Hey guys. I've got a Remington XP-100 with a trigger that's giving me fits. It's chambered in 260 Remington and is one of my main deer hunting handguns. To complicate things, the modern gun deer season in AR where I hunt opens up in only 4 days. I believe the issue is with the trigger linkage rubbing on the stock, but I'm seeking your advice.

I bought the gun used about 10 years ago. 8 years ago I put it in a new McMillan stock I got using the old Specialty Pistols website group purchase. The metal bedding block for the rear action screw was not drilled and tapped at the factory. The gun shot 1-1 1/2" groups at 100 yards and it killed a number of deer so I left it alone. Eventually it annoyed me how the barrel wasn't real snug in the stock. During the off season, I asked a local gunsmith to drill and tap the rear bedding block, although I asked him to drill it in from the bottom of the stock up into the action like had been done on a used XP bought on the SP site. When I picked it up a few weeks ago, I noticed the the rear action screw went into bedding block from the top, the usual approach. He said there'd not been enough surface in the action to attach the rear action screw from the bottom like I expected. Although the barrel and action were now tight and it shot like usual, the trigger seemed worse that I remembered, dropping at 7-8 1/2#. With the action out of the stock, the trigger broke at 2#. I left the adjustment screw unaltered. I played with different amounts of torque on the action screws and found the weight needed to drop the hammer went up as I increased torque on the screws. I put some lipstick on the bottom of the trigger linkage. There was lipstick on the front of the stock, where the front action screw attaches, but not at the rear action screw. Unfortunately, I also saw 5 cracks in the stock at the front action screw.

I e-mailed McMillan last night and they called me this AM. She said as long as accuracy was ok, I could use the gun for deer season and send it to them after the season is over. I'd pay shipping, but they have a lifetime warranty. I didn't realize it, but there's a metal bedding block in the front action screw area that's covered by the synthetic stock. I've played with different amounts of torques on the front and rear action screws. With both screws backed off 1/4 turn from snug, the trigger drops at 4 1/2-5#. I'm going to leave it as is and shoot it Saturday PM. I'm hunting with an XP in 284 in the AM.

I think the trigger linkage is rubbing on the stock, increasing the trigger pull. My questions: What would reduce the trigger pull?
Polish the bottom surface of the trigger linkage.
Polish the areas of the stock I think are rubbing on the trigger linkage.
Use shorter or longer front/rear action screws.

I'm open to whatever suggestions you might have.

I wouldn't take any material off the linkage. Id take it off the stock. All of the mcmillan xp stocks I've bedded didnt have anything near a block under the the front action screw. Its more like a pillar, but doesnt come all the way up to touch the action because of the trigger linkage.

I like your description a lot better than mine. 👍 At the front trigger pillar, there's about 0.2" of stock between the stock and the top of the pillar. My first thought was to remove material from the stock, but after finding the cracks, I wondered if removing material from the stock would cancel the warranty. 🤷‍♀️What would you use to remove the material? Would you just remove enough material to be happy w/ the trigger pull? Thx for your suggestions.
 
Those cracks in the bedding block are weird. I see marks in the hole that looks like the screw is riding hard on the left side and where those cracks originate. I wouldn't touch that stock until McMillan gets it back.
 
I'm guessing that the cracks are due to the stock not being bedded and the action sliding back and forth and the screw hitting the sides of the front block.

Or it's just from the front screw being tightened too much and pulling the pillar up.

You should be able to coat the trigger linkage with something. Sharpie or whatever. Then you can see where it rubs.

Sometimes the sear housing in back rubs and caused problems.

It's probably just a small amount somewhere that needs removed from the stock.

I have a milling machine so that's what Id use. I bet it doesnt take much to free up the trigger. No idea what mcmillan says about the warranty. Careful use of a dremel would get you fixed up.
 
Hey guys, Thx for all the good suggestions. I'll shoot the gun tomorrow w/ the action screws set for a trigger pull of 41/2-5#. If it's reasonably accurae, I'll leave it as is until deer season's over. If not, I'll gradualy tighten up the screws until the accuracy is acceptable. When I return the stock to McMillan, I'll ask them how much of the stock I can remove w/o voiding the warranty. I have a Lansky knife sharpener and have been sharpening some knives. I noticed the Lansky stones look like they might could be used on the stock. I'll ask McMillan whether bedding the stock would help w/ the front action screw hitting the stock and causing the cracks. I've bedded a Winchester Model 70 in the past and it turned out good. One of my XP's I bought on the old SP website has the action bedded and is really accurate. If I decide to bed the 260, I'll do it like the other XP. That should make for a nice winter project. Is anyone aware of a specific video or instructions for bedding the XP?
 
Eons & eons ago I had a XP-100 and had similar problems. I gave up on the bolt action hand gun approach. I made the XP-100 into a nice compact shorty 20 inch barrel single shot .223 rifle and used a Rem 700 trigger. OK to make handgun into rifle but real bad to make rifle into hand gun (shorty barrel & other).

It's no different to bed an xp than a rifle. Just more to trim up after.
