I took them with me to Nebraska and after getting a click, click at the first rooster I got up, I tried several more and none fired, so I left them on a fence post at a public hunting area in the southeast corner of Nebraska.
The lead balls for "single-ball" loads put out by our North American ammunition companies were 1 1/8 ounce in 10-gauge, 1 ounce in 12-gauge, 7/8 ounce in 16-gauge, 5/8 ounce in 20-gauge and 1/2 ounce in 28-gauge. The balls were small enough to go through chokes, the gas sealing being done by the wads.
The ball diameters were --
10-gauge -- .710"
12-gauge -- .645"
16-gauge -- .610"
20-gauge -- .545"
28-gauge -- .510"

Ah , see for the 10 gauge I was looking at .775 round balls which are 700grs pretty close to 1 5/8 which I think its 710gr . That would be a tight ball for a smoothbore though .
This was the chart I was looking at .
Pure Lead Ball Weight
.662 = 437 grains
.678 = 469 grains
.680 = 473 grains
.690 = 495 grains
.715 = 550 grains
.730 = 586 grains
.735 = 598 grains
.760 = 661 grains
.775 = 700 grains
.835 = 875 grains
.919 = 1167 grains
1.052 = 1750 grains
The .760 661grs comes out to 1.5 oz with a 0.010 patch would be .77 which would fit a 10 ga . But from what ive read on roundballs, guns can be picky about roundball diameter and patch thickness .
A different question , is there any benefit to using a slit vs unslit wad ?
Though I want to try the fiber wads to get a feel of how it was done 100 years ago .
