Good Day at the Range

Not that there is such a things as a bad day at the range...

Anyway, I often go the range with a specific test in mind, often load development.

For load development, I load the powder charge I think should be about right, and then load an increment (or 2) more and less powder, and shoot for groups.

Sometimes the test is inconclusive. A good test shows a significant change in several different guns. Like today.

In this case I was testing 38 Spl and 357 Mag with 148 lead wadcutters with Viht N320. The book suggested 3.2 for the 38 and 3.5 for the 357. My experience has been that my guns do better with higher velocity, so I loaded the book load and then each with 2 more increments.

38Spl 3.2, 3.4, 3,6

357 3.5, 3.8, 4,1

I shot each load through 4 different revolvers in both calibers ( 8 guns). In each case, the book (mild load) was the worst group and the hottest group was the best, and the middle load was in between.


But now I have to go back to the range with some other guns and test the hot loads in them, plus another load, one step hotter.

In this picture, you can see a pair of 38 Revolvers, with the book load on the left and the hot load on the right.

The moral of the story, it try some different loads. It makes a big difference.

you took 8 revolvers to the range? That is a good day.

I have quite a few revolvers. They are like grapes....

I have about a dozen of each maker, in each caliber.

The 22s are not as fussy about ammo as their semi-auto cousins. The 32s make a nice bang but never hurt the hand. (My hand is bruised today from shooting heavy 158s (800 fps) in a bunch of snubbies.

The most reliable has been Ruger. The least reliable is Rossi, followed by Taurus.

In general, the most accurate are Colt, but I have a real tack-driving GP100 and S &W M67 and M66.

It is annoying that there is no commonality that the sight adjustment is the same on all makes. It would be nice if clock-wise was always right (or at least put a little arrow and a R on the sight).
 
Found a good 38Spl and 357 load. But now I have to test 0.2 gr hotter, to see if that is even better.

With a new powder I usually shoot a much bigger spread 0 say 3.0 to 5.0 gr and see that the groups are best at a certain load and fall off on both sides.

This test was too narrow, so I don't know if groups will improve as I get hotter.

Back in the day I was a good shot. I could shoot NRA slow fire in the 90s and timed fire was about 50% 100s.
