Thank you guys, 2 days ago I began working on this 788 rifle, it was a mess. It did 25 shots into 10 inch group.
I took the barreled action out of the stock and found the front sling swivel stud was making contact with the barrel, there was a wear mark on the barrel.
I ground down the stud and nut and free floated the barrel channel. Also I glass bedded the front recoil lug.
I did install a Timney trigger too.
Back to the range yesterday and shot some handloads with Varget and 150gr Sierra SP. The came down to 1.5 inch at 100yds.
Today at the recommendation of friend I tried some 165 gr loads, he gave his specific load info, I measured and copied the ogive of his match loads. The 788 did not like them. As a reference I brought along some of the best 150grs loads. They shot the best in the rifle.
The 165 gr bullets were:
Nosler 165gr AB
Hornady 168gr ELDM (my buddies match load)
Hornady 165 gr SPBT Interlock
For this 308, I only have 3 cans of powder to work with, Varget, H-4895, and IMR-4320. I have only tried Varget at this point.
My primers are limited to Federal 215 Magnum Match and CCI-250. I wish I could find some standard lg rifle primers.
The brass is Hornady, they have trimmed to length, primer flash holes are deburred, and the outside neck diameters have been recut uniformly.
