Seating into the lands...cant measure!

[Bill Norris]

There are just so many ways to make something simple hard. Forget jam, think touch. Its only a reference point.

Much easier to simply find touch and go either way you like.

I might have missed it, but make sure you aside the brass and bullet if you’re trying to track erosion. Using different brass and bullet may screw with your measurements a few thousandths.

leaves bullet in rifling & powder in the action.

I've had one (1) barrel that shot best when the bullet was seated a couple thousands longer than touch. Had a cease fire in Raton one afternoon and jammed things up. Varget and lugs don't work very slick. Started carrying a long nose lighter, can of air and a chamber swab in my range bag. I used it one time, blew all the powder out I could and hit it with the lighter. Small poof and a swab later, I was back in action. Yeah, got a weird look from the guy keeping score for me but I didn't have a DNF like Raton.

All I can say is why..go to all this trouble.?....Juice aint worth the squezze for me.

Depends, I never jam or chase lands with conventional but the solids I shoot like close intimacy with the lands.

A modified case that I can screw a cleaning rod into and a method like DLT is what I use if I’m being lazy and don’t pull the barrel.

I have never shot anything jammed for long. Touching yes. Black Sharpie on bullet. As soon as I see the faintest of land marks that's my touch point, which is just a reference point for Me.

The world is changing. 10 years ago if you didn’t have a square mark from the lands and .002 neck clearance you were a buffoon.

Now, a short jump and a little clearance is considered a good thing by many.

I just spec’d a reamer for Peterson 6 GT brass that would have made 2010 me laugh. Live and learn.

I've been adding clearance to the freebore and neck for a long time.

If you use the Search function.....Seat in the lands.....you can read for a Looooong time. Just a thought.

If you're looking for actual jam point Erik's video makes the process super easy to find it. I shoot in the lands all the time now so knowing jam matters for me.

Why would you need to keep taking the barrel off? If you have a seating depth that is working for you and you fire a bunch of rounds and it still shoots good, do nothing. If it stops shooting you need to test seating depth again and you are going to seat it longer. It may or may not be a 1:1 relationship. If you pull the barrel and determine it moved .005, that doesn't mean its going to be back in tune if you seat it .005. it might be, or it might be .003 or .007 that you need to move. Therefore, no need to measure again and make assumptions based on that, just test it.

wheeler method works, and will repeat results accurately every time

 

[pavementends]

After finding your "touch" measurement and writing it down for future reference, how many rounds do you fire before looking for "touch" again? I would think it would depend on what you were shooting. 28 Nosler vs. 6BR

 

[quest450]

every time you load for the next match

 

[Idaho-Lefty]

After much Research ( HERE ) I found that, the 107 grain, 6mm SMK's, Like to Be, Jammed .012 to .015 into the Lands,.. PAST,.. "Touch" point, in my, 6 XC, the Group's,.. SHRUNK by,.. 40-50 Percent !
And, I ain't, going Back to, "Jumping" the SMK's,.. in THIS Rifle !
I'll re-Test for the "Touch Point" every couple Hundred Shots, as the 6XC, AIN'T,.. a "Barrel Burner"

It’s really hard to put a number on that but for a 22 Creedmoor or 26 Nosler it might be 60 rounds.

For a 6BR I’d at least check it every 250 but I doubt it moves much and I sure wouldn’t move the bullet up unless the gun isn’t shooting like it was.

I’ve got one that’s still shooting like it’s brand new and I have not bumped it in 600 rounds. It doesn’t even show to have moved. I keep the original bullet that I found with lands with, and I think you should too!

I found years ago I could pull loaded rounds using .006" into the lands. I have used that as my basis for loading ever since. I test every two tenths gn of powder from say 33.0 GN to 35.0 gn and hope to find a nice node under .100" 3 shot groups. I also went to using a .002' mandrill in my loading process which holds .006" in bullets. Guns shoot great this way. I check and adjust every loaded round for an exact OAL using a comparator on a dial Vernier. Works well for me.
