I have an HS Precision 375 RUM. It shoots well. I have in IOR 2.5-10 and a Kahles Helia C 1.5-6, both on Talley dettachable mounts. The IOR performs well, but I seem to be getting some flyers with the Kahles. Like an inch group at 100 yards, with one or two several inches away. I've had scopes fail, but that usually involves cheap glass and extreme inconsistancy, with shifting zero. This just seems to be giving me funky groups. Anyone out there have any trouble with these? I have to think the issue may not be the scope , but something I can't see. The Talleys are tight, but should I consider remounting? I know it isn't the bases, as the other scope works fine. I'm leaving for Africa in a month, and need to resolve this, either with this scope or another.

I have the same Kahles scope on my 375. I have had good results, no flyers. I would consider remounting. If you have another rifle that you know shoots consistent groups try putting the Kahles on it and see if the flyers continue.

Seen 2 Kahles go bad on a 300 RUM, a Nikon conquest has been holding up for Chris for about 2 years since.

I agree with KC, if you can put on a different scope and it doesn't give you the funk, than you've got your culprit.

Good Luck--Don
