Removed the 6.5CM barreled action from the LRT and put it back in the factory stock, then fit the 7BR barreled action to the LRT. Loaded test rounds about 2 weeks ago and was just waiting for a good weather window which finally happened Friday.
Pulled my bench out and set up. Re-zeroed the 6.5CM then set up chronograph prior to shooting 7BR. Shilen recommends shoot 1 & clean for 5 rounds, which I did while getting scope dialed in. Fired up the chrono then proceeded to shoot 4ea 3-shot groups. Rounds 6, 7 & 8 produced the group circled in green, I forgot to adjust elevation before the first shot of the next group circled in red...
I use corrugated plastic for backers and they were quite wet from morning fog, so waited to measure after they dried, the three holes on left measured .712"...
The final group at 26.5gr openend up a bit, but still respectable with only 17 total rounds shot...
Disregard markings on targets, I save unused sighter targets for home practice. When I ran my borescope down the barrel afterward I found no lead fouling at all. Hats off to Shilen for a superb finish!
This is very promising and anxious to start a ladder test from 24.5 - 26gr. The 25gr load had avg vel 2048fps, ES 4.0, SD 2.0. :-)
