I was able to get out and do a little chrono work yesterday...between the rains <sigh>

I got the idea of using this general data from posts by @Outpost75 and @Lost River Not their data but my extrapolation from various posts.

I wanted some practice ammo that would service potentially as a SD round and would play nicely with my HKS speedloaders for my LCR 327. I have several boxes of 85 gr XTPs in my component stock. So why not?

IIRC the suggested threshold for expansion was mentioned to be 850 fps.

All loads shoot better than I do...

.32 H&R mag 85 gr XTP
W 231 3.4 grs Avg FPS = 797
SASPP Ruger LCR Prochrono ORSA

.32 H&R mag 85 gr XTP
W 231 3.6 grs
879-861-867-868-897 : Avg FPS = 874
SASPP Ruger LCR Prochrono ORSA

.32 H&R mag 85 gr XTP
Bullseye 3.0 gr Avg FPS = 818
SASPP Ruger LCR Prochrono ORSA

.32 H&R mag 85 gr XTP
Bullseye 3.4 grs
857-851-863-869-881 Avg FPS = 864

I don't even own a .32 wheelgun and I keep checking this thread.

Comparison between my gold standard MBC 98gr / Win. 231 at 3.0gr and the new Slippery 78gr / Win. 231 at 3.0gr

You can clearly see a difference in both accuracy and precision. While the scores are close-ish, the targets don't lie. The lighter bullets do impact lower, so my POA was the 12 o'clock position of the 10 ring with those. Also of note, the SB78gr being a short bullet and loaded long, can lead to a slight tilt in the case. This produced drag on the breach face. In turn (haha) it led to a less predictable pull, and sighting errors. Where the shorter OAL, MBC WC allow the cartridge base to move more freely when the trigger is worked. Today I shot 75 of the Slippery bullets, and could feel a slight difference in recoil among several rounds. With such a small charge weight and less cartridge case filled with bullet, I believe the powder may have been affected by position. The heavier recoiling rounds did appear to impact higher.

At 25 yards, the MBC 98gr produced 118-2x / 120 and the SB 78gr produced 114-2x / 120. However... with the MBC, the 2 out at the 1 o'clock where fired as the SBR in the next bay let loose. To say it affected several shots would be a fair statement. All the SB78gr were fired when I had the range to myself.


The SB 78gr definitely loads easier in both the press and the gun. They work excellent in the HKs 32-j, and are a fantastic light recoil option.

I'll be ordering the MBC 98gr again.

I also shot the HiTS ASST that I will post up in the what did you shoot today thread.
