Edit: I should have noted earlier that my caliper was a bit off reading .3535 on the diameter of these bullets. I pulled my old Lyman dial caliper out and made some checks and adjusted the info below with the Lyman. Very little changed other than the COL is a hair over 1.140.
I've recently started reloading 357 Sig and of the all the cartridges I've reloaded, this one was, and continues to be, somewhat of a more challenging round to do mainly because of the short neck of the cartridge. Not that it's all that difficult but more specifically finding a bullet that I feel comfortable loading with. I've received a bunch of info from members of this board as usual and am thankful, but nothing too specific regarding which bullets work and which don't.
So, assuming any 357 Sig reloader already knows that any round nose NATO type bullet is out of the question, I'd like to share with you the bullets I have used and some information regarding them. Hopefully members here will be able to share the bullets that worked for them also.
Below is a picture of 6 loaded rounds using different bullets that I have fired. From left to right; Montana Gold 124gr JHP, Hornady 124gr JHP, Zero 115gr JHP, Remington 124gr JHP, Buffalo Bore (factory) 125gr JHP, and finally, Berry's 124gr FP. All of the rounds are seated to 1.140 with the exception of the Berry's, it is seated at 1.120. I did not measure the max diameter of the Berry's or the Buffalo Bore bullets but the others measured .355 on my caliper.
Here is some pertinent info that I thought might be useful to some of you, I tried getting it formatted to a table, but didn't have any luck so it's kind of busy info.
The MG124 bullet is .578 in total length, and measured .355 at point "A"
The HDY124 is .575 in length and measured .355 at point "A"
The Z115 is .531 in length and measured .353 at point "A"
The REM124 is .571 in length and measured .352 at point "A"
The BB125 measured .348 at point "A"
The BER124 measured .354 at point "A"
Anyway, what does it all indicate? Nothing other than there appears to be sufficient neck tension on all of these bullets to work in the 357 Sig. Interesting to note that the smallest diameter at point "A" is the factory Buffalo Bore.
Hope some of you find this worthwhile.
