.243 Ruger M77 MkII International, Best Ammo??

[waynewjw]

Any of you guys out there shot or shooting with an International model? With the 1:9 twist, whose ammo is performing best for you out of the 18 1/2" barrel. Should the gun be favoring the heavier grain bullets - 95 or 100 grain, or do some of the light loads work better.

I will work up a load for this rifle, but I'm hoping to save a few visits to the range based on some feedback.
