I was right, it was Win 760...
Please use the data below as a simple reference. Each rifle is different.
54.5 grns Win 760
Fed 210 M (match)
Winchester "nickel" brass
Case OAL 2.540"
COAL 3.320" Do not seat the "X" bullet any closer to the lands than .050" off. I would consider seating even deeper depending on the rifle - so my COAL is just a reference. You need to measure your rifle with the bullets you are going to load. I have a Stoney Point OAL gage in .270 if you need to borrow one (great excuse to meet a fellow Killer).
I was getting an average 5 shot velocity of 2920 from my 22" barrel.
I also found H4350 to be very accurate but could not get the velocity I was looking for in my short barrel. You may try H414 as well, it is a good powder for the .270 when shooting in a 22" tube.
Sorry it took so long but I could not find my .270 folder. I was loading the 300 WSM and the .260 Rem. last time I was on the bench. I just realized I need to get reorganized! :
