9x23w,
I have shot a few 130s with IMR7828. I don't recall the powder charge, but they were running @ 3,671 max. Decent groups too.
Sniper2,
I shot some 130s & RE25 as break-in loads. They went into .522". I was thinking that was the 7828 load, but I checked my data book & it was 90gr of RE25.
Make SURE you back off loads & work up. The 7RUM spikes pressure VERY unexpectedly. It can bite you in your grinner in a hurry.

ebb,
Darryl told me about the WC872 a while back. I need something that'll shoot tight in hot weather, since the competitive applications will mostly be in the summer in the midwest & mid-south.
If I get time to try it, it sounds like a very good possibility for cold weather hunting.
