hard on scope

[herman]

First I have had my hunting load now for the last 2 years and don't want to change it.But when I have time I like trying any loads that come up here to see how they do in my savages.
Yesterday I decided to try IMR 4198 (68 grs) 250 sst,and 110/322,(14/61) Shot good for the first time all went into a 3 inch circle.Found out that these loads were very hard on my Buriss 4.5x14 B-plex fullfield11 All ready had it worked out using the b-plex to 300 yds.On the sixth shot my scope blew,went from clear to milky looking.Looked like the glass had shartered inside.I thought the load I used kicked pretty good but I believe these loads kicked more.
What scopes do you fellows use on your savage shooting these hard kicking loads?
I have a buckmaster 3x9 on the other savage and it has been doing good for 2 years now,But I did break the cross hairs out of one of them shooting 150 grs of T-7 year before last.Now that load would make your teeth rattle.Didn't take but 2 shots.

8-)The faster the bullet goes the more it kicks. When reaching 2400fps or faster then you have recoil there's no doubt about it. This is the reason I've never had much interest in supper loads (a 250 grain bullet to 2700fps or faster) for they do more than just go fast.

The amount of recoil can be predicted by asking what rifles shoot a 250 grain bullet faster than 2500fps? Not many do but those are powerful rifles. The 358 Norma Magnum comes to mind as well as the 375 Holland, 340 Weatherby, 338 Winchester and 338-06 all big kickers.

I suggest you use a scope made for some recoil like a 2x7 Leupold or similar Nikon. One other thing I've found is the mounts are just as important as the scope. That's why I like steel Weaver style and Millit angel-loc rings.

:)I've used the Sightron 11 42MM 3X12 MD(non-adj obj) on 2 of my ML-2s, B&L 4200 2.5X10, and Leupold Var-X3 4.5X14 50MM on the others. Many, many shots and no problems with any.

it seems to me this is becoming more common as time goes on. I also shucked a scope last year on my 10ML-II, but was only shooting 45grs of AA5744 and 250gr XTP. The fast focus occular siezed up and couldn't be turned.

The scopes that are failing are all designed for high powered rifles. It makes you wonder if something else may be the cause like starting the bullet off already engaged in the rifling instead of a forcing cone.

I do know it takes a special scope for an air rifle due to their recoil characteristics.

These high power rifle scopes are designed to withstand the recoil of the hardest kicking rifles there are. I am starting to think it may be how the recoil is being applied to the scope that can causes it to fail from repeated firing.

Leupold Vari X III in a 3.5 X 10 X 40 on my Savage with more than 1K Duplex loads.

May let go today but so far no trouble>

Plus if it does Leupold service has been great in the past.

Sorry Herman, but I had to read this thread based upon the Topic Title....I thought it was about an instrument that a Doctor specialized in "E. D." would use...Sorry ;D

[bubba]

LOL, I was thinking the same thing.

I read an interesting article on big game hunting optics used on the hard kicking stopping rifles professional hunters use in Africa. They prefered small variables or fixed low power Leupolds.

I had a Leupold (4.5 x 14 AO) go bad two years ago, the target failed to come in clear using the AO, sent it in and they told me the front lense had come lose. They told me that the front turn ring AO scopes were being phased out and being replaced by the side focus, as they were having lots of problems with high recoiling magnums shaking the lenses loose. I've replaced all my AO with the newer side focus AO and 30 mm tubes, they're nice, Ray

I have used a Burris 3x9 fullfield II since I bought my ML I and have had no problems.

I am a burris fan and I don't need that E.D. scope. LOL

Uh-huh...........is it the scope or the loads?? Some of you
guys introduced me to duplex loads after some of the
factory recommended loads practically kicked my teeth in.
The duplexes were faster, yet recoil was much more
tolerable to the shoulder and cheekbone than 150gr T7.
Granted, "for every action there is an opposite, and equal,
reaction". However, that can come in the form of a sledge
hammer effect, or a loaded spring effect on the shoulder,
giving the same "opposite, and equal, reaction". I prefer
the sping-loaded effect..............which one would be much
kinder to the scope??..........ANY scope?

Found what I think was a good buy on a Burris signature select 3x12 yesterday @ Natachez for 373.53.So I am going to go with that,I like the Buris and have several in fullfield and signature.
One Season starts here 10/10 and I didn't think I would get the one repaired that fast.
What I like is the blis-plex you can use the power ring to make the blis lines work from 100 to 300 yds.It took me a lot of time and shots to work this out with the fullfield so hope it works the same with the signature because it is 3x12 instead of 4x14.

Got my new scope replacement Burris scope,3x12 Blis-plex, yesterday put it on last night and off to the range this morning.Got it sighted in at 100 and 2 00 yds easy,went to 300 and shot three different loads.
Stared to shoot a five shot group with my favorite but got to the fourth shot and pulled it,so quit on the fourth shot.Shot a three shot group with 43 grs of 4759 and a three shot group with 110/323.
Just had to show off these groups to me they are awesome with a muzzleloader @3900yds.Think I am ready for opening day now.

herman,

How much drop did you have at 300 yards, and what is the 4 shot powder weight 43.5 or 47.5 ?

What types of paint do you use to to make your target?

thanks,

edge.

PS GREAT shooting

[herman]

The 4-shot was with 47.5 grs of 4759 and the group on the right was 43 grs. After hunting season I am going to try more loads with less powder,the 43 grs hit about the same place as the 47.5 gr did.So that tells me so far that the 43 gr load will do about the same as the 47.5.I have tried from 43.5 to 48 grs before and all of them shot very good groups.
I take a piece of white card board,get a roll of clear shipping tape at the dollar store cover the white side with the tape and spray with the dollar store black flat spray paint. It works on small calibers also.This wasn't my idea though it was my shooting partner that came up with the idea.
I usually use it at 300 yds because the bullet holes are hard to see even with a spotting scope on reg targets sheets.
We shoot at least once a week with many different calibers so it works very well ,all you have to do is spray over it with the spray paint and use it many times.
I all most forgot the drop with the 47.5 gr load this is my actual drop.measured drop=100yds 0,200yds 7.1 , 300yds 26.8.
If anyone wants to know how I worked the sighting out,I use the Burris Blis-plex.set the power on 6 at 200 use the first slash mark,at 300 use the second slash mark.You can work any load out this way,if you go down on power the bullet rises,if you go up on power the bullet goes down.I am zeroed dead on at 100 yds.
You can do this with a mil-dot scope also if you have one that changes with the power setting.I am not that familiar with the mil-dot but I think the ones that have the mil-dot etched in the glass don't work because they hold the same poi when changing power.Could have it backwards though.

I use Burris,,,,a very old 2X7 burris died on my ml2 last year after several years of hard use on several rifles,,,,I sent it back to burris and they no longer stocked parts for it, it was so old and the tube was bent,,,,I had noticed the control ring had gotten hard to turn,,,,,,I replaced it with a 1.75X5 burris FF2....shooting great.
