Which AI pattern SA magazines feed the longest rounds?

[Onewolf42]

I'm planning to install AI pattern bottom metal on my 284 Win SA (Manners T5 stock). Which AI pattern SA magazines will reliably feed the longest rounds?

Thanks.

MDT metal mags w/o binder plate: 2.960"
ARC mags: 2.940"
Accurate mags w/o binder plate: 2.950"

They're all pretty close to the same. Make sure your action has a feed ramp that can handle stuff seated that long.

Thanks for the reply/information. It seems that the Ruger RPR magazines are made by (same as) Accurate Magazines. Do you know if the Ruger version of the magazine has the binder plate or not? I assume (unfortunately) that the Ruger version has the binder plate?

I'm not sure. I don't have any personal experience with the RPR. I always thought it came with a Magpul AICS, which can only go to 2.86"
