What's with those sizes? I went and slugged my BSA barrel and it's 5.57mm through the choke (could have been slightly bigger). LW says 5.62mm for their airgun barrels. Looks like those slugs are seriously undersized at only 5.51-5.53mm? To my understanding a pellet with 5.52 size refers to the pellet head which is supposed to be nose riding while skirt seals up to grooves, now if they make the whole slug body bore riding it gets easily tilted off the axis when loading and you get horrible grouping.

No difference from the guys who have been doing it awhile and they work well.
Hope they are better than their Rabbit Magnum lls
i don’t think they are beginners

Hi Riku is your BSA barrel a current barrel both my Buc and Urban .22 barrels slug at ~.219 groove at breech and ~.217 at groove muzzle/choke..? using a Fowler Micrometer... My AT44 long slugs ~220 groove at Breech and is choked to about ~.215 at muzzle... has .215 bore at breech... all three like the 30g 220 BBT sized at .217 best...in the NSA and H&N I want to try both the .217 and .218 in my rifles to be thorough... plus if it is the .217 that is preferred by a given rifle... then I want to see if the .218 size down and shoot just as well... In the end I like the independence of cast so am not in any hurry tho... I am glad for the fact that more options are becoming available and slugs are not just for big bores any more... Heck was buying molds before had the rifles to send the rounds in .217-.22...in the end over the last 3-5 years it was folks like Doug(Pakprotector) Nick(NSA) the African 100m indoor group and all who took the chance on the 30g Bobs Boat Tail molds (and others)that proved it out enough that got H&N to see that it is very workable...
Ric, something is wrong with that listing. Those specs are for the hornet barrel. Knife
