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

[Webster]

Most Tikka's, have, a HUGE amount of, "FreeBore" and they shoot well with,.. a LOT of Jump

Depends on what you call accuracy. Our definition and what world class shooters want is accuracy well beyond what we call very good. Erik Cortina says the rifles he shoots are designed to shoot zeros. Short range BR are trying to shoot 25 shot aggregates between .200" and about .230". One bad shot out of 25 puts you down the list.

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

+1
There is a danger that the take-away gets lost if we go down the semantics rabbit hole.
I didn’t find it difficult to follow what was being shown.

I hope more folks are willing to relate lessons learned or the sport will die.
YMMV

So, what dimensions are the sr benchresters rifles designed to shoot? Posted today.

This is why Cortina can be dangerous. He is intentionally misleading and guys that cant read between the lines get belly hooked into believing something that is deliberately being presented out of context.

Since he calls himself a "professional shooter" he attracts an undue amount of hero worship by newbs where they memorize something that has been misrepresented and it leads to 15 pages on this and other forums trying to find solid ground.

It's a video based on click bait like many others.

In the end, yes he is chasing the lands, just like everybody else.

Oh yeah, hes dangerous alright. Not sure how using his method is dangerous?

Its ok to disagree with peoples methods but go easy on the adjectives champion.

I'm trying something new on my latest FTR barrel. I have sorted 1500 bullets and bagged them into different lengths.

The barrel will start it's life with the shorter measured bullets and as time goes on I'll work into the longer and longer ones.

WHY? don't you just get a length measurement like the gentleman said, for everyone of your bullets, go to the range find the node for each and then as you shoot, you can just do like he says and load a few "long" and see if the node moved? That's what I'm gonna do.

Sure. I've done that, and it works. It's a lot easier than constantly tuning for the sake of tuning.

I'm trying something else that's absolutely no additional effort and seeing how it works out.

I'm with you! I just read one or several people on this forum telling people to seat the bullet against the lands (JAM) "oh don't worry as the barrel erodes it won't touch anymore" at least Mr. Cortina tries to keep one from blowing themselves up AND how you can get more the 300 rounds out of a barrel before "it's shot out"

Erik say's 1/4 MOA

 

[Webster]

Dude - it's not "hero worship". It's an appreciation of Eric's accomplishments and willingness to share with others what he has learned. It would not be a bad thing if more shooters displayed such traits, rather than railing against those with whom they may disagree.

The bottom line for anyone reading this thread or others like it is quite simple. There is almost always more than just one way to accomplish almost any step in a successful load development regimen. Do some testing to determine which method works best for you, and try to understand why a particular method works best in your hands.

Too much negative stuff on this website. People are fixed in there ideas and anyone that thinks different they insult or call stupid.

I’m on here quite a bit and don’t see that bad behavior much at all.

I also know seating depth is important, which is why in the video I talk about how I test seating depth for accuracy.
Only place we disagree is that I do not move my bullet out blindly without testing on target. And if I shoot on target and my gun is shooting as expected, but upon measuring lands it tells me I’m supposed to move, I don’t move. I trust the target more than I trust the lands movement.

I think most knowledgeable competitors already do this regardless of where they start their initial measurements or how often they measure touch.

 

[jvw2008]

^ and that may be your point: regardless how you start out: don’t chase the lands unless the target tells you to.

I don't know if this has been knocked around in these many pages, but to keep the same amount of "jam" in relation to the lands have any of you guys experimented with " soft-seating " the bullet, adjusting the amount of jam with neck tension. I know this would only really work with single feed shooting, but I would think if you got it working for you the only adjustment you would be making over time would be a powder tweak......I know you would be risking a chamber full of powder if you had to remove an unfired round.....

Your last sentence is exactly why I don’t mess with soft seating. Also, soft seating can often be affected by the amount of carbon, fire cracking and how clean/dirty the barrel is. Just not worth it to me. Better to find a solid load window that is at least .017” short of full jam.

I measure all of my Bullets and split them into bags with .001” max total length difference between them. I do believe sorting them helps but I don’t think that you will notice any improvement shooting them in any particular order, reason being is that the throat is eroding FAR faster than your bullets will be growing in length so eventually you will find yourself outside of the tube window and you’ll have load longer CBTO or shorter to find a different node. But I definitely agree with sorting Bullets by length. I have also found that sorting Berger hybrids, and certainly custom Bullets like Bart’s gungnirs, is almost becoming a waste of time because they are so consistent. For instance, I sorted a 500 box of Barts 105g Gungnirs and they sorted into only THREE bags with a max total spread of .001” in length within each bag.

How many times do we have to say that “against the lands” does NOT equal “JAM”???

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

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.

Depends on the discipline.......
