This works good for me. Rem. Sendero 26".
160 gr. Partition
91 gr. Reloader 25
Fed 215m primer
oal 3.650
best group .231

Matt. What was your average group size with that load??? thanks..GREG

Matt, what is the velocity? are you using a chrony?

As for a average I don't have one,I had a friend help me with the load after I had enough and was ready to give up.I tryed 150 gr. swift and 140 gr. Noslers Bt. However after talking to Nosler they pretty much told me that the Nosler Bt I shouldn't use. I guess it was because of the speed and the jacket maybe to thin. I did use a chrony and with the 160 Gr. part. I was getting 3405 fps. This is below the factory ammo fps specs,but I don't care if it's a little slower,It shoots great for me.
