Long range Scope That Can Handle Extreme Recoil

Postby Dylan Mulie on Sat Oct 14, 2006 2:27 pm

I Have a winchester mod# 70 Black Shadow chambered in 300 win mag it has a synthetic stock and an unusually long barrel as a result it kicks like no rifle i have ever seen eaven with light factory loads i had the rifle topped with a m8 fixed4 leupold scope and eaven with the reputation of this scope to handle heavy recoil my rife has punded the crosshairs right out of it several times and i am tired of sending it away 4 repairs can ayone recomend a 3-9 or similar scope that can handle the punishment?

Hi,

If your Leupold is breaking, I'm curious if it is mounted correctly. If your rings are not aligned it could wreak havok on even the strongest scopes. If there are more than faint marks on your scope when you remove it, this is the case.
If you don't want another Leupold, try this Bushnell Elite 3-9 timothyjamesharrington@yahoo.com or this Nikon Monarch http://www.opticsplanet.com/nikon-rifle ... -9x40.html . I would put on a 3.5-10 Leupold http://www.opticsplanet.com/leupold-var ... scope.html .

Rifle with extreme recoil???

Postby MrGman on Tue Oct 17, 2006 11:24 pm

I am kind of suspicious about the rifle having extreme recoil as being normal. As I understand it a longer barreled rifle should actually have less recoil than a short barreled one. For one its heavier. Secondly there is no blast of escaping gases still burning as the bullet exits the barrel causing rearward thrust, because all of the powder is burnt and the gas is no longer expanded by the time the bullet exits the barrel. I have never felt greater recoil from long barreled rifles compared to shorter ones of the same caliber. Just the opposite

I suspect that your barrel has copper fouling build up that is causing excessive pressure and that is the cause of your "heavy" recoil issue and not the length of the barrel. I have seen this first hand in rifles chambered in 223. Specifically that there was an area from 3 to 6 inches in front of the chamber that was rough and building up with copper fouling in a low quality barrel that had a lot of rounds through it. The person thought they were getting out all of the fouling with cleaning but were not. This was a semi auto rifle that got to the point that it was stripping the rims off the cases because the bolt was slamming back so hard and fast from the pressure build up that the case would not come out immediately after being fired, but after cooling down for several seconds the case would drop out. The problem was solved by making a lead slug in the barrel a process I am not going to go into detail here, then pulling it out, putting grit powder on it and then runnning it through the barrel to fine grind and polish out the copper fouling and rough spots starting with 320 grit and going up to 600 grit powders. Shooting the same type bullets through this the barrel after this special cleaning/polishing process actually fixed the problem. The pressures came down, the bolt came back with normal speed and force and pulled the case out rather than rip off the rim. Accuracy came back up as well.

High velocity calibers have a tendency to create more copper fouling in the barrel than lower velocity larger bore bullets. Copper fouling causes more pressure but not necessarily appears as higher velocity at the front end in case you are monitoring with a chronograph and don't see any evidence to suggest that something is changing.

You may want a gun smith to actually take a good look at your barrel for you and see what's happening.

There may be other problems as well that are causing additional shock to the receiver when you squeeze that trigger such as the bolt not really having a good tight fit on all lugs into the back end of the chamber area of the receiver, such that when the primer sets off the charge the bolt is actually being slapped back, possibly not in a directly rearward linear motion but offset due to uneven lug contact and that bolt "slap" is causing a real undue shock in the receiver that is not normal. Again, I would have a gunsmith take a real close look at this rifle before I simply threw another scope on top of it. I find it very hard to believe that you would have multiple Leupold Scope failures. 300 win mag isn't that powerful. People shoot 375 H and H, and other ridiculously powerful cartridges all the time and don't have problems.

If the gun really does have very high recoil because it is so light weight, then perhaps you want to put a recoil reducer such as those sliding Mercury tube plugs in the stock to directly counter that recoil pulse. There are several ways to tame the beast but first make sure everything is okay with your rifle.

A friend had the ejector on his rifle come back and bury itself 1.5 inches into his face before he knew he had a problem with his rifle. Don't assume that just because the rifle appears to be working that it is operating correctly.

If you are really sure your rifle is functioning properly try the top of the line Burris scope.
