Unusual Norma bullets

[c1a1]

I was given a box of 100 .257 dia. 160 grain bullets today. Was told it was a small run for a new cartridge Called .257 Condor, circa 1960. Does anyone reload for this round?

A 160 gr bullet in a 257 must be a very long bullet. I believe to would require a very fast twist to stabilize.

I shoot a 160 gr. Matrix VLD bullet in my 6.5 PRC that has a 1-7.5" twist barrel. The .257 is very close to the .264 in diameter. I would think the 1 in 7.5" would do it - and certainly a 1-7" twist would be enough. I will say that it may not make sense to work up a load for just 100 bullets that are no longer available. BTW - never heard of the 257 Condor.

Have you measured them?

I recall the 6.5mm was once referred to as .256".

Cheers.

This is the original story about the 257 Condor taken from GUNS MAGAZINE, Jan 1960 When a competent engineer decides to design a wildcat cartridge, some old ideas are given some new twists. The usual wildcatter reshapes an existing case, uses existing components, and the gunsmith chambers an...

Seems he could have saved a lot of time and money if he simply walked the bullet weights up per each barrel twist increment and he would have collected a lot more useful information.

Several problems with bullets that long.
Do you have room in your magazine?
If not it will take up room in the case that could be used for powder!
If you hang it out front you need a lot of free bore so its not jammed into the lands!
