Thread: Kimber Montana 308 Load Development

Having trouble replicating groups post suppressor. Have made some errors and learnt a bit along the way. I use a Sinclair priming tool...expensive but good kit. Realised I hadn't properly adjusted washers and was putting a slight crush on the primers. Easy fix but ignored it for longer than I should have.

Also got lazy with my hold and realised I could shoot better with the overhand scope hold method. The range practice isn't doing any harm.

Got low on CFE223 so trying RE17 as have plenty. Apparently great with heavy 30 cal bullets so my 168gn LRABs may have been at the lighter end of usability. Started at 47, 47.5 and 48gn with Fed match primers and no pressure signs with speed close to 2600fps.

Today tried 48.5 (2603), 49.0 (2636) and 49.5gn (2640) and again no pressure so will try 50gn and then running out of case to hold it. Groups not there yet...may have to try ELDMs.
