Wow! I've never heard of this practice.
I would guess that many if not most of the short range BR shooters around Western Colorado use 31.
Some blend Norma 200 and 201 when they can get it.

It is very dry here, with many days having a low Relative Humidity of well below 10%. N-133 get bat-crap-crazy at 100*F and 6% RH. I set out some 133 yesterday on the back patio as I was enjoying a cool glass of iced tea in the warm sunshine. I set out 26.0 grains of 133 in a jar and weighed it every 10 minutes. Within 30 minutes it lost .26 grains. Some days 133 works, some it doesent.

31 works for these guys........... I admit I get my butt kicked by the 31 shooters every match but the snakes in my head are worse when I put a blend in the hopper.

Great Info. TKS for posting that @Mulligan The thing that I can't wrap my head around about blending is how can you get the same blend from round to round. It isn't like mixing water and sugar; or am I overthinking this.
The only way to handle that intelligently is to have two separate containers of known quantity before blending.

Incidentally, combining them into one container is probably the best opportunity to blend them well. I don’t have clever details but I would start by slowly pouring both through a large funnel simultaneously, letting the kernels intermix on the way down. Once dry material is in the same container it’s harder to mix evenly.

I for one will probably never try it because it’s just a bad idea for a general reloader. As are 70,000psi loads. They’re out there but I’m not going to do it.

I get gremlins in my head when I have a blend at the bench, just the way I'm wired. I have shot 31 and it shoots very well in this dry climate........ it just doesn't get weird......... I'll leave it at that.

Yes, a pound of each all mixed up..... easy as that.

The exact mix isn't that important, Dan Dowling has been shooting 31 for a good while now and after thousands of rounds, you know it hasn't been the exact each time or even close, yet he and @memphistransplant and a host of others keep mopping the floor with my arse.
