mausernut,
Thanks for the comment.
Yup Sub MOA. I didn't expect that at all. Using the HXP I got the normal 2-3 inch group.
I took a 10 - 15 minute break to let it cool down. Then, just for the heck of it, loaded three Hornady Match rounds that I had remaining from having sighted in my M1903A1 for an upcoming vintage military rifle match. I fired each round cycled from the mag, didn't even check the impacts with my spotter scope until I had fired all three rounds. When I did look, my first words where "Holy S**T!" That Hornady load with the 168gr A-MAX bullet is awesome.
Now here is the best part.
This rifle is a "bubba gun" that somebody had tried to sporterize. I paid near next to nothing for it, was sort of looking at it as a parts gun for my other 1903s. After cleaning it up, figured I would test fire it to see how it would group. You have seen the results, which I have since repeated.
Here it is in all of its bubba gun, redneck gunsmithing glory.
I'm getting together all of the parts to bring it back into USGI condition.
