Scope bell to mount.. how close is to close

Post by Huntnfish » 20 Jun 2020, 5:20 pm

G’day all just finished fitting a new old stock VX2 2-7x33 on my new mod 70 ftw in 270 win used Talley lightweights in low with extended front to get proper eye relief for me everything went great came together nicely until I stood back and looked it and noticed how close the scope bell was to the front of the scope base anyone here have any similar situation to this I measured it it’s between .7 - .8 mm gap is this to close or should it be fine any input from someone who has had the same problem would be great don’t particularly want to keep moving the scope forward I’m almost maxed out the eye relief on x7 any further and I will have to start crawling the stock

Touching is too close, not touching is perfect. You appear to be perfect.

If it was touching, you could grind a little off the base for clearance.

Nah...its just those cheap chinese Vision King's that flex... :lol: :sarcasm:

I think SCJ is spot on...nothing wrong with what you got there.
I wouldnt want to be moving that scope any farther back though... :unknown:

The scope would only move forward under recoil. But it won't move anyway. I have a scope that I can only get thin paper to pass through the gap.

Kellogg’s cornflakes is the answer for me. If a piece of cardboard from the packet can pass thru the gap all is well

I used to think that I should mount as low as possible and I’d go out of my way to do so (ask me how many sets of rings I have lol) , as it would ultimately mean a more accurate line of sight for a longer distance, but then MM showed me some links where the difference was mere millimeters...

If after some use you see a shiny mark developing on the scope bell or the mount base then you will know that you should consider putting a bevel on the base.
From your picture it appears that the objective bell is well supported due to the front ring being so close to the beginning of the tapered expansion of the tube but in this shooting game you never can be totally certain.
I would normally suggest that about 1/8" is a suitable minimum clearance.

Thanks for the input I think I might just do that straight away I don’t want to waste a trip to the range only to have to go again cheers
