M1 Carbine Power

[Tired Retired]

I am exclusively using Remington 110 SP for reloading right now. (Bought a bunch at the same price as Rem FMJ). I have not had a single problem with any feeding into any of my shooters. I also have pretty smooth feed ramps on my shooters. (A couple came with park on the ramps from arsenal rebuilds so I polished them.) For commercial SP, I am also using Remington SP's.

One thing I noticed is the differences between some bullet manufacturers in how much lead is exposed in the SP's. I do not know if it is a quality control or a design issue. Last night I was looking at the rounds in a box of Privi SP at Cabela's. The exposed lead was uneven around the circumference of the bullet. It also seems to extend lower on the bullet than most other manufacturers. I would think that this would increase the chance of the bullet tip dragging on the feeding ramp.

Of course, all of this is conjecture. But next time I go to the range I will be sure to stick my face really close to the bolt and slide handle so that I can see what is actually going on inside.
