View Full Version : Point of impact from slugs to birdshot?

August 19, 2001, 04:43 PM
Howdy all,

I am a new shotgun shooter and have only put slugs through my shotgun (Mossberg 590A1 Ghost Rings) up to this point. Reason being that I shoot at an indoor range and shot would not be a really good idea in a bulletproof room! :eek: I currently have it sighted in to hit point of aim at 25 yards. I will be going to a shotgun class in three weeks, which will be mostly birdshot and was wondering what kind of change in impact to expect, if any, between the birdshot and the slugs. I know that all shotguns like different ammo and will shoot differently because of this. What I am looking for is if there is a known change of impact when going to the different load.

Thanks in advance,

No set formula that I'm aware of.. Never tried the buck/bird comparison, but slugs and buckshot often have major differences.

As you mentioned, testing is the only true solution.

It's an inconstant variable, EQP. IME, slugs impact higher than shot, even buck. For example, my HD 870 puts slugs maybe 18" higher than the center of a shot pattern at 25 yds. Yours WILL vary, and changing loads will make it vary more, not less.

Thanks for the info guys! I guess I'll figure it out when I get to the class.

Thanks again,
