This post especially for Omega shooters,but will appreciate any comments/help.Have two 50 Omegas.Purchased Two years apart.As most of you know there was a plug design change.The older plugs exit channel is almost flatand the newer one very concave.Should I get a newer one for the older gun so both match?Have any of you done any test/comparison to the two plugs?If so, did you find any differences?As in accuracy,cleaning etc.Also,this could be my immagination but I swear the older plugs primer pocket fire channelseemes to have gotten smaller.Have I not been cleaning properly?Could this be?And one more question.Do any of you have suggestions on Breech Plug maintaince/cleaning with regards to the fire channel?Currently I use 13 and as small a pipe cleaner as I can find.But at times I can see small bits of the pipe cleaners fibers in the channel.Very difficult to remove.Is there a certain tool for this job?Do you oil the channel after cleaning?Have been.Will popping a cap or two clean it out?Really I guess I need some breech plug tips/advice.Sorry for the length,I know this is a lot but dadgummit,this MZL stuff is....well....a lot.Thanks for the help guys.
