So I was using Hodgdon Data tonight. I wanted to try the Cast Performance 425 gr. LFNGC as it's only 15 grains over the 410 gr. WFNGC bullets I've used before. The data was for a Beartooth Bullet 420 gr. with similar dimensions. Used IMR 4227, 19.5 grains which was the lowest amount Hodgdon listed. It looks like this bullet is slightly longer (about .03" deeper into the case). And it looks like the bullet slightly compresses the powder. I think it's okay, but wanted to get everyone's thoughts. Other factors are Starline Brass, CCI 350 primers, and a COL of 1.616" to 1.620". Some variance there.

So the component bullet is really only 5 grains heavier than the original bullet, I think you will be okay. Load a couple and see what the primers look like after firing, I think you'll be okay.

Ive loaded that exact same bullet with more than 1.5 gr more powder and not had a problem.

Rather than start a new thread, I thought updating this would be better. I finally have had some chances to try these at the range. Accuracy is excellent, and the chronograph shows an average of 1,066 fps. Plenty of power there and with the accuracy, this a good loading. The recoil is not soft, but is surprisingly reasonable when compared to other loads for .480 Ruger, .475 Linebaugh, .454 Casull, and .500 JRH. Comparable to a strong .44 magnum IMHO. Pretty pleasant shooting actually.
