I took 50 shots in 10 rounds of 5 shots each today.
No warmup shots
28.5" asymmetric sling (parcord with leather pouch)
Byzantine style
30x36" target size with 12" bullseye
Results: 32/50 hits
I didn't tally up bullseyes versus normal hits.
64% Accuracy
Looking at the effects of a warmup... 1st 25 shots: 16/25 = 64%
second set of shots: 16/25 = 64%
No change across 50 shots
Maybe next time I'll try 100 if I have time.
