Even though they are plated, the thickness is enough that standard reloading data can be used. That's the theory anyways. Until I get the MGM barrel, the fastest twist I have is 1 in 9. For fur or plinking, the cost makes them an attractive option.
Looking to hear from anyone who has tried them. They are $60/500 or $120/1000. I picked up 500 to try.
