My father lives in an area that is limited to the use of shotguns and muzzleloaders. I finally broke down and dedicated a Remington 870 to be a slug gun. I put a Mossburg rifled slug barrel on it, scope and custom thumbhole stock and fore end. Anyways, now I am looking at a slug round to shoot through it. I've shot 12 different loads through it now and all shoot about the same... So, I am looking for people's personal experience and advice on what slug loads they have liked. Particularly knock down power and accuracy as well, but so far all the loads I shot seemed to shoot about the same at a 50 yard target. I will have the ability to make 200 yard shots, so long range accuracy is appreciated. Thanks!
