Finally got back to 1903a3 load testing and finally a decent load!

[mac1911]

Here's what my M1903A1 NM Type II does with the 164 gr 30 XCB and a 158 gr 311466 using SR4759 and 2400 powders with a Dacron filler. I built the rifle starting with just a DHT action the only part I've not found is a right side safety. I used a new Remington 4 groove barrel. It shoots 10 shots of my 175 gr MK loads into moa all day long.

I dovetailed the Lyman 17A sight into the '03 front sight base, soldered it in place and then trimmed up the sides. I got the correct height from measuring Scharfschuetze's M1903 front sight.........

Cases were LC 67 M72 match and primers were WLRs. Bullets GC'd with Hornady's, were sized .311 and lubed with 2500+.

These targets (NRA 600 high power reduced to 100 yards) were shot with the 30 XCB over 19 and 21 gr of SR4759 with a Dacron filler. I only chronographed 10 shots each with an Oehler M35P. The 19 gr load is a 15 shot group and the 21 gr group is a 20 shot group. On the 21 gr target I dropped for points on that score for a 196-10X.

This is 3 consecutive test groups with 18 gr 2400 with a Dacron filler under a 311466 sized .311, GC'd with Hornady's and lubed with 2500+.

Even with the match Lyman 48 rear sight and the Lyman M17A aperture from my old eyes won't hold much better than that.

Nice... lack of time keeps me from shooting and testing loads. I'm sure this rifle has it. I just don't.
I might remove the scope from my RRA a4 clone and put iron sights on that and then dedicate current a3 to the target sights.

That's a commercial safety for use with a scope..

That group with 13 gr of Red Dot loads looks like mine... great stuff.. especially with the NOE 311332..

Good Shooting guys !!

I know this is not the swap and sell sec, but I came across this part that I believe is from an 03a3, it looks like the safety lever. I have no need for it and will post it for sale. any interest?

fwiw, it is a civilian replacement "low" scope safety for an '03 bolt. I think several companies have made these. I have two 03 sporters w them. Both of mine were made by Buehler. If my effort at attchments worked there is a pic of my vintage 22-250
w one installed.

Today my Smith Corona 03A3 did real well with an NOE 312299, PC, GC sized to .311 over 37 grains of 748 with magnum primer. I have a photo of target but having issues loading it.
