I have been working up a hunting load with Remington 210 grain JSP bullets for my Model 57. Using Charlie98 load of 20.8 H110 as starting point I shot oen cartridge each at 20.8 gr, 21.0 gr, and 21.2 gr of H110 powder just to check for flat primer and ease of extraction. All was well.
Next I loaded three each at 20.6 gr, 20.8 gr, 21.0 gr, 21.2 gr of H110. I shot from bench with sand bags at 15 yards.
The results were rather discouraging using a pistol with 8 3/8" barrel at 15 yards. Either my shooting skills have degraded or my gun dislikes this load.
To confirm my shooting ability or if the one shot was a "flyer" I shot 5 rounds with 20.8 gr H110, again at 15 yards from bench with sandbags. The 2 1/8" spread confirmed the original grouping, no "flyer" involved.
Since the 21.0 grain load was much better at 1 1/4" 3-shot group.
With 21.0 grain of H110, I Shot a 5-shot group at 15 yards. Still very discouraging group.
Having read about loads with this weight of bullet, H110 powder and Model 57 with 8 3/8" barrel with loadings as high as 22.2 grains of H110, I decided to load one each of 21.4 gr, 21.6 6gr, 22.0 gr, 22.2 gr, 22.4 gr. and test them for flat primer, difficult extraction, and general accuracy at 15 yards. Something marvelous happened... Is this simply what is called an "accuracy node"? The first 4 rounds created one ragged hole. Primers were ok and extractions were good. Now we're getting somewhere.
I think next I'll load three each of 21.8 gr, 21.9 gr and 22.0 gr and see which load get the tightest group.
