Got my rifle back from the gunsmith last week and I have fireformed and shot some loads. The initial results are excellent.
With fireformed Fed 30-06 brass, I just shot some molied 165gr Hornady SST bullets into a ragged hole at 100yds. The powder was H4831SC (64gr) and CCI BR2 primers. The throat has been cut so that my bullets just engrave the rifling when chambered (still feed from the magazine).
Will chronograph soon but should be in the WSM/win mag range. Rifle has a 26" barrel. Recoil is stiff and a muzzle brake
will be added soon. Will try some long range shooting as time allows.
For someone thinking about the WSM but because of budget can't do it, I would recommend the 30 Gibbs as an alternative. Any 30-06 rifle can be rechambered for this round and it should give the same performance for the cost of rechambering (about $75 to 100).
Get a neck sizer or maybe a Lee Collet 300 Win mag die and you are set. The reg. 30-06 or 308 bullet seater will work. When the brass gets too big to fit, throw it away. After three full loads, the brass looks great. A tight chamber and sharp shoulder are keeping the brass from stretching or bulging.
My new "skinny long" magnum...
