Well I hate to say it because they are both over Nosler max. So if you try these be sure to start LOWER. I kept adding more powder and the groups kept getting better until I got to these points. Nothing real exotic...Id say a lot of folks have used these exact loads and gotten great accuracy out of them. The 130 gr NP load was Fed brass...WLR primers...59.7 gr of H4831sc. The 150 NP load used the same components and 57.5 gr of the same H4831SC. Id say that half the handloaders out there use these same loads as 4831 shoots like it was made for a 270.
I havent chronied these so I dunno the velocity but I would think its below the book speeds quite a bit as this particular gun seems to have a slightly loose chamber. Both loads will go slightly less than an inch. Running around .7-.9 depending on how the loose nut behind the trigger performs..lol.
