Well, I took my new stick to the range for the first time today. Basic stats are: Savage single shot target action in RBLP configuration, 28' Broughton 5C barrel, Sharp Shooter Supply Dogtracker stock with an adjustable buttplate installed, Nightforce scope.

Now, I have never owned a 6mmBR before, but from reading here and seeing them in action I decided to build one. It's main purpose in life is mid range F-Class shooting, mainly 600yd, and if the winds are favorable 1,000,have a 6.5 already for 'normal' conditions) I am most grateful for all the info here, and especially the load data. I picked RL-15 under the 107 gr SMK's for my first loads, starting at 29gr, and proceeding in half grain increments to 30. Jumped the bullets 0.015. Ran the Lapua brass through the neck sizer bushing die, and was concerned at the force needed to pull the expander button through the virgin brass necks but figured this was a once per case deal to round them out for initial loading,once all 300 are done and fired I'll be back to the normal no-expander routine), When I measured the runout on the loaded rounds, I was appalled as they had more wobble than anything I personally loaded before, but I kept reminding myself that this was the fireform/chronograph/scope and gun trial stage.
So off to the range this morning. No wind here at the house, so life was good.....until I got to the range and it started to blow,the wind, that is). So I set up everything, leveled the gun in the bags, leveled the scope to the gun, made sure the bore was in the center of the chronograph, etc. and boresighted. First couple of rounds were off to the right, so I moved the scope over 5 MOA and fired another shot, hit paper with it, so I shot 2 more and stopped because I couldn't tell what was happening. A walk down to the hundred yard berm revealed a nice hole that measures 0.335 at it's absolute widest edge to edge
that's the smallest 3 shot group I've ever fired with anything. I am so in love! I kept going til I worked my way through my first 100 rounds, and with the conditions was more interested in the chrony numbers than group,,though 20 shot strings yielded nice quarter sized holes) and found that as my charges got heavier the SD was coming down,the 30gr load gave me an SD of 9). I can't wait to see what will happen with some load tinkering, as well as bullet trials,have Bergers, AMAXs, and Lapuas waiting for the next trip).
