Slugs in a sub 12fpe brocock commander, has anyone done it? And what where your results?
I shoot 10grain Zans outta my Leshiy Classic 177 and they group well even at 800fps (14fpe) and might hold up at even lower speed.
I do have a question related to those subject to a 12fpe limit: Is this built in to the guns that are sold, meaning that it is based on the muzzle energy of the most energy efficient pellet? The reason I ask is that if I tune a gun to shoot a pellet at 12fpe and then shoot a slug, the slug will leave the muzzle with 11fpe on the same tune, due to increased friction in the barrel. So, is it legal to retune to get 12fpe at the muzzle with a slug?
Thanks for the info. Obviously the guns are delivered with headroom for the most energy efficient pellets (heavier diablos typically). Therefore when you shoot a typical pellet, you get only 11fpe. Slugs get the shortest end of the stick because they’re least energy efficient due to the fact that they contact the rifling along their entire length and therefore have the highest frictional loss. Do the authorities perform random checks of your guns? Are there many cheaters?Hi weevil
In the uk alot of guns are only 10.5 ftlb from the dealer for some reason or another " maybe they think people won't notice or err on the extreme side of caution?
The rule in the uk no matter what pellet leaves the barrel it cant exceed 12ftlbs
That is a 14.3g at 600fps =11.5 there abouts and a 22g slug at 485fps = 11.5 ftlbs there abouts
As for friction god knows

Bjesus weevilInteresting and on the contrary, I greatly admire anyone who crafts their their own wares, be it ammo, food/drink, a vehicle or house. I have dabbled a little with beer making but our water isn’t good for that. However, I do make make my own wine and have several varieties of wine grapes in my garden. Largely because after living in Europe and returning to the US, I could not stand the taste of the sulfite preservative in our wine!
Your slugs look great and that’s something that I’d love to try sometime. Certainly, if only the bands engage the rifling then the frictional loss will be lower. I jumped on this thread because I’ve been on a mission lately to craft the lowest power rig that I can use out to 100y. I have a problem with rats that come from a canal behind my house to my chicken coop. While it’s legal for me to dispatch them with 80fpe slugs from my 22 M3, I prefer to use the least power possible for safety. So far, I’m down to 18fpe to maintain ~1.5 moa at 100y with 10grain Zan slugs in 177 and 0/12 rats have survived the tests.
