Set Trigger Adjusting

[TomP]

I bought a Lyman Great Plains flintlock .50 rifle late last year and plan to hunt with it this deer season.  Right out of the box the set trigger pull is pretty heavy.

I removed the trigger assembly and found 3 different things that can be adjusted.  One is the rear trigger spring screw that holds the spring to the trigger plate.  The tighter you turn it the heavier the spring force.  The second adjustment is a set screw that determines when the rear trigger begins to push against the spring when you cock the rear trigger.  The third adjustment is a set screw that determines how deeply the sear of the front trigger engages the rear trigger when its cocked.

Can someone share some advice or experience on how to adjust everything to get a safe and light trigger pull?

BTW, the sear surfaces seem to be smooth and without burrs.

All I can say is to play with it.  

I was able to set the second-stage trigger on my GPR 50 cal. to a break point that my brother calls a hair trigger.  After pulling the rear trigger for the take-up, all I have to do is breath hard on the front trigger for it to go off.  The result is a BP rifle with more accuracy than I need - I also went "non-traditional" and installed the Lyman peep sight on it, extending my sight plane by about a foot.  That didn't hurt the accuracy either.  Believe it or not though, the intended use is for deer and javelina, not target work.

Experiment with the set up before you reinstall it in the stock.  I don't think you will break it, and I am sure you will find a sweet spot in it for yourself.  By the way, I'm working on a 54 cal. GPR right now and will go through a similar process once I get the stockwork completed on it.

Good luck, and let us know how it goes.
