I had two of the ruger77
The 40g speer spire point was very, very accurate. What is unique about this bullet is that you can seat the bullet to touch the lands and still use the magazine!!! Accuracy as a result was supurb.
225 yard shots on half grown ground squirrels was easy, and further.
I killed quite a few coyotes with the 77 that had the all weather stock on it, same 40g speer spire point. I shot AA1680, but today I would start off with little gun.
My wood stock 77, I turned into a K, tad more velocity, same level of accuracy. I had Pac Nor put a barrel on the wood stock, got the same accuracy as the factory barrel...$700 down the drain!
I really enjoyed hunting coyotes with this round and all weather rifle. I hate that I traded it off.
I got rid of the 77 Wood stock in 22 K hornet, Sako AI custom 17 MachIV, custom 17 Rem, Kimber 25 M switch barrel in 22 K hornet and 17 K hornet all at the same time, down sizing to 223 in Rem 788 and 22/250 Ai Rem factory rechamber.
Some things seemed to help hornet accuracy,
touch the lands with the bullet(40g Speer spire point)
Glass bed with free floating barrel
Trigger job
Lee factory crimp die
Good luck!
