Anyone with a 308 Crusader willing to share their COAL and Ogive for a particular projectile?

Just picked up a Crusader with under 40 rounds fired. Doing my typical look over shakedown, I was measuring COAL and ogive to load up a few fun/fouling rounds and begin working a load when I noticed the chamber seemed shorter than other 308 GAP's I have/had.

The COAL and ogive for 178 Amax I came up with was 2.790" COAL and 2.090 ogive. Didn't have any loose 175 SMK's to try but looking at some M118LR and FGMM I Haden hand, both seem a bit longer giving a bit of jam if similar to the Amax in ogive.

On my other 308's with same 178 Amax I had a FN action build that was long at 2.875", a Remington action build I still have with 2.846" and then my Surgeon action build with 2.840", all significantly longer than the Crusader at 2.790".

Not worried about it, will just work a load as I have in the past, but it has me curious if the Crusader as a model has a chamber more for factory ammo, or maybe just this one. I know my other sticks are not chasing lands or the like--at least wouldn't think so, all have less than 1000 rounds through them. Just one of those quirky questions that will itch my brain.

Thanks for any input.
