I'm new to reloading so bear with me please:D. so I bought some winchester 125 gr. FMJ bullets, with a bullet diam of .356 and 1lb of Hadgdon HS-6 powder. I can't seem find any info for reloading 125 gr. I went to the Hodgdon relaoding data centre and I could only find info for 124gr. FMJ diam .355.

So I'm wondering if I can still use those loads with my bullets or not. If not, where can I find info :confused:
 
if you have a chrono yes you can. start with minimum load and watch for pressure signs. the 1000th of an inch will increase pressure slightly. the 1 grain bullet weight will make a minuscule difference.
 
Use the data for 124 grain .355 bullets and follow normal work up procedures. I'd be really surprised if the extra grain or .001 made any difference. Most handgun bullets will vary in weight by a grain or two, and diameter can be +/- .002 or more.

Out of curiosity, are you getting .356 from your calipers or from the manufacturer's description?
 
Another important question that I am a little surprised that noone has asked yet is are they a true jacketed bullet or copper plated type ? Loading data for the two are slightly different the plated load closer to cast specs.
