Thanks for the suggestion. I am well aware of the good loads using IMR4350. I was looking for loads for this particular rifle and twist. 150gr. bullets maybe a little light for a 1:11" twist. I already have another .300 Win. Mag and a .30-06 that likes your load suggestion but the .300 the barrel twist is different and it is a single shot. I use a load of IMR4350 and 150 NBT in the .30-06 and it will cloverleaf.
