@19dsniper , Welcome back, and glad you had a good trip!
OK. Let's start over.
I'm a firm believer in crimping, but I have a couple of wildcats that Lee doesn't make FCDs for - so I've got 2 calibers that I shoot uncrimped. Both are capable of 0.3-.05 groups uncrimped with .002 neck interference (tension). Both were taken to pressure (ejector mark), then dropped back 1 grain.
Maybe your rifle is an anomaly? We already talked about fore end pressure for a "noodle" barreled rifle. You may want to check this - or, you may just need to change bullet weights. As stated previously, I've had 2 barrels that absolutely would not shoot a particular weight Hammer - yet they shot another weight very well? Goofy I know, but it has happened.
Jump does not seem to materially bother Hammers. Keep increasing your jump if the bullet doesn't want to shoot. I know this reduces powder capacity - and the CM is stingy on space - but jumps of up to .200+ are not out of reason (or farther!)
Don't waste bullets or components.
If your rifle doesn't like the 125HHTs, go to another bullet. If not an HHT, the Hunters work very well and are still my personal favorite.
Keep us posted. This kind of stuff is intriguing-and a head scratcher for sure!
