Rifle Scopes What is minimal scope bell clearance??

[trophyhunter]

Ok so I'm trying to use the new search function and not coming up with any results...

I'm trying to mount a 5-25 Tpal that I got from Lazy21 (great guy & price by the way) on my DTA in a DTA 30moa mount and I have 2 minor issues

1st With the scope all the way back in the mount the elevation knob comes into contact with the top of ring. I raised it 1mil and that eliminated that problem as I have yet to zero the rifle I won't know if its affecting anything

2nd On the objective bell I have only 8 thousandths of an inch clearance. I used my feeler gauges and it reads .008
Will this be enough ?

Thanks for any help

Technically it isn't touching, but .008" is about as close as it gets. Might be OK, but if it were mine I'd get slightly taller rings.

.008" is probably not adequate. Have you ever seen a slow-motion video of a scoped rifle firing? The scope wiggles around like its made of rubber. I'd be concerned your high $$ scope is going to smack your barrel during recoil.

I am concerned about this but haven't seen the effects of a 308 in a DTA chassis system.

The mount I'm using is a 30moa could a 20moa alleviate my problem ?
Does anyone have measurements of the DTA mount ?

Thanks again for the help

I can understand the barrel being a problem if it were that close. But it shouldn't be a big deal with the rail of the DTA chassis being that close. Is that .008" with the plastic flip up or the actual bell of the scope?

Dave that is on the actual bell as I didn't have room for the flip-up

Oh wow. With that long of a scope I would think 10MOA would make a huge difference at the bell. Wish I could help AND owned a DTA!

I use Ultra High MAX 50 Badgers with my 3.2-17x44 T-Pal on my monolithic 0MOA AR10. I use Badger High MAX 50's on my AX chassis and 20MOA base. The bell barely clears the extension with the flip up attached.

its rather difficult to find 35mm DTA mounts in 20moa and Unfortunately I don't think the Spuhr mounts will fit the Tpal's
