Some folks use 2, some 3. And they say it’s the ‘best load’ frankly I don’t know if 1700 fps knows the differnce.
But let’s say that your best groups come at 1700 fps. Sixty of three or seventy of two gets you that velocity
So one would want to aim at whatever charge you needed in four to get that velocity
Now the ‘kicker’
Will it make a difference at how fast the ball is accelerated to the size of your group.
Them that shoot the tightest groups are very concerned about the powder, so I don’t know.
Loaded out of my bag my guns out shoot me, so I can’t say. If I have 2 I shoot about 10% more then 3
