Congratulations on not having split your chamber yet, Longshot. Obviously you haven't read everything that matters on the subject. Quote of a letter on the subject from Alliant:

"I am Dick Quesenberry, Product Manager for Alliant Canister Powder. Ben and I have discussed your e-mails and problems with Rio primers and our product. I apologize for the difficulty that you have encountered and appreciate you using our product.
We just completed work for the new revision of our Reloaders Guide, which was very badly needed. During this effort we tested all primers in a standard controlled load for both straight wall and tapered shells to correlate their brisance. The following conclusions were drawn from that effort:

· Primer brisance will vary from Lot to Lot within the same brand. Most vary within SAAMI safety limits but Rio was found to be extremely variable.

· We do not publish reloading recipes using Rio primers for the above reason

I have also talked to Kevin at Down Range (who happens to be a great guy) and he agrees with our findings.

If I was forced into recommending load data using the Rio 209, I would have to recommend loading like the Federal 209A and that may still give slightly higher velocities and pressures. ...

Call them an verify if you care to; I don't make this kind of stuff up just to annoy people like you. BTW, the original inquiries involved Promo, Red Dot and Clay Dot.

So why do you say it, Ned? That's what's frustrating. You KNOW that test tells you almost nothing about how rios will compare to 209as in actual loads, but you say they're consistent and equal to a 209a anyway. You KNOW the blue box win209s perform perfectly well now, but you say you found them to be inconsistent anyway. There's no room for misinterpretation in those statements, and if you're not saying them to imply what they do, then why are you saying them at all? You don't say that test has no relevance to how they'll perform with powder. You don't say that win209s perform fine now. You leave them incomplete and they can only lead people to false conclusions. I only ask, and am frustrated by it because people read things like that and take them as they're stated. You're far too smart a guy not to realize that, so I just never understand why you say them at all. It's just... foolish.

You know I don't follow you around the forums to attack you like some others do. I just dispute some of your statements and 'facts' if I disagree with them or find them misleading. Sorry to hear about the Medicare thing. Unfortunately it's happening a lot of places.
Nothing unfortunate about it at all. If Medicare would pay the doctors the amount of money that the service is worth than they wouldnt have to stop taking medicare as an insurance. One caveat to that is if they did pay what it was worth the government would go bankrupt (er).

I like the back and forth between two guys that generally know what they are talking about. Ohsay your season about shut down yet? Whats the outlook for those snow geese? Im still trying to plan a trip out that way to hunt em but none of my buddy's want to pay money to hunt flying carp. :lol3:
NeuOutdoors or something like that. The guy was in Nebraska if I remember right. I really dont want to go with a guide but Im not buying a couple thousand snow decoys for one trip. I know one guy that has family in South Dakota but he gets busy in the spring time.
