Home Forums Reloading Big Game Rifles Norma URP?

Was wanting to try URP in the 6.5 creedmoor, seems like it makes really good speed with different weight bullets. H4350 is hard to find, and I had a lot of velocity difference with RL 17 going from 85 degrees to 45 degrees, about 100 fps. Although I'm starting to doubt the accuracy of the cheap shooting chrony. Magnetospeed will be ordered shortly. My main question is how stable is URP powder when it comes to temp stability.

I'm curious about URP, too. Even though I have a keg, it doesn't get cold here, so I can't simulate winter hunting conditions up on the rim.

FWIW, it looks to me like something's amiss with your chrono results. It _does_ get as cold as 45 here sometimes, and my Re-17 Creedmoor loads don't slow enough to mention at that temp, nor has it been like that for anyone else I know who has tested it.

Yeah it doesn't get cold here really either, that's why I'm thinking the chronograph is on its last leg. Most of the load data I've found for URP puts it around RL17 speed wise. I'll re test my RL17 loads when I get the magneto speed. Cause my RL17 load is extremely accurate and I don't want to just forget about it.

Same here; super precise!
