Default Pb 45 Caliber 545g

52Bore (Rick) made/sent these bullets. Rick added the plug to create the hollow point.

The distance between the rifle and horse is 25 yard. Powder charge is 50 grain Blackhorn.

The bullet can be seen in the fifth bottle. The sixth bottle is undamaged.

After reading the title line, was expecting a test of a new monster-sized Powerbelt.

Due to the bullet length, I'd expect major keyholing at 100 yards, using more powder.... like 80gr BH in a 45-cal barrel. But then-again,maybe not! I experienced my keyholing when using a real long 260gr PR sabot/bullet and this pictured conical fit the bore wall-to-wall better.
So I haven't any experience judging these real long conicals with heavier powder charges than a kid's prescribed 50gr.

.Anyone here tried a conical this long at 100 yards, with even 70gr BH equivalent and didn't suffer keyholing-effects?

Sure no problem at all in a 1-24 or faster twist. Really more like 1-20 or faster for one that long. Ed's 465gr shoots fine in my Super DISC with BH209.

A 1.375" long bullet has little chance of shooting well in a 1-28 though. Run it through JBM and see for yourself. It would be VERY unlikely.

I don't think I'd even attempt shooting this in my 1:30 GM barrel. Anyway I'm perfectly happy with my 370 gr 11 mm bullet. (Thanks Ron)

This bullet has set a few records at Friendship, most notably at 200 yards with multiple 100-5x in the AGG.. 1:20 & 1:18 twist barrels. MV around 1300 fps.
Diameter, twist, length and weight of these size bullet is nothing new, it was done in the mid-1800's. This one just has an added HP.
