I found a interesting article today about the standard breech plug and Blackhorn 209. I was reading up on modifying the standard plug. There are several articles about the modifying. I found where someone had just drilled the flash hole to .035 and used the BP for BH209.
Then I found a article/post made by a guy who said at the time he has shot over 150 containers ofBH209.
He found that by using the standard breech plug (unmodified) with BH209 was perfectly okay. He said by drilling out the flash hole to .035 you basically take a new BP and make it a old worn out one. He suggested using standard 209 primers over the hotter CCI 209 primer.
He has used the standard BP in negative temperatures while hunting and load development with zero problems.
I’m going to give the standard breech plug a go with BH 209 and see what shakes out.
