Have a question that some leaned people here may like to comment and provide opinion please.
Take the example of the Postell cast which most are familiar with - it has a driving (or compression) ring at the front of the projectile before the lube grooves...I know some loaders who use that to seat the projectile to - in other words they sit the projectile deep enough that the case lip covers that band and is crimped over it in their final stage of loading...thus ending up with a slightly shorter load and a tighter seating......others including myself, usually seat the projectile to that band so the brass lip sits against it, not over it.
Not wanting to open a discussion as to seating depths as that's entirely different to what I am asking
Now I can imagine there are pros and cons for either method and it would very much depend on the chamber specifics as to whether they will chamber that way - some rifles I have won't because I've tried it - the outside diameter is too great once the brass is over that lip, obviously tight chambers specs but others will
Black powder is not an exact science and pretty forgiving in a lot of things but is the design of that projectile and other similar ones with such a rim, made specifically to act as seal and if so should it be enclosed by the case? Equally, I'd imagine all sort of issues may occur loading them that way but those I know who do it, swear by it and won't change.......my view being it's their decision and what works best for them but aside from some cases not chambering , I could not tell any difference one way or t'other as to accuracy, fouling or recoil etc???.
Any clues or suggestions to open a discussion on it, opinions etc?...I would be interested to hear what others think........thanks.....Lee
