Recommendations for mounting a Credo 3-9 X 40

[Skydog]

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!

Talley one piece ring mounts are strong and lightweight. My go to for hunting rifles

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.

As you should be. Pic rail bonded to the action and quality rings would be my suggestion.

 

[keystone112]

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

What specific rings would you recommend?

Would a one-piece pic rail obstruct the ejection port and cause issues?

What are your thoughts on this two-piece pic rail made by Trijicon specifically for the A-bolt:

[WeiserBucks]

One piece pic rail and NF, Badger or Warne Mtn Tech rings is my recommendation.

 

[keystone112]

The trijicon two piece base looks good to me. Maybe a bit taller than I prefer.

 

[Schutzprecision]

A 1 piece pic rail and rings will partially cover the ejection port. Ejection shouldn’t be an issue. They do mount the scope a little high on a standard stock. This may or may not be an issue for you. Everyone has different preferences. Nightforce pic rails are quality and have always worked good for me. The 2 piece picitanny bases work good also

I’ve use both Leupolds and Talleys on many Browning A bolts without issue (or testing) but, I’ve since started swapping to Leupold picatinny rails for my A Bolts (and some others) and Warne Mountain Techs. You won’t have ejection issues with a pic rail on an A Bolt, and you’ll have more flexibility for eye relief with a full rail.

Your scope choice is a solid one.

Have you had any issues with adjusting to the scope being mounted higher due to swapping to the picatinny rail?

No. Low Mountain Techs are good for me on a rail.

I'm moving all my rifles over to rail systems, though I don't like the extra height I like being able to very easily swap scopes between rifles and I feel like it's a very solid mount.

Having said that, I had to adjust my 3-9x40 Credo down 4 clicks at the last range trip, it moved after coming back from an Elk hunt. Come to think of it I hit the Elk a little higher than expected as well. Who knows if it's the scope or other details but I wasn't happy about selling a Leupold that never moved to replace with the Credo only to have it move.

 

[Schutzprecision]

Not to detail the thread but Which credo do you have? Eying a 2-10x 36 as a compact light weight ffp scope that dials elevation and has a good reputation for holding zero.

Are you asking me? Mine is a SFP 3-9x40 I bought here on RS. It's got the MOA Precision Hunter reticle. If that was directed at somebody else I apologize.

It’s hard to beat Warne bases and Mountaintech rings. There’s not really a need for a rail in your setup.

Also, I’ve got Talley UL one piece mounts on my Barrett Fieldcraft 270 with a Trijicon Accupoint 3-9x40. I’m north of 2000 rounds through it with no issues. I had Talley mounts on my Rem 700 308 for 10,000+ rounds with zero issues as well.

I just mounted a credo 3-9 on an x-bolt. I used the warne two piece bases and mountain tech low rings. 5.5oz all in for the rings and bases and is rock solid. A little spendy but it gives me confidence.
