So, I have a pre-air force TM1000. It is tuned by Alan Zasadny with a nice moderator. Has .177, .20 and .22 barrels.. I've been using it for open class silhouette and compared to my other class rifles (FWB300 Tyrolean for target and Air Arms TX200 for sporter)? It is really bulky. It's not so much the weight, it just feels awkward shooting offhand. Here's my question, Does anyone have ideas about a stock which could be bought or made which would be more ergonomic for offhand shooting and I could just save the original stock for field target?
