Well I tried out 3 shotguns firing slug this afternoon. The 870 Remington Wingmaster with a 20” slug barrel. The barrel is fitted with a Rem Choke in Imp/Cyl. The 870 is fitted with Aim Tec saddle mount and a Aim point Micro H1 red dot site. The site has a 4 Moa red dot
The second gun is my Merkel 211E combi in 12-7x57R. I’m not sure what the choke is on the shotgun barrel but I think it is quite open bored. The combi is fitted with a Kahles scope
The third gun was my Merkel 201E O/U shotgun with 28” barrels in ¼-½ choke.
I shot the targets at 50 mtrs for the 870 and the combi and 30 mtrs for the shot gun.
The slugs are Sellior & Bellot brand. The slugs are 32gr , 12x 67,5 . These are S& B hunting slugs. I looked at the S&B web site and they do several other slugs for practice and practical shot gun. These practice, practical slugs seem a tad slower than the hunting slugs but not enough that a boar would notice the difference. There could be a difference in the build of these slug though ?
The Rremington shot its usual 2” group. The Combi had the first 2 shots within 2” and one shot higher. I know that when I have shot the combi before it did a 2” group. I’m not sure if firing the gun quite rapidly had anything to do with the high shot.
I shot the shot gun with both barrels . The 2 shots to the right were from the bottom barrel, ¼ choke and the 2 shots to the left were from the top barrel, ½ choke.
I have put a picture of a recovered slug shot from the 870. Even though the barrel is Imp/Cyl the fins on the slug are well crushed and I don’t see how they would impart any spin to the slug as it went through the air.
There is also a picture of the lewis lead remover. Notice how much lead it takes out of the barrel after firing slugs
