RE: reloading a 300 Ultra-Mag
I will concur with stubblejumper. I have loaded several hundred rounds for my 700 and a buddy's 700 using Ballistic Tips in front of 95.0 gr. of Reloder 25. I have gone up to 97.0 gr. with no adverse pressure signs but did experience degraded accuracy. My info came from a Rick Jamison article in Shooting Times before any other load data was available. Both rifles shoot sub m.o.a. with this load. Partitions shot approx. 1.5". Awesome and devastating results on whitetails.
Now for a question of my own. Does anyone else suffer from case neck splits after four or five loadings? I know that this load is brutal to brass, but is there anything I can short of reduced loads?
