roll crimp or 6 fold

[charlie cleveland]

i was sitting here looking at somewinchester record brand 12 gauge shotgun shells...the first shell is a western superx 3 inch 12 ga maximum lubaloy load 1 3/8 ounce load this is a 6 point crimped load....2nd shell is a western record brand 3 inch magnum 1 5/8 ounce load it is roll crimped...3rd 3 inch peters deluxe load 1 5/8 ounce it is roll crimped...4th a 10 ga super x 2 7/8 inch shell it is roll crimped....5 th is awestern record shell 2 3/4 inch it is roll crimped....i was just wondering why they only put the 6 poinnt crimp on that one brand of shells and why they did not use it on the other line of shells... the shell they crimped was made in the early 1920 s for the new 3 inch long range guns it is not a magnum load yet..was the 6 point crimp better than the old roll crimp...i dont know thats what i would like to know....charlie
