Since my 308 heavy barrel is running out of rifling after many years of shooting, I decided to get something to replace it while it goes off to the smith for an action true and new barrel. The accuracy is still there, but I have to set the overall length to 2.9 in order to get good groups and that won't fit in the magazine box.
I sort of had my heart set on another 308, but the LGS had a Remington Long Range rifle in 30-06 for a good price so I bought it along with 100 winchester factory loads so I could warm it up and save the brass to reload. I put a Vortex 6x24 HS scope with some Leupold rings and bases I had here-they are going to be replaced with EGW parts as soon as they arrive, but I wasn't going to wait around to see what the rifle was like!
I really like the factory stock, a Bell & Carlson M40, aluminum bedding block with a raised comb which fits me well. The top front of the comb is slightly notched in order to clear the bolt for disassembly. Once I got it sighted in, I tried for some groups and try as I might, could not get it much less than 1 MOA. I suppose some of that is due to it being a new rifle and some of it is due to the infamous Mark X trigger it came with.
I guess that X trigger is a hit or miss. Some people I have spoken to say they like it and some cannot stand it. I tried dialing the pull weight down with the adjustable screw, but could not get it down past 4.1 pounds average. Actually, 4.1 was the low end according to my pull gauge. It ranged up to 5.3 at the same setting so I decided to buy a Timney on some folks recommendation and I have to say I am happy that I took their advice.
I watched a few videos some people had made about swapping the trigger, including a fella that hit his hand with a hammer trying to drive out one of the pins! And some folks telling me that sometimes minor mods to the stock are necessary-had my files out and was prepared for it, but it wasn't required.
The Timney 510 I purchased went in without a hitch. Drove the front pin left to right until it cleared the trigger housing, and the back pin right to left until it would turn loose of the housing but kept the bolt stop lever and spring captive. This trigger is so much smoother than the factory model that there is not much of a comparison between the two. I left it at the factory setting and my trigger pull gauge averaged just a bit under 3 pounds pull weight, clean and consistent. The trigger itself is a lot wider than the factory unit and is grooved where the Mark X is smooth. I like that.
I know its no Jewell trigger, but it will certainly do for me.
I took the now fired brass and loaded some H4831 behind some Nosler 175 grain Competition bullets sized to 3.330 OAL. According to my gauge, I hit the rifling at 3.341 using the same bullet and hope to get it back to the range later this week to see what it likes. 10 rounds each from 58 to 62 grains of powder, or book min to max load.
