How much H335 behind 123 gr SST? - natebonebusta - 02-22-2023
I was able to produce 2464fps at the muzzle with my 1500 howa mini 18.5 barrel with a load of 27.9gr of H335 and OAL of 2.250. I did run my silencerco harvester. The 123 sst shot really well in front of the h335. I was hoping benchmark would be as tight, but it produced lower velocity, and a .25 larger CTC group.

Without looking in the workshop for the records, Im sure it was 2.245, which was the recommended OAL for that bullet.
