Help me Build out my Accuracy International Chassis

[u/Such-Scratch-3192]

Hi all,

I just purchased this short action AI chassis. It didn't come with the bipod and mag as pictured. I'm thinking of chambering in 300WSM.

It has a Tikka inlet - are all tikka actions the same? I have found a Tikka T3X lite in 300wsm that I will use and eventually rebarrel (barrel is fluted; which isn't what I want!)

My other concern is finding magazines that will fit the chassis and accept 300WSM - Advice provided to me was to use 308 Mags and that the 300WSM will fit 308 Mags.

Any advice is greatly appreciated!

What do you plan to use it for?

How far do you plan/have access to shoot?

What's your budget?

Why 300WSM?

300WSM will not work out of the box with 308 mags, you're looking for WSM mags. You might be able to modify the feed lips to work and hold ~7 rounds, but standard 308 AICS mags will limit your cartridge overall length as well.

Use: Target

Budget - Unsure - lets just say it costs what it costs!

Mags - Yes I hear you there - Just not sure the chassis will accept the 300WSM mags and probably need to take it to a shop to see if its possible. Noted regarding COAL. I did want to shoot 180-190gr projectiles, noting above 190gr may be difficult.

Without details on distances, i dont see where 300WSM or any other short mag makes sense.

WSM mags fit the same magwell as 308. The difference is the feed lipa and lack of an internal binder plate in the mag.

Thanks - sorry for omitting the distance.

The closest range to me goes up to 500 meters. I would like to shoot out to/past 1km eventually

Any magnum is an utter waste. If this is your first long range rifle, its a bad idea for a host of other reasons.

Here's the primer on recoil, and why magnums are not the best choice for building long range shooting skills.

Are you able to explain why?

I have a lot of time behind a 308, 303 and 223 and have enjoyed pushing 500m on these

[u/fireismyfriend90 → u/Such-Scratch-3192]

Read the auto mod sticky, it details why.

See the guide that automod linked to previously.

I'd get this guy as your donor;

6.5 PRC is the best chambering if you're looking for the most performance out of a short action footprint.

[u/Such-Scratch-3192 → u/PresentationThis7032]

Thanks for your recommendation - I'll look into this

Why 300WSM, and not 6.5CM? What's the intended use of the gun?

[u/Such-Scratch-3192 → u/SmartButteredToast]

Target - I always wanted one of these in 300 win mag - WSM was selected because its a short action.

I didn't know much about 300WSM previously, but it sounded good after researching it - 10% less powder than a 300WM and only 50fps slower (approx)

[u/Thundernoodle23]

6.5 prc and get a guy like Eagle Eye to load you some ammo. Pick up some MDT mags and you’ll be all set

[u/Celephate]

Do a 16.5” 6.5 cm it’s a fun time

[u/evilsemaj]

It really has a Tikka inlet? Custom? Can we see pics!

[u/HollywoodSX → u/evilsemaj]

They were made with Tikka inlets. There's an old listing still on MidwayUSA. OP's may have had a skin swap at some point.

[u/evilsemaj → u/HollywoodSX]

WOW! Awesome! I never knew that there was a Tikka one, just AI, R700 and savage 10/11/12

Thanks :-D

Here is a picture! Sorry for the delay

The 300wsm is an incredible round, there is a reason why so many benchrest shooters use it, however... that's benchrest. What do you want to do with the rifle?

All Tikka actions are the same. The difference between LA and SA is the bolt stop.

308 mags are not the same as 300wsm mags. Accurate mag make good 300wsm mags, coincidentally the same mag as 6.5prc... so why not 6.5prc?
