Last april there was no fifty to be had at any price. Last october, there was more fifty than at lake city ammo plant. My point is, there is not much coming in from overseas, so it depends if prices have gotten high enough for shooters and dealers to open up their private coffers. I took 2600 rounds of fifty to sell last october, and brought it all back. A lot of others did the same. I can promise you I will never take another round of ammo to try and sell. It is a royal pita. Plus it doesnt matter what it is selling for, how are you gonna replace it.
There was a lot of 303 there last time. Century has 54r, although it is bulgarian and I have heard of concerns about this ammo. If you are going to buy from century I much prefer having it delivered to my house for free as to toteing it home from the creek. I always take ammo to shoot and on the good years, bring home more than I took. The last year wasnt so good in that regard though.
I need 8mm, but I dont think there is going to be any there. The last I saw was outrageous. I dont own a gun that cant be converted to something else before I pay .60 a round for 8mm. If I am shooting .60 a round ammo it is going to be some of the 308 lc I have.
Good Luck
