How’d the thread go from discussing the GK1 to the Huben K1? Are the last few posts accidentally calling the GK1 a K1 or are you folks actually discussing the rifle instead of the pistol? It’s a bit confusing to follow.

Who has gotten acceptable results shooting JSB KO slugs from a GK1?I'm not sure, but maybe the JSB Knockout MkII qualify as "girlie" with their mini-skirt?

Not lead striationsWhat you folks are referring to are Striations, not rifling. They are caused by lead smearing through friction. Those bores in the mag are smooth. The mags are the same in both the GK1 and K1. Although I have only GK1s in .25, I can assure you the mag bores are exactly .250 in diameter checked with a precision set of pin gauges, which I own. To prove my point, remove your mags with these striations and clean their bores with Hoppes number 9 and a bronze bore brush and see for yourself.
My apologies, both my V1 and my V3 have those grooves. I missed them. I did however recheck the bore size in both my 25 cal. V1 and V3 magazines. The sizes are the same .250 go .251 very tight almost no go.. My barrel land diameter is .247 go .248 no go. These sizes are the same as I reported earlier in other threads here on this forum. Those grooves are NOT rifling, just grooves.Not lead striations
This is a 25cal mag I pulled from my gk when I switched it to 22.

You are correct, they are not rifling. I said they are rifling LIKE lands in one of my previous posts on the subject.The rifling like lands in the mag hold the slug.

I have posted in other threads on the forum a way of ‘knurling’ common slugs that works perfectly for the huben mags and transition to barrel (forcing cone). And are easy to load.
