This morning was a nice morning to shoot so I headed down to my range by the river.Got my Crony set up and started running some 3 shot groups over it using Hornady 123 gr.ELD Match bullets and some CFE223 powder and Rem 7.5 primers.I did all my shooting at 200 yds.The temperature was sitting right at 32 degrees.My Crony does not like the cold so I would have to warm it up regularly in my truck when I walked down to my target to check it out.My COL was set at 2.310" for my Howa 20"HB.
Earlier I started some load development with some 123SST's and CFE but ran low on bullets that I needed to hunt with so I continued with the 123ELD's starting at 31grs. and increasing the charge .3 grs. at a time.Average velocity increase was 26fps.At 32.2 grs I reached average 2607 fps with 22fps extreme spread and a 1.25" group.That was the best I could get.I took the charge up to 33.1 grs.,quite compressed and received 2679 fps. with no issues.
Tommorow I will play around the 32.2 gr. area with slight charge increase and seating depths to double check my shooting.
