[QUOTE="lancetkenyon, post: 1485416, member: 68875"] 77.0 is over Berger max load. But just about Hodgdon max load (I know the 210s are 78.0gr H1000 max load but don't recall the 215 max). But max in your rifle can/will vary. Max case length is 2.620", so trim to length should be 2.610". I wouldn't go much shorter than this, especially since the .300WM already has a fairly short neck to begin with. And I bet your virgin brass was 2.610" or shorter to start. So no need to trim. Everything else sounds about right. Your rifle just must max out at 76.0gr. I wouldn't go higher if you are getting sticky bolt lift. Every .300WM I have loaded for using H1000 has been right in the 76.0-78.0 for an accuracy node at the higher end using either 210 HVLD or 215 Hybrids. Just finished loading for one yesterday. Nosler brass Fed 215 Mag 77.5gr H1000 210 HVLD 2.690" CBTO (Win 70 w. Short mag box, but about a .160" jump is where the rifle liked them) 2941fps from 26" barrel [/QUOTE]
