Seems like I'm having some difficulty in making Major with my .45 XD, 4".
Loading Clays under a Precision Delta 230gr FMJ. I'm loading to COL of 1.25
Went to the range with a friends chrono yesterday and got these numbers (these are average of high 3 of 10).
3.6 gr. 642 fps for PF of 147.8
3.8 gr 671 fps for PF of 154.5
4.0 gr 715 fps for PF of 164.5
I've got a number of options I think. One is changing powder, but I really like using Clays since it's also my shotgun powder so that simplifies my life.
It was suggested to me that shortening the COL to 1.20 might increase velocity.
Does anyone have any knowledge of just how much of an increase I might get with that adjustment? Any other pros or cons of shortening things up a bit?
Another suggestion was loading up 4.1 grains and 4.2 grains of Clays, but I'm a bit leery of that since the Hogdon manual recommends 4.0 as the max. However I've got no flattened primers or other signs of overpressure.
Any thoughts will be appreciated.
Thanks--Steve
