Griffin .22 ldc 17g slugs?

In fact I had a notos with a 380mm superior, from 730fps to 840 they shot well enough to take 100s of souls.
After I slapped on a 600mm they tightened further. Out of the 600 from 850-900 they shot just as well as jsb pellets. About 1.3moa at 100 if I had the gun on a lead sled. Frequently plucked squirrels out of trees 65-93y from my elevated perch at my preferred hunt. I don't foresee disappointing results. Start shooting them at 870 and work up. Every barrel is unique.
