More range results today. My rifle is a 22" Winchester Model 70 EW rebored from .308 Win by JES. 1:12" twist and 3 grooves. All speeds were measured with a Magnetospeed chrono.
225gr Sierra SBT-GK with 49gr TAC produced 2442fps
200gr Barnes TSX with 52gr TAC produced 2580fps
180gr Barnes TTSX with 54gr TAC produced 2681fps
250gr Hornady RN with 48gr TAC produced 2290fps
With the exception of the Barnes TTSX load listed above all the loads produced sub-sub moa accuracy at 50yds. The most accurate load for the 180gr TTSX was 53.5gr of TAC which produced 2669fps.
I loaded 10 of each load above. 5 were tested for accuracy and 5 were tested for speed. I don't perform both tasks at the same time as there is usually a POI change with the chrono attached to the barrel.

I also shot ladder loads with my 35 Rem chambered Rem Model 7 today. Interesting note: I achieved more than satisfactory accuracy and 2175fps using LVR powder and the Speer 220gr HCFN.
Thanks, Dinny
