Hi, First time posting. Just received a siamese mauser action and was wondering if anyone would know what the maximum oal round it could handle. I have in mind 30/378 since I'm going to have to have a barrel made. I'm not interested in 45/70. I want a modern type round. I'm also having problems matching up parts made for mausers. No one lists the siamese as it is different in small ways. Any input would be appreciated.
