I have been looking for a 338 sized mag for my 300wm stock project due to OAL being longer than 300wm mags
AI and Sporting Services was my first port of call but order times of 2m and then only CIP length mags on offer made it a worse case scenario (not to mention no reply to email, a surly first conversation with a chap who didn't want to speak, cut me off and had to call back..)
Stumbled across this place. riflemags.co.uk
Seem to have stock galore in the UK
Very nice chap calls me back same day, walks me through my options, takes payment over the phone, ships same day, arrives two days later!
Great service and a pleasure to deal with.
All metal phosphate finish mag from Accurate Mag in the US, came in a choice of three lengths
my long 208gr load fits like a glove with a mm or two to spare
now for the tricky part!
