Will52100,
After fiddling with the link you provided managed to come up with a part number of DD-500MkII for a .45 Caliber bullet with two very wide grease grooves and a very pointed nose.
www.biglube.comFirst knee jerk reaction to this bullet design would be that the pointy nose will detract from the desired outcome of/for distance shooting.
The Lyman Spire Pointed 459658CV is seldom seen on Black Powder Cartridge Rifle Silhouette ranges. After having purchased this Lyman 459658CV mould and utilized the cast bullets from it, the end result is far outdistanced by cast bullets from Lyman mould 459132CV which basically repllicate the nose cone of a NASA Liftoff rocket.
The bullet designs that seem to be working the best are either round nosed or NASA nose cone designs. The Lyman .45 caliber Postell and the Lyman .40 caliber Snover for .40 caliber cast bullets are both great starting points in bullet designs. The old Government Round Nose bullet is also a great performer in .45 caliber.
No free rides when it comes to bullet designs. Pointed design bullets are great for high speed smokeless loads, but seldom make the transistion to the lower fps velocities of our BPC Rifles.
Simple way to look at big bullets and how well they are liable to perform at our utilized velocities ........... think NASA nose cone design!
Hope this is of some help..
