I purchased the very first one I found in 1983. Scoped it with a 2x-7x Leupold VXII. Reamed it out to 250 Ackley Improved. Sold it. Tried to buy it back after realizing my mistake, no luck. Purchased 3 Ruger 77R rifles in 250 in later years, two for my 2 sons. Bought a third 77R in 250 and figured I had enough already.
I forgot to mention that other than the two my sons have, I barreled a Ruger 77 Mark II 6mm Rem to 250 Savage Ackley Improved using a Shilen blank. Shoots incredibly accurate, in fact I do not know how accurate because it groups as well as I can hold now. 3/8" at 100, 1 1/2" at 200 with 100 gr Ballistic Tips.
I miss the Ruger 77RL but really prefer a 22" or longer barrel to help with muzzle blast when hunting and not having hearing protection on. The 20" barrel really popped when rechambered to 250 Ackley Imp. I cut my Shilen to 24" thinking later I might shorten it to 22". NOT. If you can't handle a 24" barrel in the woods something else is wrong.
I like the odd chamberings, the 17 Ackley Hornet, 250 Savage improved or standard, and .358 Winchester are my 3 favs after the 22 SHORT of course.
If I could find a 77RL ultralite in any short action chambering, I would rebarrel it to 250 Savage using a 22" with standard contour barrel and just relieve the stock forend for fitting the larger diameter (slightly) new barrel. I still LIKE the ultra lite stock, but would really like it with a standard weight 22" barrel fit.
Don't wait for a factory 250 Savage, have one built. Easy peasy.
