.22 25.4gr Monster Redesigned, which superior liner; Heavy or Standard?

the OP just means the batches of monster redesigns made this year I think.

All the latest batch 0.22 25gr monsters I've bought lately are absolutely terrible in my guns. Including a delta wolf with a barrel supposedly designed around them. It'll put three through the same hole, then a flyer 5cm/2inches off at 50m. Doesn't matter what velocity etc, the flyers are there.

@BSJ unfortunately my superior heavy barreled impact doesn't shoot the latest monsters well at all. Similar results to the delta wolf really. My compact has a superior liner but I'm shooting 16gr so well out of that I have never bothered with trying redesigns - not that I'd ever risk retuning to try these junkers anyway!
 
Which 16gr are you using? I just got everything shooting well at 100 yards and was counting myself lucky to get my hands on 3000 monsters.

Now l'm stuck starting over...

I'm using the 16gr Air Arms variant of JSB. I find they tend to be a bit more consistent and, for some reason, arrive in South Africa less likely to be damaged.
