M47C sportster recovery to T status?

[jmoore]

Jmoore (and others) - who added the mark and what was its significance? (interested in theory through to fact - whatever is out there).

I'm not ready to post a theory, yet. Need more info, but the mere fact that it gets noted on the interwebs can mean folk start adding it, thus possibly making further study more difficult.

That's true, & unlike a D6E stamp it would be pretty easy to do....

I received a NOS front trigger guard front screw spacer and set to work following Peters guidelines to set the spacer length. I think the bedding is ”good, but not great” – I will continue to study and plan a review in a few months –The ultimate proof is in the pudding as they say…

Having reviewed my notes on the scope adjustments from last time out, I added two additional 0.003” shims at the front mount (total of 4 rung together for 0.012”). I could then return the scopes windage to its zero position. The “cheap repro” sight bracket has come on and off 3 or 4 times since the last shooting data was taken and is holding a zero setting well.

A week or so back I finally got to shoot with the newly completed forestock using my current favorite S&B 150g FMJ – I also removed the rubber bumper pad from the butt plate that I had on trial. The first 3 shots at 50 yards formed a “touching” group on the centerline 3.5” above point of aim – Brilliant! Shims are working!

I then shot a few more at a 100 yds making small scope adjustments – mainly for depression and continued to shake the new build into order

I finished with 3 groups of 5 at 100 yard on scoring targets – the first group producing 1.58” MOA scoring 41pts slightly low and left with a fixed dead center POA The second group repeated this but slightly high (getting used to the scope adjustments.). The third group producing all “10 rings” with 3 X’s , 1.32 MOA with a lower POA after the first 2 shots – my best yet with this rifle!

So with the shims the scope settings are now 7.75” Depression and 1” Right for the 100 yard zero with the S&B (collimation via shimming successful). The new front end and bedding have reduced the “precision cloud” of the rifle by about 1 MOA….with barely 40 shots fired on the new assembly I will plan a few more sittings before studying trends and any revisions - including grinding the sight bracket to eliminate shims. One of the sittings may include a new opportunity to stretch our legs to 600 yards and also participation in CMP events.

I continue to save for a nice No32 Mk3, however I will have to think long and hard about letting the Bausch and Lomb Elite 2000 go….still have a while to wait to have that problem! The next post on this rifle may be while…

Many thanks to the various gurus and fellow enthusiast that have helped on this journey!

This rifle caused me take a long journey of discovery and effort! To fund the original No32 scope as briefed, I ended up buying and selling bits and pieces to afford the investment. The years of reading here also payed off. I did pick up an original scope in an original square cornered tin a couple of years back. The brackets did not seem to come up individually though - except for the excellent production items by Dr P. The bracket was the last piece to the puzzle this spring. I found that from a couple of brackets brought for the rifles on hand, one of them mated up within 3MOA to this rifle (using a zeroed good quality commercial "slave" scope) - top right group in the target photos (other rifles and bracket options for the other groups). The No32Mk3 also zeroed in the vee-block nicely per Peter L's directions and they are now together at last! Now its time to shoot and fine adjust! Original Boyd sling and 1940's scope cover also featured. Also Kershaw binoculars and case found their way home with me recently because CES..

Took a long time but now it's worth it...done at last. Well done.

[Roger Payne]

Well done. Another one 'rescued'!

Well BAR I have to say that this timeline may have been on longer side but this rifle has stuck by me while I changed jobs 4 times, started and finished a divorce and moved house twice. So its my longest standing relationship! LOL
