All, Thanks for the replies! I still think I would measure standard deviation as a population instead of a sample, but I like dialog... thanks again! Scott

Why does my chronograph calculate standard deviation as a sample and not as a population? I get that the recorded shots are a sample of all the rounds of that lot that could be fired, but I'm really only interested in the shots that were fired. Looking forward to some knowledge

I'm going with grip-tape for the time being... but I have contacted the builder to determine cost/time to convert to a Serendipity.

Dude, you know I'm first in line

I'm looking for a broader, higher grip surface my weak-hand thumb. I've shot a couple of open guns that had a c-more Serendipity which has legs on both sides of the frame. The right leg gives a broader, higher grip surface for the weak-hand thumb than just the frame below the slide. And, while i'm going to consider a thumb-rest, I'm more likely to have the single-sided mount changed out for a Serendipity.

There you go, that's what I'm talking about Thanks!

I'm new to open and shooting a shorty with a single-sided C-More mount. After much fiddling around I've decided that I would prefer a Serendipity with mounting brackets on both sides because the only place for my weak-hand (right) thumb is the frame and that's just not large enough. The frame is not drilled on the right-side so anything will require a gunsmith to drill and tap the frame. I'm thinking my options are having a Serendipity installed or some sort of thumb-rest. Looking forward to any thoughts/feedback/comments before I ship it off

Liked it. Don't think it's all that profound. The twist was interesting, but I don't know that it added much meaning.

It was a fun stage... the poppers really made people look at it twice.

Thanks for the additional info.. I am going to look into the lapping... some of the High Power / Service Rifle guys I know swear by using Tubb's Final Finish http://www.davidtubb.com/finalfinish.html which is a lapping system. Thanks!

Thanks to both for the replies. Yep, it shoots fine; more accurate than I am. I'll just enjoy shooting it. Thanks, Scott

Evening everyone. It's been a while since I posted here, hope everyone is doing well. On to my question... while cleaning my 625-3, I noticed a faint ring inside the barrel, about where the frame ends. Unscientific testing seems to indicate the ring is right at the barrel/frame joint. It's faint, but definitely noticeable. I've attempted to take some photos of the ring. Pics here I would appreciate any insight... I've never had a squib in this gun and don't recall the ring always being there. Thanks ahead of time, Scott

What stage were you working?

My antique SVI runs the tj brass fine but my shellplate on my 550 won't hold the brass correctly. It slips out on the sizing downstroke.

There is definitely a lot of gun handling.
