barrels and grooves

[pakm]

I slugged the barrel in my Armi sports spencer and it measures .4515 with six lands and grooves. Lee tumble lube bullets work just fine. (250 gr. so far.) more on loads later.

I got my Taylors spencers in today. they have 6 lands and groves, they are all blue and beautiiful, and the action of the one I took out of the box is very smooth.
