The last gunshow I was at the 762 ammo was cheaper than the 223. Anyway that is not normally the case nor will it. I found the stock a little bit on the short side so I got a fibreglass stock off of Hungry. The colour of the stock sucks but Kralon paint sure makes it look good. I got the rooster oprod guide and a new spring as well as a bolt buffer. There's a lot of tinkering you can do to make things better. However, I was knocking the 200 metre gong offhand regularly when it was out of the box. So for 465 bucks at the door with a case, its hard to beat. Trigger is OK. Rear sight can work loose so you lose elevation. LOTSA SUPPORT ON SITE FOR THE 305S! If you want a love in heres the rifle. You can hunt with it anything in north america. Just dont get the heavy bullets.
SKS, its cheaper and so is the ammo. Cheap ammo usually has corosive primers so cleanliness is a good idea. Immediately! Stock is ok. You can upgrade it but the stock is about as much as the rifle. Trigger is BARF!!! Needs lots of smoothing but if you want to practice on something to develop good trigger work, this will help. Ive put the spring kit in and did a bit of stoning. It helps. Theres are websites that will help with that but it will never be as good a 305. Sights, upgrade to williams sights or theres others as well. The williams is nice others I dont know. I prefer the stripper clip model of sks but other people have different preferences. Past 100 metres, accuracy sucks. Also recoil is light.
I have both and shoot both. The SKS is my fun gun, ammo cheap, lotsa rounds downrange. 305 still fun, accuracy is better, recoil is heavier and I could hunt with it. Can hunt with SKS too but deer is upper limit and not with surplus ammo either.
