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.


My Ruger 77 shoots respectable groups with various combinations of powder and bullets, but I was curious about Seafire's load recommendation and looked in my oldest Hornady Manual circa 1967 to see what he was talking about.

Suffice to say, I saw group improvement on all bullet weights 120 grain to 175, except 160 grain Nosler Partition.

I would post up targets but, Shrapnel said "targets are for losers". laugh


Now why the heck doesn't Hornady still print that data? In some cases it's about 200 fps faster than in their current book.

"An archer sees how far he can be from a target and still hit it, a bowhunter sees how close he can get before he shoots." It is certainly easy to use that same line of thinking with firearms. -- Unknown
