I'll play.
Remington 700, worked over by me.
26 inch 10T Krieger, chambered by me with Serengeti reamer
Brass: fully prepped LC 67 Match, unturned
H4350
CCI 250
FGMM 215M
Vortex HD LHT 3-15X50
Ti PRO 3
166 HH loaded to the 1st ring, closest to tip
Ran QL and picked the charges to start with. The pressure test loads were ran with 1/8 LEE FCD. I did not like the feel, as you are dependent on pretty close to exact case length to be consistent. Decided to drop the step. For the charge validation I just ran the prepped brass with dry lubricant through a neck sizer, no expander.
Loaded ammo at our club stat house. Have a place to mount the coaxial press.
See the note at 58.5 - swipe marks, I quit at that point and picked 57.5 with intention to do seating depth test. Used different fresh targets. The CCI ignited 2 rounds bunched together. Instead of loading more of the same, I wanted to see how sensitive is that charge with different primers. Primed a couple, loaded them with the same charge and same COL. Seems no POI difference.
Not done yet, still work in progress, just hoping to add the data to GL Taylor's data. In the next few weeks before the opening day I plan to go back to the range at least once a week to shoot cold bore and a quick follow-up. No 5 shot groups as the intented range to harvest deer would be inside 300.
As long as I can hit a 3/4 inch paster with the 2 shots on every outing that's GTG on my book. I can kill deer with it. FYI, point of aim is the center crosshair.
Note: jotted down 67.5 on the target, should have been 57.5.
Interesting to note. On the bottom picture there is another 230 caliber hole from a different rifle. The holes left by the 166 HH do not even come close in appearance to the other hole.
