I’m new here (first post) as an official member, but I’ve spent many hours on the forum and read many of the threads here. I will admit that I am fascinated by the discussions of long-range hunting and the specialized equipment/modern cartridges used in the pursuit of making precision shots on game at long range. And so, I apologize in advance for the mundane nature of my question...it’s about an old gun, an even older cartridge, and shots at short to moderate ranges.

Gun: Browning A-bolt (original A-bolt manufactured in 1988).
Caliber: .270 Winchester
Use: Whitetail hunting from tree stands in NC and SC with shots ranging anywhere from 10 yards to a max of 300-400 yards.

I’ve been hunting with this same rifle for 25+ years. It has above average accuracy for a factory gun. It’s taken a bunch of deer. So, I’m perfectly content with the platform and the cartridge for my needs, but I’m ready for some new optics. My current scope (Leupold Vari-X III) has issues with maintaining zero, and after finding this forum (and the drop tests), I think I know why. For my new scope, I’ve decided on a Trijicon Credo 3-9 X 40.

My question is...what is the best mounting system for the new scope? I’ve read a lot on this forum about picatinny rails, high dollar bases/rings, lapping rings, bedding bases/rails, etc. Is any of that needed or beneficial for my setup, or would it be overkill for my intended usage?

Would a one-piece picatinny rail obstruct the ejection port on my A-bolt and cause issues? I know that Trijicon makes a two-piece picatinny rail specifically for the A-bolt. Would the picatinny rail (one or two piece) provide any advantages to me?

Should I just stick with the old style, traditional looking, standard rings and bases since it’s an older rifle?

I know I won’t be shooting at extreme long range, or backpacking over rugged terrain, etc. but I do want a rugged, quality setup that will consistently maintain zero. Suggestions?

Thank you!

I've seen a lot of negative feedback on this forum in regard to Talley rings cracking/failing, so I'm somewhat leery of trying them.

If you think your current ring and base combo is good, I would suggest starting with that.

If you want to upgrade, I would look at any options that Warne offers for your rifle.

I have the Talley scope mounts on 4 rifles ranging from 6.5cm to 300 win mag. The 300 has been my main hunting rifle for several years. No issues or failures. I do bed the bases with Devcon when I install them. Lots of good options out there. Just stay away from the redfield/leupold style with the opposing screws on the rear mount. They are a weak link. Just my 2cents
