Got a nice day today so I did some more work on my recoil pendulum. I did some testing between my handloads and w-w white box loads and got a consistent repeatable difference between the loads. I need to lighten the swing some more and put some leather on the rifle cradles. I also want to build a way to pull the trigger without affecting the recoil. Then I will recalibrate and tinker with the buffer stuff to see if my xtra buffer works.

I hear that bro, congrats! … I have about five more years to go in the ‘Salt-Mine’ and at this time and juncture, I can’t even grasp the concept of the term ‘Retirement’

Glad to see some people really take things seriously. Nice set-up you've made there.

I did some shooting yesterday and put 50 rds through my recoil pendulum. I swapped out buffer parts and shot my reloads and white box. The w-w recoiled more than my handloads as expected. I used the same 8 oz heavy buffer for everything. Using the Tubbs 223 spring and my SB ( short buffer) I found the rifle recoiled less than when using the Tubbs and the delron spacer. Using a cut carbine spring and the heavy buffer I was surprised to not see higher numbers than I did. However, I was curious about this and shot the rifle offhand and found a substantial felt difference between the carbine spring and Tubbs spring. I could feel the bcg slamming forward. I will test again after I get regular carbine and rifle buffer springs. My SB unit is working and does 2 things, it protects the lower from being hit by the bcg and it smoothes out the movement of the bcg. My pendulum is just not sensitive enough so I need to lighten it some more or counter balance it with a weight. I also might replace the sheet rock screws with the smaller head finish screws and go with 1/2 inch increments instead of 1 inch. While I do show a consistent difference between loads, changing parts does not show as much difference as I would want. There is also the other half of the felt recoil, and that is the return to battery motion. While it is technically not recoil it does affect repeat rounds on target. More testing needed.
