Hi. I can't afford a Chronograph so I was wondering if anyone has chronographed the above boolit and powder and what powder charge you used. I'm trying to stay around 1100-1200fps. I've looked at Accurates Load Data and it showed for the Trapdoor and Similar 23.4g 1,070fps (max) 26.0g 1,217fps and (max) 16,100psi. For Standard pressure it was 25.2g 1,265fps (max) 28.0g 1,400fps (max) 27,900psi. I would shooting these loads in a H&R Buffalo Classic. ANY data would be greatly appreciated. Thanks
