338-378 Weatherby Magnum broke another scope.

Those dinky millet or whatever bases are on there definitely look like a weak point. Are they aluminum?

Like mentioned above, are you shooting this in a lead sled, or is there something between the rifle and your shoulder for recoil? Setups like the lead sled are scope killers, as they do not allow the rifle to recoil, instead of your shoulder absorbing most of the energy, the scope takes most of it.

Zero experience with the lead sleds so correct if im wrong, but wouldn't this not happen in a fixed rest as the rifle needs to recoil backwards for the scope to move forwards(stay still) in the rings? Are the lead sleds not as solid as Im thinking, or does the give of the recoil pad allows just enough movement or am i missing something altogether?
 
Me'n Mr. H lost four scopes in one outing with using our Lead Sleds.
Mr. H sold is pronto and me not long afterwards.
One scope maybe, but four at one outing.............no coincident on my way of thinking.
And not slouchy scopes either.

Yes after watching some videos of them in action I notice they have a noticeable amount of movement, enough to slip in the rings for sure. I was under the impression they were more of a vice type device like a hog saddle. The compression of the recoil pad alone could cause it.
 
After you change rings, might I suggest using a Zeiss Conquest scope as they are used almost exclusively for the 300 Wby Mag calibers and up according to guys on the Weatherby Nation site. Using one on my 300 Wby Mag with no problems. Also has in excess of 4 inches eye relief!
 
Hi all

Thanks for all your awesome input. Really appreciate it

So I replaced the 9$ weaver 2 piece rails with a 2 piece steel leupold rail set. I replaced the millett 2 screw rings with vortex tactical 6 screw rings

I really would of liked to go with the NEAR Manufacturing parts, but they are out of my reach for now, maybe in the spring hopefully

Also made a lapping bar for my rings

Sightron technician is absolutely adamant that I did not break my S3 and they will walk me through testing my scope before sending it back
 
Those Vortex tactical rings you got are still junk, no better than what you have been trying, if it’s Vortex you want to use you need the precision mounts, Seekins makes them for Vortex.

Not trying to be rude, just being honest, you need to suck it up and get some good rings, some NF 6 screw, ATRS, Seekins, list goes on others have mentioned more, what you bought are cheap china junk yet again.
 
One of my first kickers....2004ish was a M700 in 375 Rum....Vx3 in 1" TPS. Never a problem, this setup stayed while all my other Leupold left. Old Cal in Langley insisted basic weavers would hold my Zeiss diavari on a 300 rum....wrong. I do like the weaver tactical rings, lots of surface.
 
long time ago when i was still doing that we contacted Leupold for what what of rings needed for a weatherby Mark V in 30-378 and 338-378 with the factory brake and it was always dual dovetail rings and bases suggested ... never moved. spoke at the range and he was still using what was mounted for him 6 years ago never moved and the scope was still a leupold.
 
Well I just took the vortex tacticals off the rifle, going to return them,

Instead of nightforce, seeking, or atrs, would leupold mark 4 rings be good for my 338-378 setup?

Regards
 
I have a t3 lite in 300wm that was loaded up pretty hot. it moved scopes with regular rings but after switching to burris signature z rings I haven't had a problem. not sure if they are any better or if it just worked for me
 
If you had a one piece picatinny rail you could try using three or four rings depending how much room you have. I highly doubt Mark4 ring will be any better than Vortex, Seekins or ATRS.

Leupold uses a simulation of a .50 Cal for the standard of testing is what I read.
I'm curious as to what is being used at the range too.

Have you sent an email to Leupold and asking them for some guidance ?

I watched some guys years ago arrive at the range with this cannon and they immediately (upon cease fire that is) head out to the 300 yrd mark on the Barnette Highway Range and proceeded to put shots in the 10 ring .
They finished a box of 20 rounds and smiles all around.

Turns out it was one of he first 338-378 Wby Mags in Western Canada...they own the store on Rupert Street in Vancouver.
Dont recall the scope so thats an unknown...as are what rings it was mounted with.

Maybe a set of rings with more surface area..that have 4 screws per ring...the brand name escapes me now...

Do look forward to the solution to this interesting dilemma.
