Remington 700 Bedding Pillars

[RangerPark]

Great work. I am doing pillars this week. Any comment on range results and action screw torque settings would ne welcome.

Thanks!

This rifle was 1/4 - 1/2 MOA without the bedding, most of the groups in the .300 range. Eventually the action screw holes started to show ovalisation and the stock compressed at the front screw where I used a washer to fit the DBM. I stopped shooting then and have been working on the bedding for the last two weeks. I will have a range report within the next two weeks.

As for torque McMillan recommends 40-45 in lbs and I'm at 45 right now, dial indicator on the barrel, no movement whatsoever.

I have a 40 year old wood stock that let go a week ago while shooting in hot weather. The action screws refused to stay put and the stock crush was already a known. Its 1/4 MOA at 200 yds and sub MOA at 500 yds. But POI went south and that's when I started looking for solutions. I will use 3/8" brake line for pillars and upon close inspection will cut them long to correct for shrinkage of the stock causing magazine binding.

I hope to preserve the accuracy and trust POI will remain stable, last week it drifted 1.25 MOA at 200 yds in one outing...unaccept
able!

That's exactly what happened to me. Devcon will solve the problem. I actually don't think you need a metal pillar in there, but probably safer that way. I'll be shooting mine first before I get some actual pillars in there.

Still working on loads for the rifle. The bedding did change the rifle's harmonics a bit, just fine tuning. Last weekend's .313 MOA at 300m was promising. As you can see from the .621 group, user error is still a factor. It was raining that day too. Current torque is at 50 lb/in, I'm reading .005" barrel shift when I torque the screws. I will likely re-open the screw holes, insert custom pillars and touch up the bedding over the winter. My goal is less than .002" barrel shift when I torque the screws.
