That is a fantastic rifle.

With all the money spent on "custom" receivers I dont know why the '03 receiver isnt chosen more often for the basis of a custom build.

. . . . . . I dont know why the '03 receiver isnt chosen more often for the basis of a custom build.

About the only detriment I can think of, for not using an ‘03 receiver/action, is the s-l-o-w “lock time”!

Looks promising. Just have to tweak my zero a little bit. Ill be putting a Unertl on it to try but am considering a Leupold 3-9X with mil dot for the final sight device.

That was my first trip to the range after receiving it and in order to ensure I will be on paper at 100 I started at 25 yards.

Ammo was some hunting type 150 grain I picked up just to get on paper.

What looks promising is the continuity of the 1300 impact when I was shooting at the 1 inch circles.

Now that I know Ill be on paper Ill work my sight settings at 100 yards and try to tighten things up.

I intend to see what it will really do with some of the Creedmoor 167 grain Lapua Scenars in Lapua brass I bought from the CMP.

It will likely be 100 or so rounds before the barrel really shines also. Optics should shore up where my eyes fail.

Ill try to shoot this weekend and will provide an update.

Made it to 100 yards this past weekend...

Shot some Fed Fusion hunter grade 150 grain lead tip to confirm sight settings....

Moved to the Creedmoor 167 Scenar in Lapua cases, match ammo...

I was impressed that 5 shots went into a tight knot and that when I pull shots they actually hit my point of aim. For iron sights I think it does well.

Next Ill be moving to a scope.

I found the Match rounds to be a bit hard to extract though. Im having the builder recheck the chamber it might be a bit too tight.

reloads?

[pmclaine]

reloads?

CMP purchased Creedmoor 167 Lapua scenars in new Lapua brass. Disregard that the chart below claims them to be reloads, they are factory new match rounds. Very good ones I might add.

My reloads wont even chamber.





Builder painted up one of my reloads with Dykem and found the area at C to show slight bulging.

The reloads are KA brass fired some 4 times in 1903s or a Garand.

I load on a Dillon and I wonder if the progressive size die, kind of beveled to assist the progressive reloading, doesnt squeeze that area of the brass enough for my tight match chamber.
