Maybe check the Sunday evening auction from a Saskatoon gun shop Steve. Three 100 count boxes of Federal 210 LR primers sold for $280 last night, I never tuned in on time to see but 1lb of H1000 usually goes for north of $300.
Probably used in .338LM for Long matches out at the Nokomis range where I hope the prize money is worth the $1 a pop primer and $4.50 a shot powder.
