RMR 69g and Shooters World Match Rifle for HP competition out to 300 yards.

Works very well with 25g seated at 2.260. Workup was done using the OCW method.

The link below is to an image from a match this weekend Feb 12, 2022 shows the result. Wide 10 shots low were first shots, after adjusting to the waterline a small group formed on the left side of the X ring at 9 o’clock. A 1/4 click right moved the group closer to the X ring. I should have clicked one more right and earlier.

The one shot at 8 was shot 19 and likely me raising my head. Match was a 500 agg 100 yard and this was the 20 shot slow prone using the MR31 target in the prone/sling position. For those not relating, the 10 ring is 1.75 inches and the X ring is 0.75 inches. If you shoot well from a bench the results should be better.

Note this load works well for me in a CLE chamber, please start out 10% low and work up in your rifle looking for pressure signs. It is noteworthy the load is below the Shooters World Match Rifle recommendation for 69g bullets, that puts it within manufacturers range. SWMR says 25.3g works for 69g bullets. Velocity measured 2889 in a Rock Creek 1-7.5 20″ service rifle barrel and 2984 in a White Oak 1-8 20 inch Service Rifle barrel. Measuring was done using a MagnetoSpeed.
