Chasing the lands is stupid... What do you think?

[Dave M.]

Depends on the discipline.......

Agree, in BR is probably a must.

I found the same thing last weekend when I sorted 250 142gr EPS .003" total

That’s good info on the EPS bullets. Thanks

It’s daunting to say the least and when you only end up with three bags and a .003” total spread it almost seems pointless.

I did find 1 outlier that was shorter than the rest.
Its going down range 1st. Lol

So it was worth while then…that one could have easily been an “8” at 1000 yards.

Shit brother i can roll a hard 8 at 300 yards. Lol
I feel it was worthwhile to find the 1 outlier to use as a fouler all while talking tuning with @SPJ at the same time.

It might have stayed inside the group too. I don’t recall sorting these bullets but they sure stuck together.

Chasing the lands is stupid. Bottom line Eric's title is just to generate click traffic for his website (YouTube).​

pure Marketing.

It can be. But I don't know many people that did it that way or do it that way.

Erik's data appears to be in respect to the "lands"

The freebore is the section in front of the chamber where the lands have been cut away to make room for the bullet.

In front of this is the leade which is an angular cut into the lands that ramps the bullet into the rifling.

What we are measuring in a new barrel is where the ogive on the bullet contacts the lands in the leade where resistance is met.

This is the start point.

Erik's data appears to be in respect to this point.

He started 2 thousands jump off this point tell he finds a seating depth that shoots well. He then takes it further and documented the length of the node and seats accordingly to stay in the node as long as possible.

As throat erosion takes place from the lands being vaporized due to combustion. He has to compensate for this and adjust seating depth and seats the bullets longer. We called this chasing the lands.

Why did he have to adjust seating depth?
His node moved.
Why did his node move?
Combustion caused the lands to "move" as a section of them were vaporized.
He adjusts seating depth to compensate.

This is Chasing the lands.

Semantics. Stupid that people are arguing over verbage. Still a good informative video.

Of course he is chasing the lands, but look at all the attention his Click-Bait title has accrued to him. Not quite in the Amber Heard league, but still …….

Correct. I only find "jam" so that I stay away from it. If I am limited by mag length, then I don't care where jam is ever. All I worry about is where the rifle shoots.

For example: "Erik, where do you seat your bullets in relation to the lands?"
Me: "I don't know, however, I know my rifle shoots well at 2.150, 2.153, and 2.156, so I seat at 2.155"

Click, I love it..

There is hard Jam, and then the real Jam.
