Progress on the RSI 7X57

[Thumbcocker]

Tested a few more loads today. Making some progress.

looks like it's holding pretty steady.

 

[Spindrift]

Looks fine to me!

 

[Thumbcocker]

I might be able to tighten things up a bit with brass prep, match primers, and weighing boolits. Biggest problem is a real heavy trigger. Looking into an aftermarket one.

Trigger, give Timney a try.
Might fiddle with seating depth a bit in 0.010 at a time. I usually start at 0.030 into the lands and go in/out from there.
Could tweek powder charges +/- .5grs at a time as well. It never ends.

 

[Thumbcocker]

Unfortunately no Timney triggers for Ruger number 1.

 

[Ian]

Lock time is glacial on a #1 also, a lot can go wrong after the sear breaks. Barrel harmonics and the forearm/wooden mainspring cover can be problematic, too.

How well does it shoot jacketed bullets?

 

[Thumbcocker]

Only shotv20 rounds of S&B 140 grainers through it. They did not shoot as well as these cast loads.

Canjar use to (back when they existed) make a No.1 set trigger. Depending on the No.1's vintage it could be a barrel issue. Before Ruger began making their own barrels the purchased barrels had a bit of a spotty reputation. Also as mentioned the barrel hanger forend and the long hammer arc combined with the two-piece firing pin don't help matters.

 

[Michael]

Oops, thought it was a 77. Never mind.

Those targets look completely adequate to me. Especially for a carbine with a two piece stock. It's a little hunting rifle.
