Need Help With A 300 wsm Magazine Question

[GRobertC]

Hello;

I'm having a custom 300 wsm built on a Tikka T3 action in Roedale RCS II long action chassis. The long action Roedale chassis uses Voere LBW magazines and the 300 wsm magazine inside dimension is 3.122 and I'm not sure that will be long enough to accept the 300 wsm loaded with Berger 210 VLD'S.

I'm wondering if anyone knows of another cartridge with a similar diameter to the 300 wsm that is longer so I can see if Voere makes a mag for that caliber. I was going to use a 300 win mag magazine, expecting to have to possibly bend the tabs a bit to feed the fatter case but Voere says the 300 win mag magazine's shoulder stop is the same as the 300 wsm. I don't understand how that can be when a 300 wsm is 2.86 long and 300 win mag is 3.34.

I suppose the 3.122 length of the Voere mag might be long enough, but I would rather have a little breathing room.

Thanks
