Scope mounting to maintain zero

[Formidilosus]

Yes , with Burris Signiture XTR rings.
They will not self centre if assembled dry.
Form has mentioned that he has broken multiple sets, and I could see that happening if they were degreased and tightened dry.

I haven’t had the Signature XTR’s break- just the newer regular version of Burris XTR pic rings.

Also a mate was very disappointed in his Spur mount not returning to zero, until I told him about wet assembly, that fixed his problem.

i have a couple sets of xtr signature rings in service, all assembled dry. they've worked well, including through drop testing.

They come lightly lubed, did you degrease them?

Yes, with acetone

Yes, with acetone

Getting ready for the SWFA 3-9x HD to arrive. I don't think I'll run out of acetone......

Until your wife finds it. Mine just stole 2/3 of the can

I’ve mounted 5 scopes in my life- so certainly a beginner and confused. I recently bought a few rifles tikka/Sako in .243 & .223. Two have Nightforce scopes and rings. NF rings are torqued to 25lbs. The others I will use UM tikka dovetail rings (4 screw) and will mount Maven rs1.2 scopes.

For the tikka/um rings/maven set up, what is the best torque for the ring caps? I’ve researched the forum and find answers ranging from 18lbs (first instructions on this thread from @Formidilosus ) to 32 lbs for thick-walled scopes. Other threads note 25-30 lbs. Maven says 18, from UM I’ve found a few different values. Appreciate any clarity/guidance y’all are willing to give a beginner.

I do 25in lbs on my maven and Swfa with UM rings. No issues after a year or two and ~1000 rounds dialing.

I just went digging for this recently as well. Forms answer below on base screws - different than um specs on their website. And has said 28-32inlb for ring caps which is basically right at um specs of 30inlb

50in-lbs is not enough to hold the base in place. Degrease everything, thread lock, push forward on the ring against the pin, torque to 60 or 65in-lbs on the base screws. Go shoot.
