Sabotloader indicated he believes an OAL with the W209 in place of 1.310" would be about right. What do you think?
Remember I was taking a shot in the dark, because i do not have a CVA in the house, nor do I plan to, but from the inforamtion that you have given and some of the information given by MD, + one other thing I think you have to factor in... not every gun is built the same... that is where the 1.310 imerged. I think you need to be a little long (deep) vs. shallow just to get the gun closed. Yes - NO?
One thing I would have to re-consider is if you supplied MD with a 1.300 and it seems to be OK with him and your thought was it should be 1.305... which he felt was to loose.... The 1.310 would probably be to long.... Without a model gun to work with it is all a guess from this end...
Another question for you Ron... Are your primer pockets tapered? From wide at the month to more narrow as you go down the walls? I think we have that this is also an advantage to get blow back free as well as relieving blow back pressure on the nose of the primer.
You are right theory is theory, but there is some science and math in there also when you consider 'volume' of a space the time it takes to fill that space. Believe me... I am not smart enough to figure the theory stuff out, I just try it an make a back yard evaluation from there and from what I have seen in the last year - it all makes a difference.
Initially this new BP design was done with a lot thought, calculating, and experimenting to come up with the BP that would function the best in all environments.
and again I just shoot it.
