375 Rugers won't feed well.....

That was with flat meplat bullets that supposedly don't feed well to begin with.
With a 20" barrel I get:
2720 fps with a 300gr Nosler Accubond with RL17
2755fps with 260 NAB and 270 TSX and H4350 (RL17 could pump that up more if I wanted but I am happy with those loads I worked up before RL17 was available)
And although 300gr bullets in the H&H have long been able to kill everything everywhere, I will try the 350gr Woodleighs when they arrive but I expect velocities will be about the same or a little more than the H&H using the same bullets.
In fact the guy at Gun Blasts did a test with 23" barrel 375 RUger and 25" CZ550 375 H&H and the 350gr Woodleigh and found that the RUger got higher velocities with all powders tested.

I don't see much point in the 350gr TSX. I actually think it won't work as well as the 300grTSX, probably penetrate less. But that is just theory as I haven't tried them and none of the African hunters on AR seem to be interested in them.
