I have a 425 & 450 bullet I have sized to work in the Bushmaster.
I have tested OAL and function. The 425 feeds 100% as slick as a spitzer. Its odd cause its a WFP profile. The 450 is nearly the same as my favorite 457191 Lyman bullet. Slightly smaller meplat. But altho it feeds sometime you get that “faulse start”
I was concerned with body bulging from the long boolet. But it did not the case. Cases look 100% normal.
Next stage is powders and charge weights.
Anyone been here before?
