783 Varmint

hoz53, The triggers are fairly easy to tinker with. Everything loads from top & bottom, no side plates. That and a bunch of jesus clips, as in: "jc, where in fecking hell did that mofo POS go?", make it a slight PITA to work on. Usually though, they don't need any improvement. Adjust down to 2.5# or so, clean break, no creep. Once in a while you get one that is creepier than Hillary. That requires disassembly and polishing all the contact surfaces. Polish only, do not change the geometry. They are MIM parts, surface hardened only. The polishing should take out the creep. On one of the 10 I've worked on, I had to replace the sear. I had one that had a nice clean break, but would only adjust down to 3#. To reduce the pull weight further on this one and some others, I had to install a lighter trigger spring. A ball point pen spring works great. In particular, ones that are black and say us government on the side. A ballpoint spring will be a little longer. You can cut off a few coils or just install it compressed slightly. You can get total pull weight down to the 1.5# area. Just remember the center safety arm requires about 8 oz of the total pull weight. Essentially, 1.5# actually takes 1# to break if you treat the trigger as a two stage. Pull center safety arm till you hit the wall of the main blade then break the shot. I have found 2.5# is low enough. YMMV.

Jim, If you can now torque the rear action screw to ~ 35 in-lbs it should work. If not, check out bushings at Lowes. Do a search for 1/4-in bronze machine bushings. In particular, item #215870. Will need some fitting with dremel and grinder. Even with the bushing, you end up with a suspect plastic pos that will fail.

For those of you on the fence about buying one, I say do it. You can make them into what ever you want. I am not a rich man, far cry from it. I also have other places for my money to go. I can't afford the high dollar chit. for example, I have a boat. BOAT = break out another thousand. Luckily don't have a wife. WIFE = wasting income for enjoyment. If you have both, holy crap. Bottom line is if you wait for sales, you can pick up a complete 783 for $269 or so. If it doesn't shoot to your standards, swap barrels. The action will shoot very well indeed with a decent barrel. You can get a Green Mountain prefit barrel for $200, an X-caliber for $280 & other for more $. You can get a Boyds stock starting at $99. So, for under $600 you can build your own custom rifle to your specs. It will be very accurate, therefore interesting. How many people have an XL7L in 257 Weatherby? I have one, hope nobody else does. I have slowly acquired a bunch of actions over the years. Now, if I want a new caliber, its just a matter of ordering a new barrel and if required, dies brass and bullets. Next thing you know you will need a new safe.

I am not a trained gunsmith, just a self taught basement shop gun tinkerer. If I can do it, you can do it. Build your own, you'll like it. Mike

Just read this Mike. Thanks for all the info. I only have 2- 783s and have really only torn apart one of those. Just got it put back together. Its in 6br so i wonder how many people have a 783 in 6br? I like your idea of a 257 Wby in one and i have the reamer so its a possibility:). Id have to buy a magnum model though. When i can get out shooting again ill give these 783s a workout and see how they do.
 
I just wanted to thank you guys who have posted so much information on the 783 rifles. I have paid no attention to these at all and had no idea that so much could be done with these rifles. I wrongly thought that they were just another throw away entry level rifle.

Pics of X7/783 triggers and bolts for comparison. Stand by race fans, I think I got this pic posting chit figured out. :) Edit: Added pic of 257 Weatherby: XL7 action & trigger, XL7 bolt w/783 bolt head, factory laminate XL7L stock, custom 783 prefit barrel. It's a Marlington.
oh and i didnt know GM made any prefits especially for 783- i got a 17" Heavy GM barrel in 30- thought mabie that would be a good one for a 783 in Blackout. thanks

The GM prefits I have were made from GM blanks, throated to my dummy rounds. When I started doing this, I went with economy barrels. As there were no prefit barrels available for the X7, I talked a guy who sold Savage prefit barrels on eBay into doing me one shortened for the X7/783 bolt face. His cheapest blanks are from GM. Retired machinist, he does excellent work, no tax, free shipping. If interested PM me, I'll check to see how busy he is. Current price is $210 for doing a GM CM blank. My GM CM 25-06 will put three 115 Partitions into less than 1.5" @ 200 yards all day. It'll put five 90 SBKs into less than 1" @ 200 yards pretty much every time. I kinda like the cheap POS.:) Mike

Thanks for that info. I have a lathe and been starting to chamber my own barrels. First one i did was a cheap GM strait taper .224 blank to practice on. I had to cut it off and start over once or twice but i got it. Its in 22br on a rem 700 and seems to shoot really well. Ive got several chambering jobs on my stuff to do on R700s soon. Ill have to try a 783 barrel one of these days. Ill think about that. Those GM barrels do seem like a great value. I wonder how long they will last for.
 
...... I wonder how long they will last for.....[/QUOTE said:
That would be the $64 question. I also have a GM SS in 22-250. Probably find out with that one the fastest. Round count is @ 478. Time will tell. Still cleans up easy. I would like to have a lathe and the skills to do my own threading and chambering. It's got to add more self satisfaction to gun projects. Kinda like buying flies or tying your own.
 
ill get out there shooting that 22br all i can this year and see how it holds up. i have another GM barrel in 224. i think i will turn it down and put it on an action in 223. that gun was a 223 varmint R700 --Ive yet to buy a Kreiger- ect high dollar barrel but that day is coming.
