Anyone used these out of a .22-250?

60 grain Partition

The powders I have to choose from are 4064, AA2520, and H380.

Looking for a tack driver going between 3200-3400.

Any advice welcome thanks.

What barrel twist do you have?
I had a M700 VLS in 22-250 with a 14t. I shot 60 gr PT just fine but the bullet profile changed and the new style OT wouldn't stabilize.
I went to the 64 gr BSB bullet and they shot well.

.224 64 gr BSB

.224 cal 64 gr Bonded Solid Base MV 3372 fps shot into water jugs at 30 yds, recovered in the 5th jug. The recovered weight was 50.2 grs (72%) and expanded to .481". JD338

I used RL15 in a few of my old ones. Pretty similar to 2520 and 4064.
