The Sporting Life are very common, especially in 12 and 16 bores, I would hazard a guess you will find some without too much problem.
Good luck with the hunt, if you get stuck give me a shout I have lots laying about.
My opinion only:
More then $2.00 each, but no one can honestly say what they will bring.
Unfortunately, price guides have little to do with retail value. I have yet to see a price guide “buy” or “sell” a single item in a given area… That is why they call them guides. They have very little understanding of the current marketplace, current values and how hard it is to find an item, cost of inventory, expenses, much less the laws of supply and demand on all the items they list. Example: if a box of 20 (30-30) Winchester is selling at Walmart for $20.00 or $1.00/cartridge and the price guide says it is only worth .50 cents, do you think Walmart should lower their cost?
Cartridges are like everything else in the world (food, stocks, gas, etc.). The law of supply and demand is what controls the retail price, not a price guide. It all boils down to what a person will pay. The larger the market, the higher the demand, thus the higher retail price. Of course, if more than one company is selling the item, then it becomes a “what’s your price game.”
Price guides are written on paper, on a given date, by a person who may or may not know what the current market conditions are on all the 1,000’s of items in the price guide. They are not written in stone, and no one person can keep track of all the calibers in all the markets. That is why I feel they are the only articles in the IAA Journal that need to be read with the understanding that they may not be correct.
I’m not slamming anyone, this is just my opinion. I love the Journal and Chris Punnet is a “HUGE” asset to us all in the IAA, and works harder than anyone I know in the IAA. The market will always set the price of an item, not a number on a piece of paper, as no one person can ever dictate the value of an item.
