[QUOTE="jmden, post: 847111, member: 1742"] I'm starting to wonder about Retumbo as well, Roy. I loaded some Kirby fireformed Lapua brass tonight to 99g (dropped 1g) and -.015 (standard load, just dropped a grain), same as the other load that ave. 2954fps MV. After two foulers to foul a clean barrel it went 2930fps 3x. Still had too much pressure. Will drop to 97g and try that tomorrow. Quite frustrating. It's as if the powder became a faster powder, whether loaded in a case or in the powder container, in the last 4 months since I worked with it. Seems to be pressuring out at lower charges and velocities. Is this a Retumbo thing? Anyone else besides Roy and I noticing anything with Retumbo lately? [/QUOTE]
