Cudgecritter

Hey fellas, my name is sam and i'm 17, i'm currently own a 6.5x55, but am in the process of selling it to buy a 308. i'm very keen on deer hunting, and i have acess to a fair bit of land, on our own place and neighbours etc. I ask a lot of questions, and am looking for any help or advice i can get on the topic of walking up sambar. A local fella who might even be a member on here? Raas. Has helped me a lot but ive asked him just about all i can. I'm keen to join in on any backpack hunts if i can. I also have a GSP bitch who im slowly training on deer, but she makes a lot of noise in the bush, any advice from blokes who have working gundogs on deer would be sweet
