Thread: 7x57 subsonic

Yes at best there is about a 50% chance I will get it right first time, I have managed that with making subs for a couple of other calibers, but I would prefer to start in known territory here and not have to shell out for 100 projectiles which is the next step if first attempts aren’t successful.

Given that it’s trail boss I would also be interested to know any recipes people may have used for 175s in 7mm08
(Note I wouldn’t swap other powder data between calibers)
