Too little clearance? New scope mounted.

[Morkai]

Evening all,

I know scope height has been covered before but this is a question specifically for the clearance I have here.

This scope is on my 45-70.

Just mounted it this evening with a set of mounts that give me clearance above the ghost ring and a good cheek weld.

There is very little clearance on the rail.

Do you think this will be ok given the 45-70 has a short, heavy barrel (may not flex too much) and the obj lens is still over the picatinny rail?

Thanks

Clearance is clearance - all is well!

Cheers, my calculations went well then!

So whats the problem, I shot a lightweight 30-06 for years with 5 thou clearence between the barrel and the scope

Looks fine to me.
Not a dissimilar amount of clearance to my own:

No problem.

I had looked at a few articles and what not that mentioned that some resonance and flex in the barrel may cause issue, as I had no way of questioning what was written there, I thought I would ask here for feedback.

Also, how did you even measure that as it's like 0.12mm (a human hair), just curious?

Thanks, VSS.

Possibly a daft question, but why is the rail sooooooo long?

Only be a problem if you want to fit a front end add on Thermal/NV and looking at the calibre that seems unlikely

Looking good.
Any minute now….

With a feeler guage they come in metric and imperial

Probably so you can mount a scout scope very far forward on the gun.

Ah, I see, of course. Cheers

Nah, wont be doing that, too skint now for a good thermal anyway and all those Pard NV attachments look very cumbersome.

This can help you if you’re unsure. User input needs to be correct of course

Did it come with that fitted then? Apologies I assumed it was after market fitting…

The SBL version, which is this one come with that rail as standard.

The Trapper version comes with Skinner sights and a dovetail type setup.

As takbok says " clearance is clearance ". I think the closer the better, as the line of sight is as close as it can be to the centre of the barrel. This helps with bullet drop, and accuracy. Well done.

Bullet drop and the 45-70 are very good friends, haha.
