| Is anyone out there loading the 125gr SNS casting coated bullets? I am helping a friend out, we started with 3.4 grains of Bullseye at 1.115 OAL. They were jamming and would not pass the plunk test as I did not have the barrel available when I loaded 10 test rounds for him. I had my Lee hand press and a dummy round, I had to drop down to 1.091 to pass the plunk test, anyone have an idea on how that will affect pressure? The gun is a full size EAA witness. Looking for some input and new starting load if applicable. |

I'm using a similar dry-lubed bullet (The Blue Bullets) in the same weight using 5 grains of Bullseye in a Glock 19.
As for the rounds failing the "plunk test" it's been my experience that dry lubed round nose bullets from pretty much all the folks who make them have a very blunt ogive which can cause chambering issues if the chamber is "tight". I shoot mine through glocks so I'm not experiencing this issue. All I can say is to use the gun's barrel as a chamber check gauge and not a SAMMI-spac gauge. The EAA's chamber may be more generous than the gauge. If it isn't, you'll have to either adjust the powder charge accordingly or use a bullet with a more "conical" shape. If all else fails he can sell the bullets (shouldn't be difficult) and try RMR's RN plated or jacketed bullets. |
| I am not sure about the powder, But I was casting some 120 grain Lee TC bullets a few weeks ago and would powdercoat them. I had too seat them at 1.040 to get them to pass the test. I was using longshot powder. Generally as long as you arent near the max, you should be ok as far as seating depth. |

Looking for some input and new starting load if applicable. Sounds about right. I load the SNS 125gr to 1.085" in my guns - can't go longer. I don't use bullseye with them at the moment (mostly WSF or Titegroup currently), but in general, find I'm loading on the lower end, at or just above starting loads, to reach published velocities for higher range loads and/or make Minor power factor. A chrono will help. |
