The V block method is the best, but you need a surface table and a set of v blocks with the correct angle for the number of grooves. Seven grooves is common, but so is five. that's at least two sets of blocks,

So as a general rule of thumb if the bullet is too small would this cause tumbling?
I've had a few rimfire tumblers and due to the inconsistencies in the manufacture of the bullets this would tie in to me.

It could, but other factors could cause tumbling. Too slow a twist or too low a velocity for the length of the bullet: these are the usual culprits.

If you had an AR15 then he'd really make you have it!

Remember legally you can only get pretendy ARs in this country, not real ARs.
