One of the guys who just built one on a carbon fiber shot one hole while fire forming with 53 grs. of H4831 and a 140 A-Max. I believe the velocity was 2870? This was with the 6.5 for others benefit.......Rich
You might try reducing the charge a little more if you want velocity even lower but I don't know if I would go much below 50 grains? There have been cases where not enough slow powder can be as bad "or worse" than not enough. You can get a secondary explosion that really spikes pressure! You might try some powders in the 4064, or 4895 range too. It would be nice for someone to develop some low pressure (kid) loads. If I get time, I may work on that. I have used 4198 in several of my rifles to test bullet expansion at low velocities, but mostly in the 1200-2000 fps range. Trial boss has been used for reduced loads, because it fills the case up, but I don't think you can get velocities in the range you are looking for. Again, BE CAREFUL when you are messing with reduced loads.
