First cold shot through a suppressor
Over the last few years I have been concentrating on subsonic rounds through various suppressors in different calibres.
Prior to that all rounds had been supersonic as suppressors are unrestricted here (New Zealand) and I use them on F class rifles in competition and on all my rifles for hunting/ varminting.
I was dismayed to find that once I went below 1200 fps I could not replicate the astonishing groups I had read about when including the first COLD clean shot. This regularly dropped between 4-6" low @ 100 yds of the remaining group. Sure the other 4 rounds would print in 0.5" but pointless for hunting when the bl is cold.
I would dearly love to get to the bottom of this and i am heartened that this is the place to start.
