I found it to corrode my RCBS powder thrower.Brother Joe & Sister Gwen Salas has been visiting the rest homes for the elderly in Gainesville for many years now, and the Lord has used them to be a blessing to many of the ones that live there. I have a kerosene heater and I would dump the unburnt kernels from the muzzle on top the heater and in a few seconds they would poof, make a little spark and cloud of smoke. I've shot it with snow on the ground and after a dozen or so shots, there is a black racing stripe in front of the bench. Slow velocities, but sometimes that works O.K. Primers were rounded and showed no signs of excessive pressure.Īgain, this is for high pressure rounds out of a strong action. the experience of shooting these is that they are milder and lower in recoil than the surplus I was shooting at the time. Extruded powders of large grain, like 5744 seem to stay put better than, say, a ball powder which is easily scattered. The purpose of always using a compressed load is, much as possible, to keep the powders from mixing, hence, "diluting" the ignition of the faster powder and causing inconsistent results. Eventually you'll get to where the amount of unburned powder in the barrel has all but disappeared, your velocities and POI are coming up and it's pretty much done. If your barrel has a lot of unburned powder in it, increase the amount of fast by a grain or less and try again. It's just a matter of putting in a few grains of your chosen fast powder and filling the case with 872 so you get a compressed load. The initiator I used was 4759, but 4198, 5744, Reloader 7 and similar fast rifle powders will work well. My goal with the 7.62x54R was to get a clean, powder-free barrel and a POI/velocity the same as surplus ammo with bullets of the same weight. You'll want to check your results with a new lot, as you may need to fine-tune your load. Also, the warning about lot-to-lot variation is correct. What has been said about using a faster propellant as an initiator to increase pressure and temperature to get the slow stuff lit is spot-on. Even with heavy bullets and mag primers, it was impossible to avoid unburned powder in the barrel and hearing a good bit peppering the ground in front of the muzzle. My own experimentation has been limited to high-pressure rifle calibers, mainly with WC860 in the 7.62x54R.
