had two of those Rugers...
both shot like crap...
until I tried ONE load and it turned out to be the sweet spot for those Rugers....
with any bullet weight from 139 grains to 175...
40 grains of IMr 3031... got it out of an older Hornady Manual...
have passed it on to others on the Net, that have had the same rifle with the same problems.... and it solved most of their accuracy issues also....
I shoot everything from 100 grainers to 175 grainers in mine...most common deer load is 140 grain ballistic tips...
got a ton of them for cheap years ago at Nosler's shooters pro shop...
If I had to go generic.... Hornady 139 SP, or 154 SP....or Remington 140 gr Corelokt.
