First Trip Update
Well, I got a sticky magazine, and will try to squeeze a replacement out of Ruger. Not unanticipated as magazines for this design are, apparently, the hardest part.
Mine is prone to vertical stringing, and so was my 77/44. Just too much forend pressure on the synthetic stock. The upside, although vertical is about 4" at 50yds, horizontal is closer to an inch. The 77/44 was worse, and full power loads show the worst results. After carefully relieving forend pressure with a Dremel, the 77/44 now turns in 5 shots on a 3" dot @ 100yds, group after group, I am betting the final results with the 77/357 will be better. The trigger is brutal, and I had to look once in a while to see if the safety was on, no kidding. The 77/44 was just as bad, and after I swapped the trigger spring, and honed the contact surfaces it's very good. All of the Ruger M77 triggers are very easy to work with, and simple as dirt. One thing for sure, no court in the US would believe it went off accidently
William: The COAL is limited to problem free feeding, and loads can be longer than will feed properly. After looking at your post, I loaded 1.580"/1.590"/1.600"/1.610", with 158gr Sierra FP's and 180gr Penn TC Cast. The Sierra's with a wider meplat, stopped feeding smoothly at 1.59", the Penn's, same. The reason, looking closely at the feed cycle, is the cartridge takes a slight angle to the right while feeding. To much OAL and it catches the side of the chamber before it clears the mag, and binds. My 160gr SWC cast bullets fed smoothly at 1.580, 110gr Hornady HP's were fine at 1.58".
Cheezywan: Shooting @ 50yds with the stock open sights, and a six o'clock hold, (bench and bags), the 180gr TC Penn cast and 160gr Carrol SWC cast worked just fine. The Carrol's are loaded moderate with 6.0gr of W231, and accuracy with those at 50yds was MOQB

(minute of quart bottle), the Penn cast were the best I tried for accuracy with 9.0gr of Blue Dot, and were in the 3in range @ 50yds. Again, 60 year old eyes and open sights are not my strong point.
M141A, I'd like to post pics, but I'm not much for camera's, even digitals, and would make you run the other way. Maybe one of my daughters will be kind to me.
All in all, I'm not a bit disappointed with the rifle. I'll get a couple more magazines, that won't stick, and I have a peep and Firesight on the way from Midway. Recoil, no surprise, wouldn't scare even the greenest newbie, and general handling, I rate, a beautiful thing.
