The load at 75 gr would not have been out of line except for one shot that chrony'd 2605 fps.

Conclusion: got a ways to go with RL17 to get anywhere close to where max would be. Gonna keep going up.

Observation: this 3 groove Pac-Nor was the easiest break-in for me yet and I have Hart, Brux and Douglas barrels. Soak the first patch in Barnes CR-10 and it had carbon only on it, bronze brush 3 times, next patch a little dirty but the 3rd patch was clean. Stopped the clean after every shot on the 3rd shot, stopped the clean every 3 shots after the next 3 and finished the session with no further cleaning.

Observation: 375's are a handful! However it was a cumulative long lasting push and was greatly reduced by my Knoxx stock. About like my 338 win mag was before I rebarreled it to a 338RUM.

It did put out a couple of good groups and shows a lot of promise
