There are occasions when blocks of serial numbers have been manufactured out of sequence, sometimes years later. Ruger does not necessarily produce firearms in serial number order.


It can be used to determine the approximate year your Ruger firearm was It is not necessarily the very first serial number shipped, but This number should be used as a point of reference The above chart shows the approximate first serial number shipped for I've felt several tuned M77 MK II triggers, and while they were a certain improvement over the factory trigger, I still didn't feel they were as nice as a professionally installed Timney.(including Frontier Models) Caliber: 204 Ruger, 22-250 Rem, 22PPC, 222, 223, 220 Swift, 6mm Rem, 6mm PPC, 65x55mm, 243, 250/3000, 257, 25-06 Rem, 260 Rem, 264 Win, 270 Win, 270 WSM, 280, 284 Win, 7x57, 7圆4 Brenneke, 7mm Rem, 7mm RSU, 7mm WSM, 7mm/08, 762x39, 30-06 Sprg, 300 Win Mag, 300 JRW, 300 RSU, 300 WSM, 308 Win, 338 Win, 35 Whelan, 358 Win Mag, 350 Rem Mag Not bad for a gun I put together solely as a "hunting" rifle. I have found that when you do that, most "1/2 inch rifles when I do my part" suddenly turn into a rifle that's going to average 1" to 1.25" (or larger). I am just not much into showing a couple of targets of the best groups because I would rather talk an average. There have been good number of "cloverleafs" from this rifle. Keep in mind this is not throwing out ANY group, this is recording all of them. That is also a combination of 100, 200, and 300 yard groupings.

I've recorded 18 groups with the CoreLoct load and it's averaging 0.637 MOA. Strangely enough it shoots the bulk Remington Corelocts with a max charge of RL22 more accurately. My average accuracy for 12 3 shot groups of 140g Partition loads is 0.807 MOA and that is a combination of 100, 200, and 300y groupings.
