Who does not trim their brass?

I reloaded 22-250 at least 5+ times in the past without trimming, the length was good too, using hornady brass. Sometimes it doesn’t steetch.
Yeah I can get a few rounds out before having to trim too. All depends on how short I initially trim them. I have about 600 cases so I try and rotate. 22-250 definitely doesnt stretch as bad as I heard before I bought. Cheers
 
You can buy the little caliber specific plugs to check your actual maximum brass length. Most of the "maximum brass length" SAAMI numbers are much shorter than what a chamber allows.

I think they may be made by Stoney Point, but I can't recall off the top of my head, sorry!
Sinclair Intl chamber length gauge is what they're called

Work very well to identify your chambers actual max length. On the dozen or more rifles I have measured, they're usually .030" longer than max case length.

If anyone knows where you can get these in Canada in 6mm and 7mm I'd love to know!
 
This is exactly what I am seeing hence the post, the thinking is if there is less distance between case mouth and chamber, there will be less carbon ring to clean out. Very clean chamber BTW, what do you use?
Wipeout and JB’s, and elbow grease.

That literally the barrel fresh from the gunsmith…….. before shot 1
 
No need to trim this 280 Remington brass. This is an extremely accurate rifle, but I need to get the carbon ring compltely gone the next time I clean it.
You can see the gap between the ring and the end of the brass case

On my match rifles I haven't teally noticed that much stretch

Likely because you have a very tight chamber in that rifle, and you "neck" or "partial" resize only.

The less the brass case gets "worked'' or full length resized the less stretching, if any is to be seen.

If you're really fussy about accuracy, you would check case neck length every time to make sure they are all within .002 of each other.

Some folks believe this makes a difference in POI from round to round when you're aiming for a tiny dot or center X.

I had one rifle that it did make a difference if the lengths went out of the .002 limit.

Most rifles will easily handle .005 differences and hunting rifles more.

It's sometimes just something else for hand loaders who shoot match rifles to be anal about.

I make sure my cases are uniform just for procedure'ssake , yes
Even my hunting riflrs have custom made barrels on them fir the most part.
However, I do not shoot bench rest matches but TR, my style of match shooting realies more on shooter ability than if a cases is
002 or .0010 longer than the other
 
Doesn't matter how "good your ability" is, if you have an inconsistency creating an accuracy issue.

The issue may or may not happen in your custom cut chambers with a few thou neck length difference, but some folks think it makes the difference between winning and losing.
