I have a Lyman case trimmer that’s giving me
A 0.001” -0.002 “ tolerance ie last night i was trimming some 6.5 Grendel brass to 1.520” and i was getting anywhere from1.518 - 1.522 but most were within 0.001
Is that acceptable ? What could i be doing wrong?
What are you measuring that with?
A cheap set of digital calibers maybe they are the issue?
If your trimming to book spec and are not chasing a f-class title don't worry about.
What bully said.
If you put pressure on the handle while trurning you can make the trimmer flex try screwing the trimmer to a solid peice of wood
that help mine with mine, a nice 6"x2" works well
yes thats fine..only thing wrong is overthinking it...you are talking 4 thou max after all.
Well I just loaded 50 up
The new lapua brass Done 0.334” @100 with 32.3gn of cfe223 pushing a 100gn serria hp loaded to 2.200”
Let’s see how it goes with once fired brass hopefully the same if not better put new glass on the rifle last week also Nikon Monarch 4-16x50 so I need to zero that also
I have never measured my case length, if the lee trimmer takes some off good, if not good :) Slack aye
I'm like Gibo.
Only issue with the Lee trimmer is when I built a 6.5 Grendel and then discovered they don't make a gauge for it. A custom one was going to cost over $60 US plus postage.
So got a 7.62x39 gauge for $12 NZ and turned it down in the power drill to 6.30mm or so.
Gibo...they work a treat...once you learn to use the base piece..they tend to keep cutting if you dont as I found out when first got it LOL.
Yep you need the base as that’s what the cutter bottoms out on
Found that out the hard way 2
I have one and still use it with one case I then put that trimed case into the Lyman and
Push the cutter up against it as a quick and easy way to set trim length
I don’t like using a drill with the lee cutter as I find it cuts quite rough and requires alot of tidying up with the chamfer tool
So I cut the single case by hand than use the Lyman from there on
