My .300rum has a little better than 300 rounds through her now and still shoots the lights out with the burris ff2. The ballistic plex recticle has been perfect to 500. No dialing it up n down just range it select the right stadia and send it. At less than 3 bills what a deal. (only if it dosen't break) Check your rings and bases,action screws etc. If that aint it. Let me know if you would how the warranty dept treats ya.
My Lupy VXIII bit the dust somewhere along the line. I could only maintain groups from 0.75 to 1.5 and expected more from the rifle, but zero usually held well from trip-to-trip. Ocassionally I had some zero shifts, but blamed them on the weather conditions and the loads. I put my Super Sniper 10x on the rifle and had similar, or worse results. Finally, when I pulled the scope off of the rifle I noticed that the internals were rattling around in the scope. Sent it in to Luepold, got it back a few weeks later, but now the rifle is with the smith, so I'll have to wait to see if it holds up. The rifle that the scope was on is a 338 Lapua without a muzzle brake.
I've had a Leupold 3.5x10 and a 6.5x20 on my 300 Rum for the last 2 years without a problem.
When looking for a scope for the RUM it is a good idea to look at the eye relief on the scopes you're considering, particularely at the higher magnification. A few tenths of an inch can make a BIG difference in that half moon above your eye. :>)
Weaver Grand Slam--- for the money, extremely amazing! I have two, a 4.5x14-40 and the 6.?x20-40.
The 4.5x14-40 has been abused with a 300 Winch. Mag., and 2 (two) 300 Ultra Mags, one without muzle break and the other with a muzzle break. Many hundreds of rounds through all these rifles not counting the mild 308 Winch. Two hunting trips outside of nevada, one to colorado and one to Idaho. Some real hard driving and beating the Grand Slam has taken; but not only the zero never changed, its amazingly accurate tracking small turrets are worthy of respect. Using 20 moa bases and burris rings, my youngest son...Read this link. When it comes to a lower priced variable and extremely reliable scope, it has to be very hard to find a better one.
