Went to nearest supplier as was low on cartridges,the choice was poor so ended up with Lyalvale Supreme Game.I have avoided Lyalvale Express for 10 years as had issues with their clay loads and they would change a 'deformed batch'. Well blow me down these 'premium/expensive shells' whilst kill well literally blow bits of the OUTER casing up the barrel?!!......It was only when I got back and was counting the empties I noticed how worringly bad it was..I shall return both the offending box/empty cases and remainder of the slab. It cannot just be bad luck though that twice I have fault and both times it has been this respected manufacturer.....I am an old luddite so have no idea how to upload pictures but at least half an inch of outer casing has simply been blown up the tubes(and I don't mean the crimp)........verging on dangerous. These were their 30g 5s(it was that or plastic wad 8s and I dont shoot plastic).....I don't like 30g loads in a 20........it was fired throw a superior proofed 3 inch chamber so was not wrong cartridge in wrong gun reasons...........Has anybody else had this issue as I cannot believe it is just me?..Anyhow Lyalvale will be waiting more than 10 years this time before I use their product again.....
