Interesting thing is with most of the powders, the issue starts around .2 grains from starting. Not looking for speed as much as accuracy. Makes me wonder how they can be used in the .32 H&R and .327 Federal I had seen. I'll play around with some other powders. The WST Ignatz mentioned sounds interesting....

Weirdest thing today, I made up some loads in .32 S&W Long using the Speer 98gr. LHBWC bullets. Used W231, Titegroup, Red Dot and Bullseye powders with Starline brass and CCI primers. Starting grains worked all right but as the charge increased, I noticed extra bullet holes in the target. I was shooting 5 round groups at 25 yards and ending up with a pattern and not a group. Put a target at 10 yards and fired 5 rounds. I watched two bullet holes appear with a single shot fired. I think the bullet is separating at the skirt. It sucks because I wanted a nice target load. Revolver used is a Ruger GP100 in .327 Federal.

My tools came in. Crane is fine. The extractor rod has .004" run out. I found the spring in the thumb piece was short and replaced it. That fixed the binding issue. The timing is ever so slightly off on the same chambers. I am currently fitting a new hand to fix the timing. I bought this gun as used. The timing was fine in single action. Didn't notice the issue before with the 1 ton double action trigger pull. I had polished the rebound slide, changed out the rebound spring and installed an APEX hammer. That was when I noticed problems. Thanks.

I don't, but Brownell's will... I created a reference point along the extractor rod and I do see wobble. Don't know by how much as I don't have a tool to measure it... Yet....

I removed parts in play and put the cylinder back in. I spun it and found it will not spin freely. The chambers in question are binding more so. Opening the cylinder when the chambers in question are at the top or to the right is very difficult. put them down or to the left and the cylinder opens. I am starting to see wear marks on the frame where the ratchets meet (this is a 627-5 but for all intents and purposes a new gun). Applying a black marker on the ratchets shows some high spots.

I have a 627 in which I have been working on. I currently have the trigger weight at ~5 lbs. As I go over my work, I notice that 4 chambers are harder to pull than the others on the other side of the cylinder. 3 of these 4 are slightly out of time (1, skip, 3 then 4). I didn't have this issue with the heavy factory weight, and no, I did not touch the inside or too if the hand, nor the ratchets. This is more pronounced when I ease the trigger. When I hammer through the trigger, it seems to lock in all 8. Everything functions fine with the cylinder out. Even though I can't visually see it, I am thinking the ejector rod is bent or something is wrong with the yolk and binding the cylinder, causing the issue. Am I thinking correctly?

I've been lurking here for several months. I tend to read more than post. However, thought I'd make my presence known. I've been competing for about three years; mostly local matches as work tends to get in the way. Picked up the revolver again last fall and love it's accuracy. I bought a Ruger GP100 with a red dot sight. It was used but the guy I bought it from was one of those who buys guns, fires less than a box, then sells it for something else. I put a spring kit in it which gave it about 8lbs. double action. Trying to learn gunsmithing and thought I'd give the GP100 an action job and bob the hammer. I like the results and now the GP100 has a 7lbs. double action pull, 100% with Winchester primers. Just bought a S&W 627 and that will be my next project.
