.44MAG rifle round ball loads with trailboss?

No need at all for round balls when light accurate bullets for the 44 are made by www.mattsbullets.com

Well worth buying a sample.

I can get the .433 round balls from Midway and count on them being here in a few days. For just about all .44MAG rifles, including my Winchester, one needs .432 bullets. I can only get those from a handful of sources, and usually they want you to buy at least 500 per order, unless they are beartooth bullets, which are expensive. I do have some 205 gr. TCPB samples coming from Penn Bullets right now though.

I will probably ask this mattsbullets if they can size their .44 bullets up to .432. Thanks for the link.

You actually notice a measurable difference in performance when going from .433" down to .432" in a round ball? Wouldn't seem there's enough of a driving band contacting the rifling to make any imaginable difference in 0.001".

No, the swaged .433 roundballs are fine. What I meant was that, for cast bullets, the common .430's will produce poor accuracy and leading in the Winchester 1892, as well as the Marlin 1894 (both micro-groove and ballard rifling) and the Rossi 1892, due to their oversized throats. I've heard Ruger's revolvers frequently have the same issue. I can only find .432 diameter bullets from beartooth, Penn bullets, and Montana bullet works (so far).
