A couple of shot primers. Note the lack of soot. These are 209a primers, and are short enough so they leak during ignition in the OEM breech plug. The breech plug used here is BESTILL' plug machined using a hobby lathe to fit Omega rifles to 209a primers.
Note how clean the primer socket is in the Bestill breech plug; showing zero leakage during ignition. This is after about 9 shots. Overall this plug has hundreds, and hundreds of shots through it since being milled to use the Federal 209a primers in Omega rifles.
This plug uses a bushing to provide the flash hole. With hundreds of shots through, the flash hole has grown 0.001"
This plug fits Federal 209a primers, and CCI 209 primers, and the shorter W209 primers in Omega rifles. It has a nice deep primer socket; deeper than OEM plugs; no bulging or leak through using this Bestill plug.
This is about the only breech plug used around here. STS primers cannot be used in this breech plug; they are too short, and would leak soot all over, and make a mess. This is a wonderful breech plug, and is favored around here. This plug cannot be modified to use the STS primers.
The following photo shows a new plug to the set of Omega breech plugs. It is quite innovative.

This plug is gorgeous. It is made of 17-4 stainless as is the Bestill plug, but it is also heat treated, as a result it is quite pretty. This plug is from Woodman Arms, and is completely adjustable for head space. This plug hasn't been shot. This plug can be adjusted to fit any primer in any Omega rifle without machinery. Quite the deal.
First thing done was to adjust the plug to use the 209a primer. The shorter of these primers were crushed 0.004" and longer ones were crushed 0.006". Worked good. Was going to shoot it that way but didn't. Decided to adjust the plug for the STS primers instead. That was easy! Haven't tried it yet, but it looks to be ready.
This plug has a bushing to provide the flash hole. Surprisingly the flash hole is 0.039". That seems unusual. Perhaps the long flame channel balances it out?
The primer socket seems a tad too deep. May be hard for me to get my nails under the rim?
