Destry, if these load are light even for moths, how about houseflies ? But on a more serious note, I'm just looking for a factory load (since I don't reload) that won't tear up my Smith's, (ahem)Parkers, and Syracuse LeFevers. Since I looked on the FAQ page, I found Federal's Gold Medal 7/8 oz, 1200 fps, 5000psi. load. What about this shell? Will it bring down the butterflies, and maybe a dove or two? Season opens on Sep. 1 here in Tx.
