Case trim length

[DMP]

How far under max length do you trim your cases?

0.010" on all my rifle calibers...

 

[ShtrRdy]

I do 0.005" short of max case length

Look at the SAAMI spec sheet

Look at the SAAMI spec sheet

Thanks
I know what the max length of my case. As the others replied, I wanted to see how close others trim to the max!

Same.

The sheet shows max and then -

Most reloading info gives a trim to length. Seems all of mine are 0.010 short of case max length.

 

[Deleted member 10043]

2.015 -.02

 

[Larry Jones]

Same here. 0.0005 short and trim or check every loading

 

[Snuby642]

Really 0.0005 short?
That's a typo or bullshit.

Try again.

 

[Snuby642]

0.ooo5 short of what?

 

[Deleted member 10043]

Anyhow, .01 because I hate trimming

The chances of SAAMI max and your chambers max being the same are slim to none.

I do 0.010 or 0.005 depending on the rifle/brass combination, except for hunting rounds which always get 0.010.

It's the fucking tolerance for that cartridge that is on the spec sheet and you are entirely correct. You may have a chamber +/- the Max. So what. If you're a little short you know how short you can go. But kudo on bringing up the obvious missing point.

The so what is if you have a long chamber and you trim to SAAMI max then you going to be coming up short on the lands with VLD's. If your loading for something that is prone to carbon rings then trimming too far under chamber max is going to make it worse and contribute to throat erosion. If you have a short chamber and go by SAAMI, you causing a who different shit show. Point being, SAAMI is great if the barrel was chambered to it, but most factor barrels play it safe because people don't trim their brass, and custom barrels get reamed based on the reamer the customer asked for.

As for bringing it up, would not have been an issue if you did not tell him to trim to the sheet.

I didn't tell him to trim to the sheet. I was pointing out not to trim further than that for whatever reason. You really don't need to write several paragraphs. I got your point the first time.

You trim to the middle or you suck.
