Bedded the rifle last Wednesday. Mounted the Nikon Monarch 2.5-10x42 mildot and brought some Federal Fusion 165's to my "range" and broke in the barrel.
High reading on the chrono was 2818 and low was 2660 (I think). ES was 158 and Sd was something around 65 during break in.
Break in was fire one and clean for the first 5 shots. The first shot took 3 patches with KG12 Big Bore copper solvent followed by a patch or two of Hoppes and two dry patches--swabbing from 10-20 times each patch. This takes a long time, but I was trying to be patient and thorough.
First shot showed that looking through the bore and through the scope at a target in my back yard about 75 yards away had me pretty close to being on target at 50yards moved back to 100yards for shots 5-10:
The second shot took one swab from KG12 and the next swat showed almost no copper...Hoppes took a swab and two clean patches...
The rest were about the same...one to two swabs of KG12 max and one Hoppes and one dry...
After 5 shots the bore was as smooth as butter...that is to say it started "smooth" and got smoother...My old Tikka's bore wasn't nearly as smooth until after I used Tubbs on it...and maybe it's the broughton 5C rifling making the difference but this is tube is a pleasure to clean...
Didn't get to the OCW test yet. Only ten rounds down the tube.
Interesting thing was with my cheek on the cheek piece, the whole thing would sit and hum for a few seconds after each shot...if I had to get the note I would say it was F...but I'm not really a musician--but I'll bring my guitar tuner next time and see what it is...
Saturday or Sunday I should get some time for the OCW test at 100 yrds.
