I just had a thought as I read Sabotloader's report on his Renington Bolt Conversion. He mentioned how he was going to modify the head space between his bolt and T7 Primers, as some people may not fully tighten there Breech Plugs as he does tighten his, thus allowing for the small difference in space between the two.
Here's my question.....I am one of the one's that just (finger tighten) my BP. A long time ago I had a bad experience where I had the BP too tight and I had a heck of a time getting it off, when I did I from then on just finger tightened it so this would never happen again.
If one finger tightens there BP does this allow more blow back as I assume it would? Also when one get's blow back form the BP does the blow back cause a loss in the full effects of the powder charge? Would you lose velocity from the loss of blow back?
Also are there any other effects on the ML from blow back besides just more of a mess to clean?
