There is also a school of thought that the rate of expansion/contraction dependent upon temperature necessitates the use of like materials when clamping rings to a base to avoid any potential for POI change. Granted the scope tube is going to be Aluminum, but should be less affected by temperature swings. Do I have any empirical evidence to support the claims? No, but I read it on the intarwebz so it must be true.

I never said it wasn't. In fact I love the QD LT-104 mount and have one on my Sig 716Patrol hosting a SWFA scope. So much so that I'm looking for another.

That said, I personally wouldn't mount one on a bolt gun. Perhaps the QD LT-158 that's a tad lower.

Man will this day end already!

True, any difference in CTE between the components will affect the accuracy. Just looked it up and the CTE of 7075 alum is roughly half the CTE of 1215 steel. If I wanted to really keep track of actual POI changes, I would zero the scope at different temperatures, from 0*F to 100*F and make a lookup table to change my zero depending on the temperature and CTE properties of the scope, rings and rail. However, I'm not that OCD... But that's not what my wife thinks.

Just booked airfare to Chile. The final cost for my single ticket was $200 more than what it cost to for both tickets for wife and my tickets to Hawaii.

And then ensuring the POI difference is due to the mounts and not the ammo.

What'z goingz on ? Are you Ho's on vacation ? Gets out on dem streets and makes me sum monies...... (Bitch Slap smiley Here.)

Hey, us hos have earned a break! We've been ho'in hard, what more do you WANT from us?!
