Do it the Australian way ... .410 with 2 1/2 no. 9 shot ... less noise, no recoil, blows the head clean off at short range. That's why they call them a 'snake gun'. Use a double barrel, so if you can only see the tail or body you have a second barrel for when the head pops up. The .410 is the standard for farms. PS Nowadays we're only allowed to shoot them if we are threatened!actually my modified 870 with an extended magazine and short bbl. is my snake killer of choice. first 3 are 8 1/2 shot next 2 are 00 and last is a slug. this snake was shot with 00 cause that and slugs are whats in it as its kept closer to river (gators) than the house where the streetsweeper is.
Our snakes rate as some of the most venomous in the world, and some of the angriest in summer, too! They will come after you, at times. Look up the Eastern Brown, Taipan, and Red Bellied Black. Biggest Taipan I've seen here came in at 2.3m, and was chewed up from one end to the other by one of our dogs (which was fine afterwards, we thought he was definitely a gonner by all the blood on him. Turns out it was the snakes).
