How about a BC of .39 in .257cal.
Now we are talking! What is the weight and length of them? where did you get them from? What are you shooting them out of?

My slugs 2.3 grams in .22 caliber have BC around 0.15
What is the weight on them? More information?

The challenge of it, pushing the limits..... One could argue why use slugs at all and not just pellets, if you need more than pellets then just use a 22 lr at that point.

Holy smokes Loren . Those are some slippery pills indeed . I would imagine a 1:10 or faster twist rate is needed for a bullet that long .
As far as getting a powder burner . Where’s the fun in that ? Go to store by some off the shelf ammo , load and shoot at 1.50$ per trigger pull . And still wonder why you can’t get under an 1” at 100 yards . Shoot over a chrony and see that the factory ammo has an ES of 250 FPS in one box . Look into reloading and see that once you have everything bought and time invested , you could have just bout a “pellet gun “ that did the same for a fraction .
Thats my story and I’m sticking to it .

I cast them. Length is 1.028 and 112gr. Yes needs a 1:10 or faster twist rate. My Texan has the power to throw them, but sadly not the twist rate to keep them stable.
It will stablize these with a .31 BC. and 86gr.

Just ran the miller stability formula, a 1 in 9.5" twist would be optimal for the 112's.
What twist rate is on the texan?
