Ruger M77 Hawkeye action screws

[prarie_boy]

Anyone happen to know what the specs are for the ruger M77 front and rear action bolts trying to get a set of headless bolts for a bedding job.

What i do is take a action bolt with me.....find a nut that fits, buy the mating bolts to the nut, check when you get home. Buy them fairly long and cut the bolt head off with a grinder or saw.

According to Bolt Action Rifles by Frank de Haas, the front screw is 1/4-28 and middle and rear screws are 10-32.
