.45 ACP Loads for CBI Powder.
Just got back from the local indoor range with some good results for the CBI powder in .45ACP. These results were from using my Glock 21 with stock recoil springs and a Lone Wolf .45ACP barrel.
The gun cycled properly with all of these loads.
Bullet was a Better Bullets 200grn LRN. S&B LPP. I would expect similar results using a coated 200grn bullet.
CBI Powder charge Average Velocity (fps)
5.6 grns 806
5.8 grns 824
6.0 grns 851
6.2 grns 873
6.4 grns 890
In a couple of sets I noticed some rather large deviation from low to high. In the 5.6 grn results I discarded the high and recalculated the average for the above result. It is pretty obvious this powder does not meter very consistently in my Dillon powder system. Perhaps some type of vibrating device attached to the powder dump might help. A .2 grain increase showed to result in an approximately 20fps increase in velocity.
My long standing “go to” load for this bullet in .45 has been 4.0grn of TiteWad. That load showed an average of 856fps.
Overall I’m pretty impressed with this powder for .45. I didn’t think it was a bit smokey and was a pleasure to shoot even at 6.4 grns.
I’m still trying to find a brand name that comes pretty close to this load data to use as a guide. Any thoughts on this would be appreciated.
