I'd rather shoot a 2 MOA Remington than a 1 MOA Ruger. Of course there is little chance of finding a 1 MOA Ruger.
To each his own, but I have 3 Rugers that all shoot MOA. A Ruger RSI M77 Mark I in .243 Win, a Ruger Mark I M77 in 30-06 and a Ruger Mark I M77 in .280 Rem. Admittedly I use only handloads, so worked up loads for them but all of them shoot well with different weight bullets with slow burning powders like H4350, IMR 4831, H4831, IMR 4350 and standard primers. Someone posted a while back that the early Rugers had Douglas barrels on them. I don't know if mine do, but all of them are very early model M77 Mark I's. The loadind data for them are
.243 Win 42 gr H4350 or IMR 4350 using 100 gr Sierra BT or Speer flat base bullets. All minute of angle at 100 yds=.6"
.30-06 59 gr IMR 4350 or H4350 using 165 gr Nosler Pt or Sierra BT=.8"
30-06 54 gr IMR 4350 using 220 Sierra RN or Nosler PT=.75"
.280 Rem 55 gr IMR 4831 with 145 gr Speer BT, 54 gr of IMR 4831 with 150 gr Sirra BT=.4"
All these for 3 shot groups at 15' above sea level, temp at 45*, no fouling shot, scopes are Leupold VariX II 1x4.
I realize these loads are at or slightly over maximum in the loading manuals and do not recommend them for anyone as a starting load. My particular rifles like near max loads for best accuracy with the bullets I use.
