I've owned 3 (worked on lots more) tang safety Rugers- still have 2, sold the .25-06 V (bought new on sale at Penneys-I was looking for a .264 Win Mag- in Fairbanks about 1975 for $165, plus tax.) in a moment of extreme stupidity- it was the best of the lot. Killed over 2 dozen caribou with that one- factory standard, with fiddle-back stock stem to stern. DAAAMN! Did need fire-formed neck sized reloads to shoot MOA. Factory loads clocked about 5 inch groups..... 26 of 27 caribou were bang-flops once I got the hand-loads worked up (with a $19 Lee Loader kit).
The '06 was purchased for $80 @ 1985. Once I bobbed the barrel bulge out, it ended up with a 17" bbl. which clover-leafed 3 rounds at 100, then went to 5" for 5 rnds. Glass-bedding the rcvr and free-floated bbl settled it into about 1.25 " all day long, most any good load, factory or hand... POIs vary.... Too good for the "boat gun" I bought it for (it was ROUGH!- having apparently been stored in wet conditions , or put up wet- after the bbl-bulge incident, whatever that was. I actually bought it figuring the receiver only was salvagable. Required bead-and-blue - which largely camos the fine outside barrel pitting -and stock work-down and refinish.) So I bobbed the fore-end and butt, and slimming down both - it's smooth- no checkering left - making it into a carbine style to fit the wife and to make the proportions look right, and anticipating Ruger by about 10 years!
. With a 1" slip-on pad, "Stub" fits me- and I carry it a lot! The first critter I killed with it was a ram at @ 330 yards, the last two were caribou at @ 356 paced, and 180 yards, ranged. It's taken moose and black bear as well, all at less than 100 yards. No flies on that piece.
The .338 also shoots 1.25 groups or better with most anything- picked handloads gain me just a little, for the most part. It too has been glass bedded and free-floated. And Mag-Na-Ported. (Recoil pad replacement on Rugar 77's goes without saying!) The RIGHT handloads do a little better....
A certain Sierra GK 250 grain hand-load shoots right at 1 inch groups at 200 yards (or 100 yards- I haven't quite figured that one out yet- but who cares????!!!)- but my average moose kill is about 70- never had one over 160 (of 19), to date- so I don't use those loads (but I do carry my last 4 rounds of them- just in case), preferring bullets designed for the shorter ranges. Currently I'm carrying Hornady .250 gr. RN in the thing- MOA groups at 100. These too (as with the Sierras) were some "junk loads" thrown together without any work up just to get rid of them- but they are just too good not to use hunting. Dang - I hate when that happens!! The Sierras print 3 inches higher than the Hornady RN at 100 yards, making them ideal for a 400 or so yard shot, with no Kentucky windage... vvertically, at least. Should I ever need it. I am undecided yet what I'm taking north to Kotzebue when we move this fall- but if it is the .338, I've got some Sierra 250 GK bullets to buy and load up - yes - I DID write that one down. Somewhere.....!
While gunsmithing, and with the '06 and .338 -I found that Ruger tang-models (and the rest as well!) benefitted from glass bedding the receiver and several inches of barrel, free-floating the rest, and doing a trigger job - honing surfaces, and lightening the springs, making screw adjustments etc. The after-market (non-Ruger) triggers are even better.
Factory accuracyon most Rugers without tweaking is nothing much to write home about, but adequate for most hunting purposes. But with a little tweaking.... bedding, free-floating, a trigger job... they clean right up!
Few, including mine, ever lost all their creep on the original trigger, or could safely get much below 4 lbs trigger pull. Both mine (original factory triggers, tweaked) are down to 3.5 - 4.0 lbs pull weight, with only a little creep (I prefer 2.5lbs and no creep - which I have on Mausers with Timney triggers, and my Remington 700's, factory triggers. None of which came that way!
I've killed more game with the Rugers, than the rest combined.....
