Scopes at Raton

On another forum, a newbie member going by the name of James Kelby implies that the NF 15-50 scopes were going belly up at Raton in great numbers.

Did any of our team members hear anything along those lines or is the story a very nasty bit of commercial sabotage by a competing supplier?

Correct me if im wrong but Kelby is a distributor for march scopes is he not?

Dave hit the nail on the head in his reply. All scopes will fail. They are mechanical items. Sometime mechanical items need fixing. Its what a good warranty and carrying a spare scope at a major prize shoot is for. I reckon its probably a bit of a dig at the competition. I wasnt there but when you have Larry Bartholome AND Dave Mc both saying there was alot of other stuff going on that could affect POI than just a scope, I would be inclined to believe them.

Kelby was pretty specific, saying 20 instances of failure. I am surprised that such a claim would be made by somebody of such high repute in the accuracy game.

I know it's a video of 50BMG recoiling at +70ft-lbs and a 308W is about 16ft-lbs, but it gives you an idea of the harmonics the scope endures each shot.

Scopes might be tested to 375H&H recoil or even 50BMG recoil but there is still a limit as to the number of times they can handle the recoil. The old spring recoiling target scopes of the early 20th century start to look more durable.

I also confirmed the YouTube video of "Range Time with Cory & Erika - Erika shooting Serbu BFG-50A .50 BMG" has nothing to do with scope flex. :wink:
