Hello all,
I am fairly new to USPSA, and reloading on a Dillon 650. I do have the knowledge of reloading down. Familiar with the process, just new to the Dillon progressives. I'm having issues making Major Power with my reloads. Currently I am using mix brass, deprimed and wet tumbled, lubricated and loaded in the case feeder.
Using CCI Large Pistol Primers
Rainier 230 Gr Copper Plated Bullets (weighed sample of 10, 228.95 was the average)
Universal powder, 5.5 grains.
COAL is consistent at 1.25"
Crimp is consistent at .471"
I have the Arredondo micrometer powder bar installed, and the powder throws were verified prior to seating the bullet.
My firearm is a SW1911, with a 5" barrel.
Attached is a spreadsheet I ran, with a sample test of 10 of my loads. Minus MV data, I lost the sheet.
Ran across a Chrono, with the assistance of a PRO, was 10 feet away from chrono. Loads are erratic and not making the minimum MV of 718 FPS. Anywhere from 690's to as high as 774. I would say the average was 705.
The loads are accurate however.
No evidence of copper jacket separating in barrel/chamber. Rifling bright and visible, after 300 rounds (USPSA local match).
I'm having a tough time finding published load date for the Rainier 230's for use with Universal. It is suggested to load to the LRN spec, of which I am very close to reaching, believe that is 5.6.
Would seating the bullets deeper, say to COAL 1.23" give me more velocity?
Any ideas/suggestions are welcome. Appreciate the help!
