I am well versed in form & technique, so I don't think it's that.
My 3006 bolt kicks, but this 300 seems to kick even more than that.
I don't expect overall energy in the bcg to change at all unless I use adj gas block. I think I am just feeling an impact pulse due to light buffer and/or spring. I'll work through tuning it.
You have to look at it this way... The bullet is out of the barrel before the bolt moves rearward more than a very small fraction of an inch. Gas pressure isn't pushing the bolt and buffer back momentum is. How far does the bolt move rearward before the gas tube is disengaged from the key and the pressure is reduced to zero?? Not far.
That momentum in the BCG and buffer has to be balanced by momentum in the opposite direction, transferred through the bolt face to the rest of the gun, which must reduce the instantaneous rearward velocity of the receiver and stock. The rearward BCG/buffer impulse is then re-imparted over the time that the action spring compresses. Recoil remains the same but it should feel different.
Very strange. I've only fired one which was mine. 9" barrel with 0.102" gas port, basic carbine spring, H3 buffer. 125 and 144 supers. For me and a couple of buddies, we all felt it actually shot softer than several of our 5.56s (carbines / pistols) with basic ammo. The guy I sold it to weeks ago felt the same. He came over and fired a few and was near giddy with how soft it was. I just figured that's how they are; evidently not all. Hope you get it squared away.
Well, my 1st initial issue on this 300blk was a misaligned gas block. It was cycling light and 1 in 4 would not strip a new round. Bore scope w/ 45 mirror showed me the gas block was not aligned. Re-aligned gas block and it began to kick hard. The M27 barrel has a huge 120 gas port.
If your block is misaligned a smidge then perhaps that's the reason why your recoil appears light?
That sure sounds like it is over-gassed to me. Get one of these? https://blackrivertactical.com/WP/Ad...Drive-c6464009
