MLN1963, I bought it at Sportsmans Guide. They have raised the price since then.

CVA claims the ignition is 5 times higher but I think the reason there was no crud ring was because the ignition is weaker than a 209 primer. I've never seen a report on a Electra where the gun consistently and reliably ignited BH209. I do not have any BH209 to try.

I used a standard 9 volt Duracell. It was probably an old battery. CVA does recommend lithium batteries for cold weather.

Never tried to remove the white splatter. Kinda like it. The SG price is pretty good I would jump on it if you really want one,
