How much is too Much

I just tried some reloads for my 6.5 Rem Mag. The brass was brand new. I loaded 47.0 grains of IMR4320 behind a Berger 130 gr. VLD bullet, which was seated to a depth of 3.110". Yes, I had to load as a single shot, as I'm shooting a Remington 673. I measured the fired cases, and I am getting .005" stretch in length, going from 3.164" to 3.169", and .004" stretch above the belt, going from .506" to .510". Is that excessive stretch or not? Grouping was 1.25" on 3 rounds, and the 4th flew out to 1.75", or it may have been me too, because I was in kind of a hurry, and the gun was stone cold out of the cabinet. Thanks.
