Got up early this morning and hit the range to do some testing on a new Barrel Tim Claunch chambered for me.
Since I mentioned Tim he had talked me into giving RL-15 another try so that's what I did. I set out with 20 rounds loaded at +.011 into the lands using 32.0 grains of RL-22 with a CCI 400 primer with a 105 Berger VLD
These 20 rounds were to find my optimum seating depth.
The morning started off hazy and not being able to see my bullet holes on the white cardboard I shot my first 3 shots and drove down range to see where impact was. I was low 3 clicks and right 2 clicks so I made my adjustments and based on the first three shots I began the seating depth by seating loaded rounds in .003 on each session of 3 shots further away from the lands.
By the time I had shot up my test loads I drove down did an observation of the target and seating depths and there were 2 promising depths, one was .001 into the lands and the other .005 off the lands. So I chose the .005 off and went back to the firing line and began seating all my other test loads at that seating depth.
The rifle got a good cleaning and then a few fouler and sighter shots and I began testing a higher powder charge of 32.5 grains and also I had two other sets of loads of 32.0 and 32.5 grains of RL-15 with the CCI 450 primers.
By the time I had gotten a few rounds fired to foul the barrel and get a new zero I noticed the mirage was just miserable so I cranked the 15-55 NF back to 45x and looked and I was still unable to make out the 1" orange aiming circle. So I backed it on off until the picture cleared up and I began the test.
Here's what the morning looked like at 500 yards setup at 6:30 am it was a bit hazy then.
Now here's my target testing after the initial seating depth test. Top left is the 32.5 grain charge with the CCI 400, bottom two from left to right is 32.0 and 32.5 with the CCI450
Here's the 32.5 CCI 400 group size with bullet dia subtracted.
And here's the 32.5 group size using the CCI450
Did I mention the mirage was miserable during this test? If not I'll say it. It was so bad I was afraid to even go look to see what mess I had down range.
Also prior to this test the barrel only had 13 rounds fired thru it.
Thanks for reading and comments welcomed...... Oh and I hate the cold.......
