Encore Bulging Primers w BH209

[Chris Champion]

Guys,

I know very little about Encores. I have an uncle that has an encore that bulges the cup on Fed209A primers ever since he tried to shoot BH209. He's tried 90 & 100g charges w/ 250g SW & Harvester EZ load sabots. This is an older Encore with the original style breech plug. To my knowledge he has kept up on the proper maintenance of this gun and recently drilled out the carbon build up with an 1/8" drill bit. This gun has probably not been shot over 400 times with mostly T7 & Pyrodex. His groups with the above load combos have been very erratic. The same load shoots MOA out to 200 yds in my dad's Omega with the same style breech plug.

Now when I hear bulged primers I think excessive pressure but I can't imagine that 100g BH209 being the problem. Other than trying a different lot or brand of primer is there anything else that we should be looking for. He's asked me for help and since I don't know much about Encores I thought I'd check in with you guys.

Thanks!!

Chris, I'd try a new plug. It's possiable the vent hole might be too big.

Probably a stupid question but any chance your dad's omega bp will fit your uncle's encore just to see?

Thanks Al. That's kind of where we were leaning next. My dad has a new extra plug for his Omega that he can let him try.

Chris, I have a domed BP that came of a 50 cal dics elite. I will be happy to send it to you if it will fit. Rusty

range...Not a stupid question at all and in fact the breech plugs are the same. My dad is going to lend his brother the breech plug to try out this weekend.

I agree with the thought that the BP's orifice has likely gotten too large. They do wear out.
