I've only seen it by the brick on store shelves and I snag it up when I find it. The last one I found was @ ACME in Seymour. Their cash price was equivalent to mail order + s/h.
I hear that the MT is going to change manufacturing plants and like the ME, also be made by Eley in England. The stuff I have has the waxy coating and is made by SK in Germany.
The last I heard SK was making Wolf but that was a long time ago. There may be something about it on Rimfirecentral.
Wolf was made by SK for a long time. But the recent discussion I've seen is the Wolf moved the contract to Eley.
I've yet to see a field test report on Eley-made Wolf.
My existing supply of Wolf was the SK-made stuff and it's excellent.
