My son has a remington 700 in 243. I reload 58 gr Hornady and 100 gr grand slams for this rifle. The two loads shoot about 6.5 inches apart. A friend suggested I try using two scopes with a quick change mount. We often load the 100's for a hunt, then will spend the afternoon shooting at squirrels. Any Suggestions on a quick change?

Welcome to the forum.

Personally I think that would be a big aggravation.... done any experimenting with different bullet weights / velocities to see if you can regulate one load or the other?

If you slow down the one that hits low, you might raise the point of impact a little.....

Suppose I got lucky, but found a good combination of 100gr. bullets and 75gr. HPs in my .257 Roberts that shoot to the same point of impact at 100 yards.

Might suggest a Mil-dot reticle scope. The dots can be used for the different groups and you'd only need the one scope without the hassle of having two. Besides, having the two scopes return to zero after removing and reinstalling is an ify proposition.

I think the quick change would be a good idea for that. I would go with Leupold mounts.

Use these rings with Warne steel bases.

This would be a very strong set up.

Violation of the K.I.S.S. Principle. 15 yard penalty and loss of down.

I wouldn't dink with a second scope. What if you drop your pack with it in it? Fall on it? Lose it? I'd be looking for loads that regulate better. Maybe a different bullet in the same weight. A different powder. Maybe even a velocity change. That way, you have two different types of ammo with you and the one rifle with the one scope for both.

Doc I'd be interested in the results of your hunt with the 100gr Grand Slams. A hunting buddy uses 'em in his 6mm. Seems everything he's dropped is bloodshot bad from the fragging. The last example I seen while helping process a whitetail buck... shot behind the right shoulder, hit a rib going in and fragged the bullet into the neck, offside shoulder, and loins. No exit wound and no big bullet pieces recovered.

Just wondering if it's bad luck or a normal thing with that bullet.

I have a few rifles with QD mounts and three of them have two scopes each. they perform very well as long as I do my part. I don't use the rifles with two scopes for different loads, I use them for different applications. Usually a big (heavy) scope for sitting in a blind where dawn/dusk are key times, and a lighter scope when I hunt on the move. Here are the QD systems I use and would recommend:

Leupold QR 1 piece base and rings
Talley with levers
Warne Maxima series
Steyr SSG (Steyr lever mounts)
Leupold Detacho system

Doing your part means you should lap your rings to remove the stresses, and tighten the levers consistently. I park the levers pointing straight at each other if I have a choice (Leupold, Talley, Warne yes, Steyr no). I always snug the front first, and tighten them as much as I can with two fingers.

Having an extra scope on an expensive hunt is cheap insurance. Weight limits (usually 70 lbs) prevent taking a back-up gun if you fly, and I have been on hunts where scopes were trashed. I like to remove the scope when traveling and wrap it up in my clothes. A good hard case and a soft field case also a must. I know of cases thrown out of airplanes onto the ground, run over, and otherwise trashed in transit. I check zero upon arrival if allowed.

Like any type of equipment you rely on, prove the reliability to yourself. Bench shoot with a SOLID rest and remove the scope between shots. Compare those groups with those shot without removing the scope. Shoot regularly, not just two weeks before the hunt! Hope this helps, and good luck!

Monty F: Wish I could tell you the answer. We have only used the gun to shoot varmints on our ranch to this point, coyotes and squirrels mainly. Over the last year we have had pigs move through, some of which I have taken with my 06 (180 gr Nosler). My son has been with me a couple of times, but we did not see any hogs, hence the shooting of squirrels when we can't find pigs. I have not bothered to check the bullets after firing into a coyote. I will next time and let you know.

I've done exactly as you propose for many years now. Zero a scope for a particular load, remove it and zero another for a different load. I use Warne or Leupold QD's and they always return to zero.
