remington and standard CCI 209 primers.

If you are shooting a CVA, the 209 breech plug actually helps a lot too, especially in cold weather.

I have the breech plug, just waiting to get some regular 209 primers and not the 777 primers I have.

Can't imagine any 209 NOT igniting BH209. Maybe I've been lucky.

I couldn't find 209s last year.... I did find a VariFlame large rifle primer breech plug. The sales pitch made sense.


I run CCI 250s... haven't had a failure yet. Knock on wood.


I believe 209s are way more powerful than 250s.


Clean up and fouling is minimal too.

250 is a large rifle mag primer, hotter than a 209 by miles.

For some reason I thought 209s were more powerful.
