Hey
I just bought 250 rounds of KO's 23/4 slugs. 1600 out ouf the muzzel, but, on the front of the box it says"for smooth and rifled barrels" how can this be???? has any one shot these out of a rifle barrel??? I have a rifle ckoke tube on my 870 thats as close to a rifle barrel I can get in a 12 gauge. now a 20, my NEF UHS is it for deer. These I got a real good deal. Please send input.
Thanks
Bearbeater

Yes, they work well in BOTH rifled and smoothbores. For that versatility the price is in labor after you shoot them. They are made of hard lead and a good design. The expansive base wad is the secret to their accuracy. (Within reason 65-75 yds).
Just resign yourself to a bit of cleaning in the rifled section of your choke tube. I have prepped bores (that are pristine) with moly fusion and it has been no problem to clean at all.

The Brenneke K.O. is best in a smoothie.
It will work in a rifled barrel but leading could be problematic.
Good ammo and fair prices.
my smoothies get 3 inches at 75 yards.

Hey 106
I get about the same. The price is right also. My 20 is very accurate with hastings 2.75 sabots, its an NEF UHS and that is all I need for deer but the price of the sabots are enough to say " oh my " I am going to reload my own. I have my own design for a slug. I dont want to disclose what it is right now but will experiment first then maybe mass produce the molds. I dont want to get into producing ammo just parts. I do alot of reading here and other places and the internet has open alot of avenues for us to exchange Ideas. My prototype mold will be made in a few mounths and will start experminting this summer.

Hey
All of us must agree that we are not going to be efective at long ranges. people being people will try to move their fence posts back to see how far they will go. I am not doing that. I want an accurate load, avery accurate load at 100yds. Also to do away with fouling, Keep cost down, lower operating pressures by 20 percent, and increase velocity by 150 to 200 fps. I know it sounds crazy but it can be done. when I do it or see the results I will let a;; know but all of you will smack yourselves on the forhead and say why didnt I think of that. My only problem is the slug is a bit to heavy maybe 650 grains.
Thats all for now.
Thanks
Bearbeater

Thanks bearbeater! :D
Best of luck to you.
When you get the slug up and running maybe you will post something here for us?

Bearbeater,

How about an existing slug of 375 gr.(Lyman 20 ga) launched
out of a 12 ga. platform ? It can and has been done. I'll give
you a few starting clues.

Lyman 20 ga.Sabot slug (Get the oversize ones from Gardners)
Resin filled cavity with release agent in void -Coat of wax
will help the plug pop out when fired. Knurl before filling
Knurled rear driving band only.
Winchester Primers (209)
Powder (now this I am still playing with) WSF or Blue Dot.
Federal Gold Medal Hull (Fold Crimp)
Federal Wad (Punch a 1/4" dia. hole at bottom of wad slit)
(Use the thick walled brown ones.) 12S4 Mica dusted.
The Duplex Sabot from the wad cup of a BPI LBC wad.
Yes .you will have to trim it to size to wrap around. Thick end
towards back. They are tapered in thickness. Split in half
vertically.
About 40lbs wad pressure.


Are these accurate ? Well yes and no. Short Range has
not been a problem (50 yd) . Beyond 100 yds it is a crap shoot.

The real problem is the rate of twist/velocity of the 12 ga barrel. It is a bit too slow at 1-35 for the weight of the slug. The quicker the twist the better the long range accuracy. It does improve in a 1-32 so I am sure the benefits are there. I am curious if anyone has tried this combo in a 1-28 twist barrel. I do not have one in that configuration.

Let me know. I have been at this for a couple of years.
I have NOT found the ideal combo YET !
