Am I out of my mind?

[jackson1]

Getting ready for my first 600 yard benchrest season. Got 200 cases prepped and fire formed (6BRA), did some early load testing, and am attempting to master the art of getting my powder charges correct to the second decimal place. My cases are trimmed to within 0.0005" in length with a precise chamfer. Not complaining, as far as I am concerned, I think this is just part of the game. I am waiting on my Vaportrail bullet order so I am using another match bullet. Getting bullet bearing surface length differences of 0.004" from long to short and a weight difference of over 0.1 grain in weight. Don't even ask about primer weight differences. Starting to wonder how I ever hit anything in my past shooting life. Can anyone tell me if my loading practices are out of line, similar to others, or par for the course. Thinking now that I should have purchased a couple of extra barrels. Hopefully I'm learning.

Well what you are doing want hurt any thing does it help I know some guy's that say's it not worth doing but who knows it kinda like barrels some shoot everything good and some don't but I have had some barrels that shot great once you got the load wright

It's relatively easy to achieve 1/2-MOA at 600-yards. But it takes another level of detail to achieve .3-MOA. And even more detail yet to get to .2-MOA. Plus to be able to do it consistently is another demand itself.

To win and repeatedly finish strong in LR benchrest, little can be taken for granted, where diligence in each component and reloading aspect contribute to creating perfect ammo, which is the demand.

...I know some guy's that say's it not worth doing...

Read those inputs all the time, but rarely from LR-Benchrest shooters that compete at a National level.

I have no idea, I’m in same place you are, going to shoot my first long range br match this year as well. Hopefully we both will learn something at a few matches. Good luck Troy

i have changed my mind, esp for long range shooting.
several long range shooters do claim less vertical with sorted primers.
one more task for the loading bench!

you get what you pay for...you paid nothing

you cannot weight sort primers
4 parts
anvil probably close but you do not know
cup who knows how close they are
sealant..no idea how much or how uniform
priming compound....the only thing that really counts
and you have no way to weigh it separately from the other 3.
even if you ASSume that cup and anvil are "uniform" sealant is not.

Do you not recommend sorting primers then? Or what's your method ?

 

[DanSavage]

I wouldn't bother messing around with the primers but I would weight sort the brass heaviest to lightest and stick to a good consistent annealing regime. Definitely on the right track for great results man.

Using a good priming tool like a 21st century adjustable goes way farther than weight sorting in the priming dept. just shoving them in there with a lee or rcbs tray tool while convenient isnt very conducive to accuracy.

uniform the pockets and after firing
seat primers to the bottom of the pocket and add a small crush fit..aprox .002"
uniform ignition requires the primer to be in the same place and to not move.
if you seat to 0.00x depth and the pocket is deeper
the primers move on every shot..not uniform

You seat them till they touch ........ in a uniformed primer pocket with reamed flash hole. .002 crush sounds like the days of the click bang Wolf primers..... jim

Using Lapua brass. Recently purchased a 21st Century priming tool and primer pocket uniformer, as my other equipment was not up the desired standard of precision. I really enjoy the precision aspect of this sport. Just do not want leave any stone unturned, but you don't know what you don't know.--If i wasn't so old, I would get a tattoo with that statement on it.

Primer weighing was a suggestion from another shooter I know and yesterday I tried it.
Going to sort my bullets by weight and bearing surface. For brass I weigh them and sort, and cull any unexplained fliers. Thanks again for your suggestions.

Know quite a few who will disagree with you....lol
Myself will never go to a match with out having done so.

I do all the standard treatments to the brass. I was just surprised that you dont find it useful to sort primers by weight.

Im tracking down an issue I have with small fliers, and it turned out to be an issue I caused with the brass. However I did try two 5 shot groups at 200, one with all things sorted aside from primers, and my standard loaded round, and found the unsorted group to have some mild fliers. I think Ill keep sorting by weight. I just wasnt sure if you had another method to sort primers.

This kinda confirms my suspicions that I am not the only one sorting primers.

I use Wolf SRM primers in my comp. 6mmbr load. You MUST seat them deep. Or no ban. Tommy Mc

You just took something fun and made it into work.

 

[retired]

not really.
some of us actually LIKE loading, and the various tasks that go with it.
the advantage of being retired.

i sorted 1000 lrm primers and 1500 sr primers last week.

There is a sub culture in modern shooting that worships the idea that doing ammo prep in reloading more ALWAYS improves accuracy. To the point that the most obsessive competitors MUST be winning because their equipment is superior due to their obsessive nature of their personalities.

I believe this is a lie...

just for chits and giggles,
how many national championships do you have ?
just trying to sort the wheat from the chaff.

The ultimate Internet troll move is too elevate the conversation to the level that only a "national champion" is worthy to comment on any discussion. It is almost like Jim Jones cult... Completely Unamerican in it's nature and elitist.

Long walks and short piers comes to mind.
