Beveled base bullets

Post by mike herth »

What is the purpose of the bevel? Eliminates need to slightly flare the case mouth? Any effects on accuracy? Is anyone using BACO’s Postel bullet with beveled base?

The description on Bacos website explains the bevel.

Last time I loaded some paper patched bullets with a real sharp base into brass that was pretty snug, I was thinking a slight bevel or rounded base wouldn't be so bad. I wouldn't tear so many patches.

Not sure what it would do to accuracy.

The Baco bullet shoots well in the 45-70
But the very few I shot in the 45-90 it wasn’t very impressive

Well, I may have to try that BACO mold and follow Semtav into the dark side…

BA says to reduce finning. Magma engineering used bevel base molds with all their casting machines to help the bullets ease from the mold cavities. Man that would be the deal, big ole greaser ever 15 seconds or so with the crank of the handle. Hmmm.

Mike Herth, actually I have two separate more or less one off, at the beginning, moulds on my bench from Jim Brannon at BACO.
One is a copy of the original Ideal 456132 which is bevel based you are inquiring about. The idea was/is to evaluate both for Long Range.

The original Ideal 456132 was apparently created toward the end of the Creedmoor era in the 1800's and available on special order until the 1970's from Lyman. Samples from an original Lyman Mould were sent to BACO to cut a duplicate mould. Why the bevel base is subject to speculation that, on this forum, by consensus finally might conclude that the bullet was intended for later field artillery uses so I won't go there.

The logistic problem continued, seeming indefinitely, due to heavy equipment activity on all ranges at Tucson Rifle Club right up until I left for Phoenix March 22nd. Lamentable situation to say the least.

So, while both have been through initial scrutiny on paper and steel at mid range distances, long range evaluation has not been possible. (The second one off was hugely impressive in ladder load development at 200 yards.)

With that said, ("INITIAL"), results with both are encouraging at the powder burn distances normally available on a silhouette range which, by experience, do not always agree with results from 800 yards and beyond.

At present the probability that both bullets will be shot in both 16 & 18 twist rifles with 1-16 alloy is high.
