IMR 4350 for 6.5x47 ???

[glider]

Looks like IMR 4350 is available in 8lbs these days .
There are mixed reviews concerning Temp. and velocities .
Any feed back from guys who have experince with this powder is appreciated .
Im shooting 142 smk,s over varget and H4350 , H4350 is hard to find in 8lbers
Started loading Varget with good results
Lapua brass BR primers and 450 mag primers .

Can't comment on the imr 4350, but switching from cci br4 primers to fed 205m primers really tightens up my groups with varget.

Just did a temp test on 4350 this weekend as a cold front dropped us to 38*f in south texas.

Over a span of 40 degrees i got a ratio of .77fps/deg with 4350 in a 308 win. measured with magnetospeed on the same batch of bullets.

However i still use .4 in my software, over small swings that big ratio hurts more than it helps.
