Just curious but what have you guys found to be the max scope weight that a given spring gun can tolerate?

Reason I ask it that a while back, I had a big Sightron 10-50x60 that I tried on a HW77 and it wouldn't shoot accurately with that scope on top. Pull it off and put the Bushnell 8-32 back on and it's a tack driver.

Sightron lists the weight at 29 ounces plus whatever the sidewheel weighed in at. It was a Jon Harris wheel, so I'm guessing maybe 6 ounces, perhaps 8?

But the Leupold Comps weigh in at just over 20 ounces sans sidewheel and seem to do okay with respect to balance. Many use these. Bushnell 4200 8-32x40 are 22 oz and no sidewheel needed and is used by many more.

I did not try the Sightron scope on any other piston rifle. I've heard some have used the large Nikko scopes with success and those were pretty heavy IIRC.

Could this just have been a situation with my particular rifle?

Could it be more of an issue with balance than weight?

Has anyone found HW rifles to be more sensitive with regard to weight and balance than TX guns? Vice versa?

Paul,

Do you think it might just be that the Sightron had issues with the recoil of a springer? I know that several successful spring gun shooters in the past have done really well with a Nikko on piston guns. Those are pretty heavy scopes too. Maybe the scope just has something inside that moves around under the recoil of that springer?

with good results. The Hawke scope with mounts,lens covers, sidewheel, and level weighs 41.8 oz.

I am also using a Leapers 8-32X56,which is a heavy scope, on an HW 98 with no problems.

Johnathan Reyes won the 2010 Nats with a 10-50 Nikko on a TX 200 and the fellow who won the Springer Class at the Worlds in Italy had a pretty big scope on his Pro Sport.

I know Johnathan weighted his stock and the fellow at the worlds used weights on his gun also. Might be something I need to look into for the Falcon T50 on the Tx 200HC.

My conversations with the Sightron people led me to believe that they do not really guarantee the performance of their large scopes on springers.

I am currently using my Horusvision 4-16X50 that weighs around 28 oz. on the WFTF D54. With the ASLI and the mounts, you're looking at around 35 oz total.

If you can affix a good pistol laser to your rifle, test to see if after one, two and three shots, the scope and laser are still looking at the same spot.

"Could it be more of an issue with balance than weight?"

From my limited testing and experience over the last year, I believe that balance in very important in a piston gun. If you have a heavy scope, you need some firmly mounted weight below the receiver. If I can balance it so that the CG of the rifle is along the piston axis, my hold sensitivity is reduced greatly.

The scope was very good and repeatable, before and after the installation on the HW. I put it on one of Rod's Dominator's and it was good to go.

Was it right below the scope on the underside of the stock? Hollowed out the stock and glued in weights?

Internal or external weight?

Paul, I'm sure others have methods of adding weight but here's what I've done with my spring guns. I have added lead weight to the butt as well as into the bottom of the stock on one of my custom stocks and have incorporated weight into the riser on my TX200 SR.
