What powder for '03-A3 w/ Rem 150 Corelokts?

[1894cfan]

Just Picked a Rem/Springfield '03-A3, and was wondering what the "best" powder would be using 150gr Corelokt bullets. I know that each firearm is a law unto itself, but what's the best all around powder for 150gr bullets. TIA

I use IMR 4895 and 4064.

I use IMR 4895 in all my military surplus guns in the bolt actions and in the semi auto's this way the reloaded rounds can be used in either gun.  The IMR 4895 gun powder is the correct burn rate for the military semi auto's.  Using the wrong burn rate in a semi auto can throw off the cycle timing.  I'm playing it safe and using it all my military reloads so i can have one reload for both rifles so there is no mix up.  Having two seperate rounds for one caliber can get mixed up.

4895 and 4064 are both fine starting places.Also may want to try one of the 4350's
