Is JSB Heavy MKI now JSBHeavy MKII?

Old thread. Has this issue been resolved or is it ongoing?
Are there other options from FX H&N or EdGun that don’t have the same problem?
Looking to shoot the 33.95 in a RTI with a 24” LW.

Kinda.... The King Heavy (Mk1) looks very similar to the Mk2, but like has been said in previous posts on this thread, the Mk1 skirt is a larger diameter than the Mk2. The FX Superior liners are designed around the Mk2. Most FX Superior shoot the Mk2 better. As far as the Daystate .25 A.R.T. barrels, it seems 50/50 that they like the Mk1 or Mk2. My recent .25 Red Wolf HP likes both, and under low or no wind conditions the accuracy is similar. But once it starts getting windy, the Mk1 measurably outperform the Mk2.

Guess I'll order a tin of each to see how they work in the LW. Thx.
