Ben Diss Posted August 26, 2011 Share Posted August 26, 2011 I took a chance and ordered some of Brownell's new Colorado 128 grain .357 RNFP bullets. I figured I'd check a few and see how consistent they weigh. Not good. They're all over the place, from 119 grains to 134 grains. Seems like most are around 132 so I sorted them and kept anything between 131.00 and 133.99. That yielded about 50% of the 500 ct box. What weight range is acceptable? Is a +/- 1 grain spread close enough to still get good accuracy at 25 yards? BTW, I also ordered a box of their 158 round nose and these all weighed within +/- 0.5 grain of 162.

anachronism Posted August 26, 2011 Share Posted August 26, 2011 That's quite a variance, about 12%. At such short distances, you probably wouldn't have a problem. Try a few magazines of mixed weight reloads at the distances you shoot and see if you can notice the difference. That's probably the best indicator.

Ben Diss Posted August 27, 2011 Author Share Posted August 27, 2011 I hear what you're saying, but I like having confidence in my equipment so that I know if I miss, it's me and not an errant bullet. Still, I'll load a few from the lot and see if I can tell any difference. Link to comment Share on other sites More sharing options...
