I know. I need to lose about 20 pounds but I'm struggling with the most important piece.... Diet.

annndddd... it got pushed until 1:30.

By "hootenanny", do you mean dentist?

no, the meeting...

[TheBelly]

And my briefing is done! Sweet!

now to the dentist. Ugh!

wait a sec: new turret press is at the front door!!!! Woot! Unboxing video tonight!!!!

[mcjhr]

I don't know what that is, but it sounds awesome.

Congrats on the new press Belly!! Can't wait to see the operation of it and your opinion!

To what end? The scope base is steel and the scope is aluminum if I researched correctly (SWFA SS 10x MRAD). This general rule of thumb only really applies to clamping strength (when referred to firearms use), as in, you wouldn't want to put steel rings on an aluminum scope base because the scope rings are harder and will deform the aluminum scope rail when tightened down.

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.

Well, I thought we'd already covered this, but I think the LT104 is an alright mount...

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!

Day? When will this WEEK end?

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.
