I had to do some looking for my notes, I started do reno's on my reloading load last winter, and don't have it done yet.

These notes are based on my ultralight(which is picky on loads) only, I have never tried any of these loads in my other 270 wby's, so I don't know how they did in those rifles.

The norma website and info I got, says they load the ammo to a OAL of 3.228", but my actual measurement of factory loads are 3.20". The factory 130 gr spire point load, shoots on average just under 3/4 moa, at a chrony speed of 3355 fps.

With 68 gr of IMR 4530( max load), 130gr spire points at 3.20", I get 3/4 MOA and a chrony speed of 3347fps. Loads from 66gr -68gr was accurate.

With 74gr of MRP,130 gr spire points at 3.20", I get just under 3/4 MOA, at a chrony speed of 3362 fps. Loads from 73gr -74.5gr(norma's max) was accurate

Just in case someone else is interested in a few other factory OAL's for the 270 WBY

factory 130 gr TSX load OAL- 3.250"

factory 150 gr spire point load OAL- 3.210"
