1/3 of 1 degree on small screws = no impact.
Common sense would dictate that you cut the screw seats at the same time. As they have very little purchase to begin with.


and he has big trouble. IMHO.

What is common sense ? They don't seem to make it anymore. LarryCommon sense would dictate that you cut the screw seats at the same time. As they have very little purchase to begin with.All he need is a few thousands of movement
and he has big trouble. IMHO.

I know what it feels like to have gun problems but, I can't resist. I was explaining something to my grandson and told him, "it only takes common sense". He said, "grandpa, they haven't taught us that in school yet"!!! I turned my head so he couldn't see me smiling. True story.What is common sense ? They don't seem to make it anymore. Larry
Not funny but is the truth . LarryI know what it feels like to have gun problems but, I can't resist. I was explaining something to my grandson and told him, "it only takes common sense".

I never have seen a gun shoot that bad. Without something being loose .12 MOA movement at 100 yards is a bunch, much more than some some screw head not quite being at the same angle as the scope rail.
Something catastrophic has happened and it's probably rather obvious. Take a deep breath, regain your composure and look at each part of this
objectively.
Thanks for all the good info folks. I spoke with Gary too. He was a great help. I'm going to opt for bedding with JB weld. By matching the base I opened it up to some slop in the mounting slot. While it seems tight, there is actually some space with the screws heads for movement in the horizontal plane. I just don't get how it could move enough for 12" of vertical at 100 yards with two different scopes but there is no other explanation.
I'll post results next week. I'm going to sacrifice two goats and a chicken before I bed it just for good luck.
I didn't see anything about vertical he said a 12 group . Larry12" of vertical is 12 moa or 1/5 of a degree. The tangent of .2 degrees is .0035 so movement of .00175 in 2" would give you that. --Jerry

I seen 3 screw holes I thought was strangeOK. So 12" in any direction is still .00175" movement at the screw assuming 2" apart. If 4" apart it is .00088" of movement. --Jerry
I own an excellent Elisio R5 with a 700 action chambered in 6mm BR. The gun has been a proven performer, even if I am only a so so wind reader and semi hard holder.
I was going to use the gun for a recent 1000 yard match at R117 on Pendleton when I discovered I didn't have enough elevation with the current base and scope combo to reach out that far.
After I shot the match with another gun I took the base off the Elisio and milled about 0.034 off at a tape to get me the 20 moa I was short.

The first range trip to test the gun was a disaster. The gun was shooting close to 20” groups, at least with the bullet holes I could find. There were some machining marks on the bottom of the base, and I suspected those caused the base to move. I once again took off the base and carefully surfaced it.
The base is super flat, and seems to tighten down tight. However, upon testing it again today the gun is shooting 12” groups at 100 yards(more or less, usually more). I tried a different scope just to make sure the scope wasn’t the issue. The problem doesn’t change with scopes!!
Needless to say, I am disraught that my BEST shooter is now my worst shooter, and I am the one who ruined it.
My question is, would it be possible to bed the mount to insure a solid fit into the R5 chassis? I am almost certain the base is moving, and it’s also the only variable between ½ moa performance and the new 12 moa shooting.
Save your money and get a new barrel .I am probably pushing 2000 rounds in the barrel. I am not sure what the first owner shot, but he said maybe 500. I am going to slow the load down a bit to see if that doesn't help. Right now I am at 2910 fps with 29.5 grains of Varget
Measure the diameter of the Noslers. I have the 105 CC's, mine measure .2423. They shoot very well in my 6br, but they are definitely undersized in comparison to SMK's.
