I just finished my first build over the weekend. Took a long weekend and used a vacation day. Of course it's just my luck that the site has been down, and I ran into a few problems, all solved (or fixed) except one. Boy, that tutorial would have been nice a few times.

My trigger pull (KMT with machining by Brian), is atrocious. Probably 20 lbs. I also noticed that when pulling the trigger, the back of the bolt dips down .050" or so.

Is this normal? Is everything just tight?

Check your back plate!...It might be that your back plate may be dropping causing a clearance issue with your trigger...Try this!....Cycle the gun to set the trigger / Pull the back plate, all the way up as hard as you can with one hand and pull the trigger...If that helps...remove some metal from the trigger slot....In my case on my ORF, it took two hands to pull the trigger!...I added a piece of rubber sweeper belt in the bottom slot of the back plate groove to lift it and take away the slop..It runs like a champ now...HTH

Make sure that your sear is sliding smooth in the slot,, smooth out any metal to metal contact,, also make sure your headspace is good,, if the bolt isn't locked up, the sear is not in the optimum position for engagement of the trigger. I had some TTI's (tight trigger issues) on my last build,, ran a few rounds thru it and it smoothed out,,, LUBRICATION. I sprayed the internals down with "Blaster" and cycled the heck out of it.

Well, I checked for clearances, everything looks good. I tried another bolt from a build waiting in the wings. That was a little easier pull. Took my bolt from VOW built 1919 that has 5k rounds thru it. The trigger pull was light and crisp, although the bolt still moved when the trigger was pulled. Lubed everything up and I'm going to take it out over the weekend for a trial run.

One semi stupid question. The bevel on the locking block does face towrds the front of the gun, correct?

Breech cam lock ramps toward chamber,, this allows the breech block to drop out of battery on recoiling, allowing the bolt to retract. here is a parts blow up,, you have to look close for the cam,,, #19 http://browningmgs.com/Diagrams/Parts Lists/B-14wList.jpg

The bolt moves on every gun..It has to be a sear issue...KMP triggers are vary crisp!...Vary short throw!....Do you have the plunger stile return spring?
