KW- Lol - so true.

JB and others, good info.

In an IDEAL world, it seems if one has a #1 contour side by side a #5 contour, same length, all specs, load, rifle/bedding, etc. and put them both in a vice, then both rifles would theoretically shoot a say 10-shot group in more/less the same size?

As to 10shot strings, perhaps if I had a 221-223 of modest capacity not a big deal, but many rifles will get VERY hot after 10 rounds, to me accelerating throat/bbl wear, i.e. a 220 Swift.

So accuracy aside, accelerated bore wear is enough for me to shoot 3 shots vs 5, or 5 vs 10.
