To sort or not....

posting thread/pic for Donald,


OK, You might say..... Here is a 3 shot group a buddy of mine shot last fall in a bullet testing session. He had been testing Fowler 66 grain FB, 65 grain Gentner FB and 68 Grain Cheek FB. At the end of testing he wondered what a 3 shot group would look like with each shot using a different bullet. All three shots used the same load, 28.5 grains 133 all seated with the same Johnson straignt line seater with no change in seating depth, which was moderate jam. Shooting conditions were good with wind so slight to barely move the flags. I no longer sort bullets. These were thru my Kreiger barrel. ....Don.

????????

I have the same question as Lou. What do you mean by "sorting" bullets??.
Considering the number of matches many of us shoot through the year, and how many rounds we fire, (thousands), I doubt I would base how I arrive at my combination based on one three shot group.
Maybe about a years worth of 5-shot, or even 10-shot, groups..........jackie
 
Hey Don... Ohhh Don...

Ring, ring goes the thread phone... Time to answer Lou and Jackie...Donald.:D

That Calfee fellow has got Jackie and I admit (myself and MANY others )perplexed about the 42yd dealing with muzzle stop and tuners or some WIERD PERFECT number Voodoo.........:confused::rolleyes::p

Guess, Don your simply stating that well three different bullets (Jacket length, Dies, weights) at 100 in ""exterior tunnel"" conditions "can" yield a one holer....:confused:....?

I did the same with my bullets off my Larry Blackmon 8 Ogive bullet dies...
Took a 62gr .790 jacketed bullet, 65gr .790 and a 68gr .825 jacketed bullet.
Same load 28.5gr VV133, though I did seat them to the same seating deapth inregards to the different jacket lengths (only the .825 jacketed bullet did I need to seat deeper....). Shot a .250 clover and yes, the 62gr pill went a tad higher than the 65 or 68...

Don, now here's a test, try three of the same bullets and three diff powders with equal weights.... OOOOOhhhhh say 133,322,Benchmark all at 29.0gr.... Same hole... I wouldn't bet on it!!!!!!!!:D

Lou, I must admit... I'm really interested in how successful the Hodgdon/IMR group is gonna be in duplicating T-powder.
Please keep us informed as the process goes on.:)


OK, Don............. Your turn.:D

OK, I Asked Cale to post this thread for me because I could not figure out how to get a pic attached to my post. Sort,.....as in sorting bullets. Some go to the trouble to sort by bearing length, some sort by weight, etc. Same as sorting cases by weight. I do what I am sure most do. When loading, I just grab one out of the box and seat it. I just thought it was interesting that 3 different bullets shot at essentially the same amount of verticle. Even though I had flags out I really wasn't paying much attention to them as it had been a long afternoon and I was tired and ready to pack up. And what is that 42 yard thing? I thought I had read everything posted about the "tuners and stopped barrel".

Good grief, what an over reaction. I was not testing anything as pertains to the target above. My testing was over. I just wondered how three different bullets would group using the same powder load. I just thought it was interesting that how close they were. :(

No Jackie, I did that twice, once at 50 and again at 60. Just starting my 70''s, don't think me or the old lady can take another one.:rolleyes: Donald
 
Here's a "keep the details away" comment:

If you have to sort bullets, you are using the wrong seating die.

But since I ain't Bill, here's my thinking:

What you're really interested in is bullet jam (or lack of it). Bullets with a longer ogive, if seated off the point of the bullet, will have a different relationship to the lands than those with a shorter ogive.

If you have a Wilson-type seater, you are probably OK with short-range bullets, they don't have an ogive that will let the die bottom out on the point. But if it does hit the point, open up the stem with a boring bar, so it makes contact with the bullet farther down. Now you "jam" will be pretty much the same.

Just one more reason "just touching" spits shots now & then.

The long-range guys guys sometimes offer a different explanation, e.g., variance in drag, but even if true, it sure won't affect the bullet enough to be significant at 100-300 yards.
 
I give up. I cry UNCLE. This was in no way a "test". I had been doing ladder tests on 3 different bullet and different loads for each bullet. At the end when I was ready to pack up and go home, I had 3 loads left. Each with the same powder and weight and each with a different bullet. I just wondered how a Fowler 66, a Gentner 65 and a Cheek 68 would group on one target. I was amazed at how close the impact point was with 3 different bullets, but with the same powder load. Do not read anything else into it. It might not happen again in a hundred years. I just thought it was interesting. Nothing of any importance, just someting interesting. Just forget that I even had Cale post it for me.
Donald:confused:
 
PMS.... Yep! Me too from time to time.....!

Ok Don, Now you say it wasn't a test.. Now explain....................!!! :D:p:p


Haaaaaaaaaaaaaa! Just RAZING YA !!! :D
