When I ran out of Unique, I went from using approx 5.8 grns of Unique to 5.3 grains of HP38. The HP38 doesn't fill the case as much as the Unique does. I like to keep the COL at 1.265" to keep the accuracy in tact, however I wonder if I'm leaving too much empty space in the case? Is it better to keep the empty space to a minimum by seating the bullet deeper, or better to keep the COL longer and suffer a larger void in the case?
Thanks for any input ya'll have.
My suggestion is that if you're changing powders, work up a load on HP38 seperately. There is no direct correlation between keeping the COL the same and how it affects accuracy with a different powder. COL will certainly affect how a particular bullet feeds/functions in your gun though. Work up a new load and see what happens on paper; you might just like HP38 better. Pay attention to MIN OAL's and you'll be fine; seating a bullet deeper than MIN is going to greatly impact the data in the manuals and quite possibly your gun/hands/life.
In general, greater load density does equate to an increase in accuracy/consistency. Properly working up a load after any change in components is what will greatly increase accuracy/consistency AND safety!
