Ruger 77 - 416 Rigby Users - Need Your Help
      #83628 - 07/08/07 10:47 AM

First the good news: I'm getting ready for my first Cape Buffalo hunt which will take place in August of '08. I'll be using a Ruger 77 in 416 Rigby with a Bushnell 3200 1.75 x 6 scope in Warne QD rings. I just got back from the range, and I shot 3 shot groups, with 3 different loads. Load 1 was loaded by a friend who does all of my reloading, and used the 410 grain Woodleigh Solid. Load 2 was Norma Factory Ammo using the 400 grain Swift A-frame, and load 3 was the Federal Factory load using the 400 grain Barnes TSX. All 9 shots were in one ragged hole that measured 1.1 inch, top to bottom, and 3/8 inch side to side. The solids all hit in the middle, the A-frames at the top of the group, and the TSXs on the bottom. All shots were off the bench, using Cabela's version of the lead sled, with a 25 pound bag of shot sitting on it. I couldn't be happier with the results.

Now the bad news: after testing for load accuracy, I decided to shoot a few rounds off hand, standing. I only fired 3 shots off hand, because on the second and third shots, I got wacked between the eyes with the scope. Fortunately, no blood was spilled, probably because the scope has a hard rubber ring around the rear of the tube, but I look like I got stung by a wasp - all swollen, and puffed up. I originally wanted to use a Leupold 1.75 x 6 x 32 scope, but it wouldn't fit in the rings. I need to find a different scope, because I'm afraid if I continue to use the Bushnell, I'll develope a nasty flinch. Any suggestions on what scope I should look at that will give me the eye relief I need?

Try a Burris.

The eye relief is too short for me. I need at a minimum 4 inches.

Mike
You might try a Leupold 1.5-5. I like the heavy duplex.

Also you should mount the scope far foward. If your neck is already stretched out before you shoot there is less of a chance for your head to get a "running start" toward the scope.

If your neck is already stretched out then your head will recoil back with the rifle.

Also maintain a firm shoulder until after the recoil. If you relax your shoulder just as you shoot your shoulder colaspses allowing the rifle/scope to travel back toward your head.

Scope foward, firm shoulder, hard cheek contact with the stock.
Your whole upper body should take the recoil.

I like my Burris 1.75 x 5 Safari with posilock. The eye relief is supposedly 3.8-4.5 inches and I have never got whacked by my "semi-lightweight" 416 Rem mag at 9 pnds with scope.

NE450No2 is quite correct on shooting the gun.Pull the gun hard into your shoulder and have your head slightly forward to focus.Lean into the shot and use a shooting shoulder aid as well.When I don't do this big bores can hurt!!

Some of the new german scopes have more than 4 inches of relief but they will cost more than the gun!!

Have fun!!

hopdoc & NE450No2 - you guys are a riot ! The Bushnell that is now on the rifle is as far forward in the rings as it will go. I've never been wacked with a scope before. I handle my 375s easily, but stepping up to the 416 is IMO definitely taking it up to another level of power. The rifle has a decelerator pad on it, and I didn't mind it on the shoulder, at all. I'll try to remember both of your suggestions on my next trip to the range - after I get the new scope.

I hope that when you change the scope you also change the rings. My objection to variable scopes with large objectives is that the require the use of medium to high rings to clear the barrel. This plays hell with the abilty to snap shoot with the rifle.

A heavy rifle should have the scope mounted so that the shooter's head position is as close to his iron sight head position as possible. Practice with the rifle at the International Skeet "ready position", with the stock touching the point of your hip bone. At someone else's signal, mount the gun to your shoulder. If all is well, you should be looking straight down the center of the scope, with your face firmly down on the comb of the stock.

One of the handicaps of using a higher power scope is (1) shorter eye relief and (2) smaller exit pupil. The exit pupil is the little circle of light you can see on the eyepiece of your scope. Your eye has to align with this little circle for you to be able to see through the scope. The size of the exit pupil is determined by the size of the objective and the power setting of the scope.

If you are using a scope like the Leupold 2 1/2-8X32 VariX III, with the power set on "8", then the exit pupil is 32/8=4mm in diameter. If the power is set on 2 1/2X, then the exit pupil is 32/2.5=12.5mm, actually larger than the pupil of your eye, and very easy to pick up, which can be important in a tight spot.

Benchrest and target shooters use up to 32X scopes with 50-55mm objective lenses, which results in tiny exit pupils, but this is not a negative factor, since they have all the time in the world to line up with the scope.

First of all, I'd like to thank everyone for their comments and ideas. I bought a Leupold 1.5 x 5, illuminated reticle, with a 30mm tube. I got rid of the Warne QD rings, and mounted it in Leupold Bases. This setup gives me a full 5 inches of eye relief. I took the rifle to the range this afternoon, and I must say that I'm very happy with the outcome. I can get my fat face down on the stock, and the rifle is much more comfortable to shoot now. I fired two, three shot groups after resighting, and 6 shots were in one ragged hole at 75 yards. I have the rifle hitting 1 inch high at that range.

--------------------
May the best days of your past be the worse days of your future.

I sent that same scope to Germany to be mounted on my Krieghoff Ulm 9.3X74R O/U double rifle which is in the process of being stocked to my specifications. I had not had the opportunity to try it beforehand, but having used the 1" model for some time, I was sure I would be pleased with it. Nevertheless I would be happy to hear any more comments you might have about it as you gain more experience.

From your description of your first trip to the range, it sounds as though your problems have been solved.
