Thank to everyone for their input.
The Alliant guide states max charge of 3.5g of Bullseye for a Speer LSWC 158g. If I start about -10% that's about 3.1 so I'll try that range.
Also says max charge of 5.7g of BE for a Speer 230g TMJ RN (same as FMJ?) - seems high given your comments. Lee says max 5.0g of BE for a 230g jacketed bullet. -10% brings me down to the 4.5-4.6 range you guys reco. Is Alliant just wrong?
