Why did you change the barrel on your Mrod?
I use the same pellets, with my stock Mrod barrel and must admit that it's the most accurate pellet (or should I call it a "slug") that I've shot through it!
TBH, I don't know why it shouldn't work with the LW barrel, it's the same .22 diameter (or it isn't?), they work perfectly good for me.
I bet you and me are the only ones on this forum that use these, the rest of the guys I've noticed are not so keen to get products directly from overseas.
They'll just stick to USA made stuff.
Try to clean your barrel, maybe use some lube and I bet you'll have amazing results.
