30-30 & lee c309-150-f

[thumb bum]

the Lyman cast bullet handbook has the starting load for this bullet at 7 grains unique the max 8.7 grains unique. Cast pics has a starting load for the rcbs 150 at 10 grains in the max load a 12 grains. is there that much of a difference has anybody ran the lee boolit up the 10 or 12 grains?

I've run that same bullet with 7 to 10 gr of Unique with great accuracy. I haven't run them through a chronograph so I don't know what the velocity is. I have settled on 10 gr for all my shooting with that bullet.

Don't know about Unique but 28 grains IMR 4895 and this boolit do great in my Marlins.
