Weighing bullets,,,does it make a difference

Do you guys weigh bullets into groups and does it make any difference. I'm NOT looking for another step to go through during the loading process.
In one of the threads about loads for a 25-06 somebody mentioned weighing Speer TNT bullets that 400 would get him 200 good bullets.
When I built my 25-06 I was using once fired mixed lot military brass and Curry bullets and shot 5 shot 1/4 inch groups at 100yds.

I know the Barnes .338 225gr TTSX bullets aren't exact weight, they vary some. But I can put 3 touching at 300yds. Would sorting them make the groups better? ( each group would use bullets of exact weight )

Or are we talking about a needle in a haystack?
And don't forget about human error when trying to hold the gun steady and squeeze off those shots all in the exact same place.

I guess a rail mounted bench gun would tell the difference.
You guys shootin these 2 to 3 inch groups at 600 yds what are you doing/

Didn't think so BUT at longer rangers it looks to be the way to go

Hard for me to imagine bullets with enough weight variance to make any difference at all..

Re: Weighing bullets,,,does it make a difference

My experience is that weight difference corresponds to bearing surface difference when relates directly to variations in velocity.

I would suppose that sorting by bearing surface length would be more fruit full.

Then add meplat trimming and repointing and one begins to ask where the fun went.

I have a load in a 338 RUM that shoots lights out at 300 yds. However with its 50-60 FPS extreme velocity spread its pretty much useless for yotes and maybe even deer beyond 700 yds. My steel coyote, full size, was pretty save at 830 yds.

I've calculated, hopefully correctly that an ES over 15 with a high bc bullet will cause misses at yote @ 1000.

I don't do any of the above things. I used to when shooting benchrest but my LRH rifles out shoot any bench rest rifle I had. And I had some good ones.

Alot of BR guys weigh em but matches are won and lost on tenths of inches or less and extreme consistency is critical. I'd imagine some LR hunters sort and some don't, I don't.

Re: Weighing bullets,,,does it make a difference

if you want to sort bullets, sort by bearing surface not weight. The bearing surface affects pressure buildup inside the barrel (more surface, more pressure, more velocity). It goes pretty quick with a sorting tray and calipers with two comparators, attached closely to the base of the caliper blades.

After about 200 measurements I decided to quit sorting lapua 139 scenars. There was no variation to 3 places

I recently sorted couple boxes of swift scirrocos (150gr .284 and 130gr .264). On the 130's, 97 of 100 were within .001 and on the 150's, 97 of 100 were within .002. That is very good, I think I won't sort any more scirrocco's either.

I imagine it makes a difference.
