The only thing that separates the two is the 5.56 is hotter and usually has more lead cut into the chamber. SAC has you specify if you want a regular for light weight projectiles or a long range chamber for heavier bullets like 70-90 gr
Do you have the desert tech yet? I have a SRS A-1, I’m gonna get a barrel chambered in 37xc. The XC allows me to shoot a 375 caliber without jumping up to the HTI model. The 37xc is impressive, launching 350/360 ish projectiles around 3100-3200fps.
Dan, I tried to PM you but it wouldn’t let me. Forgive the ignorance I have about this as I’m new to this part of the sport.
Let’s say I buy a a barrel to chamber up for the 37xc I’m planning for my desert tech. I was thinking of getting one from ES tactical. I believe they use blanks from K&P...
Dan, thanks for taking the time to explain this concept to me. I still have a lot to learn obviously. I’m gonna be jumping into this world this year and I trying to research as much as possible in order to hit the ground running
I was told this from a builder today. I’m starting to research things for a future .375 barrel (37XC for my Desert Tech). It’s going to be for long range fun and competition, not hunting. I understand it’s something you kinda have to decide ahead of time because of the big differences in twist...
Don’t forget, all the prices you see are in CDN money. Is about $213 all in with shipping.

Davidson VLD long bullet comparators that clamp to your caliber. I have two 7mm and two for 30 cal. Having two is necessary for comparing bullet bearing surfaces. They are in like new condition. I’ve barely used them.
There expensive new, I think around $30 each.
I’ll sell all 4, for $60 shipped
