hi guys
so the other day i was thinking there must be away of making better use of mauser/tikka length rifles.

i was thinking maybe if you had an 308 or 7mm 08 rifle you could run a 30.06 or 280 reamer in so much then just slowly neck back 30.06 brass until you could close the bolt.
i then worked out few issues knowing neck length, variable chambers on each rifle, and because of the different taper between 30.06 and 308 you would end up with a step in the chamber.

then i wondered if you could use a 308 chamber reamer and just over run it in a bit. its at this time i clicked that there is the x57 cartridges that full nicely in the middle but this doesn't help you if you already have a rifle chambered in 308 or 7mm-08.

my question is could you run a 308 win reamer further into a chamber and use a X57 head space gauge to set depth? might seem like a hassle but im guessing 100fps plus gain

brass would be simple use 7x57 brass or trim back 06 length brass and make a neck using a f/l die in either 308 or 7mm-08 not screwed fully down.
i played around with using 270win brass trimmed and ran through a 308 die.
left to right
308win with 168gr amax, 270 trimmed necked to 308 with 168gr amax start of boat tail inline with bottom of neck and 270 next to it.

made dummy round in tikka mag and mauser
