I have tried the Winchester, but admit I did not give them a fair test. I loaded some 150s in front of my usual 4064 load in my '06; got a horrible group. Three shots, six inches apart horizontally, 2" vertically. Duh?

I later read that they have a harder jacket than the usual bullet, and pressures could be higher than one's "pet load". This might account for my problem. As I say, no fair test.

I have read, here and in the gun mags, that all three bullets are known to work well...

Regardless, start low and work up; I probably should have--and will, next time around.

FWIW, Art
