m1917 Eddystone Bedding: Muzle Pressure?

[Patrick Chadwick]

noted that the muzzle bearing pressure decreased after each set of shots (went from 2 to less than 1lb). So something is changing the muzzle pressure as the barrel & breech heat during firing.

You have a wood-metal "bimetallic strip". The metal is bearing on the wood, and heats up faster. As long as the bearing pressure remains in the useful range, the effect on grouping will be small. BTW, don't forget to support the rifle on your hand on the sandbag, in the position your hand would be if you were using a sling, if you want to get results with the same POI for freehand shooting.

Thanks. I'll post another range report with the results with higher muzzle bearing pressure. Will also re-check the muzzle weight after the 10 shot groups as done previously

How about shortening the rear stock ferrule a little bit to gain a little purchase at the rear of the action? I have an M1917 that responded well as did other firearms that I own. It was suggested by another user of this site and did wonders for me. It seems that there is not alot of purchase on the sides of the action in a shrunken p-14 m17 stock even when you want to eliminate the left/ right rocking with glass. But the rules will not permit that for CMP. The front action screw and applied tension at the actions screws and how it related to the resulting barrel tension at the nose of the stock was an interesting project for me. And frustrating as well. I cant say how many points all that saves me at the end of standing, but i could definitely see it prone with sling tension just like the other fellow said.

Doco....... Thanks.....when you mention the ferrule are you referring to shortening the rear stock bushing(?)

Just a bit to let grab some better tension at the tang to settle out rear portion of reciver sidewalls and lug flat behind front ring
