Re: Reloading info for 300 Ulta Mag
Rot,
Many of us shoot them. If you search on google for something like "300 ultra load data snipershide" you will find a lot. That said, here is what mine like:
Rem 700 LSS 26" RWS Brake, bedded, trigger job. Nothing fancy.
Rem Brass trimmed to 2.845, neck turned .014
Win LRM Primers (Fed 215s are my fav)
Berger 210 VLD
Max length for mag (VLDS will never touch the Lands and fit in mag)
H1000 90.5gr is what mine likes
Hope this helps. Save time and money and run a Creighton Audit test on your ammo.
