Admission Fee for DEFCON 19 Shoot?

Re: Admission Fee for DEFCON 19 Shoot?

My hands hurt just thinking about 50 rounds through one of those. My gear's mostly prepped, just need to take at least one more trip out to ensure scopes/sights are on, buy a bunch of ammo, and we're good.

And a month later is still hurts to make a tight fist. I'm getting some shooting gloves.

Anyone wish to shoot slugs out of a shotgun with a 6" barrel?

Why yes sir, sounds like a marvellous time.

Out of pure scientific curiosity, just how accurate is it?

Did you know barrel length has nothing to do with accuracy? It's the sight radius that affects your accuracy. Regardless, I shot 12 rounds of buckshot with it and there was no target left after that.

I'm not as familiar with firearms as many people at defcon like you, but I have a question related this statement:
Is this claim true only with shutgun, and firearms without rifling? I though rifling was added to force a spin on solid rounds fired, to improve accuracy. Certainly a longer barrel is not the only way to get sufficient spin, it would make sense to gradually spin up the round over a longer distance. Your thoughts and experience? (If this becomes a fork in discussion, I'll copy/clip it out to continue elsewhere.)

Thanks!

The spin is a fixed amount, like 1:7 or 1:9, so the bullet rotates one revolution for every x number of inches it travels. The rifling needs to be in the barrel for this, which eliminates most shotguns, black powder guns, etc. I don't think the WWII 45ACP Liberator had a spin as it was meant to be used from 2 feet or closer.

A shotgun round that has rifling or a similar sabot round is only as good as the rifling on that particular round and the conditions under which it was made. The rifling may change every so slightly with each round, whereas when the rifling is in the barrel it will never change except to wear over time.

For my statement I should add that once the round is stable in its spin, which normally happens when the entire bullet is fully in the barrel, the the advantage of the barrel length at that point becomes the added velocity from the restricted gasses. The longer a barrel, the faster the bullet will travel, until the gasses stop expanding and drag becomes more of a factor on the bullet.

Thanks again for your well composed and detailed answer. :-)

Happy to help. I plan on bringing dead hard drives to the shoot, we can see how hollow points do. Remington vs Seagate, Western Digital vs Winchester, Maxtor vs Saiga....

Thanks, that cleared some things up for me!
