I have now finally got loaded some granates for the 10 bore manton. I still haven`t heard from Rocky mountain yet...so I have got some plastik hulls 3.5" instead, shorten .25".
My first load will only be 200 grain Swiss No 4 (1,5FG) so I can feel how the recoil is taken by the gun...but the next one will be fullpower loads of 270 grain (10 dram). I`LL keep you all posted for sure. If anyone has some last words for me, it might be a good idea to say èm now...hahaha
