Not only does a bullet jammed in the lands can cause accuracy problems it can put high dangerous pressure spikes into your gun. The way you do it here is the way I have done it for years. I was taught this way by Erik Cortina.
I didn’t say jam the bullet in the lands and live it there it up to you to back off the amount you want to jump It’s very simple no guessing once you’re in the lands that’s your max COAL
You reach the Leade before the lands. You want to find where the projectile touches the Leade and not the Lands. Touching the Lands gets you to the hard limit which is called, Jam. This will create extreme pressure and is to be avoided.
Only one problem. Sometimes the bullet will just ram into the rifling and not move if the neck tension is tight. I’ve had this issue. I had to make a cut on the neck to get the bullet to move
Yes that is quick version lol and i appreciate your comment , I simply meant that when you use your press to partially seat the bullet you just guess how far to partially seat it haha. I'm new to making videos so I'm working on being more clear and trying not to misspeak .
My sako 85 is 250 thou longer then recommended COL . Closest I can get to the lands is 150 thou. After that they won’t fit in the clip . So you can’t alway go with 20 thou off the lands in every gun.
Actually to my suprise, the base to ogive measurements are almost identical, only 2 thousandth difference with this method vs the modified case method in both rifles that I load to lands.
Just to clarify. You are finding jam not touch, it's two different points and ways of measuring. Your bullet starts to touch way before it jams. Either method works, but with this method you don't know if your loading into the lands or jumping the bullet, you only know how far off jam you are. Finding touch would be done with a modified case with no neck tension and a tool like the Hornady OAL gauge, pushing the bullet out until you just feel it touch. Using this method you will know if your into the lands or jumping the bullet. Like I said, either will work, your just looking for a reference point.
Nice video and thanks for sharing the information. I was a bit surprised to hear you say 20-30 thousandths off the lands, I’ve watched several other videos and read a few books , and I always thought that 5-10 thousandths off the lands was more of the benchmark for a sweet spot. Perhaps those were long range precision parameters for reloading, I’m not sure .
Yes, I have heard those same numbers, but mainly for competition shooters, in fact, loading to the lands in general is rarely done in a hunting rifle just simply do to the fact that in a factory rifle typically you cannot fit them in the magazine. I only really meant 20-30 for a starting point for your load development. I appreciate you watching my video and always appreciate comments from a fellow reloader!!!
@@hinshawshowto Hey thanks for the feedback ! I’m not really savvy just yet in reloading , so I was just inquiring about those numbers . I appreciate any information you can share . Just getting started into this mess and I recently picked up a new Tikka T3X Hunter chambered in 7mm-08 . So I have some learning curves to get through before I jump in both feet . I’m going to try to develop a good load for hunting elk within the limits of that cartridge. I’d like to load a 154 grain ELDX and get it somewhere up near 2,750 -2,800 fps. But I’m not sure about how far off the lands it should be for optimal performance and keeping away from too high in the pressures.
Yes it a fully prepared piece of brass ,fireformed,cleaned, sized, trimmed, just not primed. This way you know that each round is uniform and you don't have an anomaly in your dummy round that causes your lands measurement to be incorrect. I will note that your lands will change over time just from firing your rifle because the rifling will begin to smooth over time, how much depends on the rifle and caliber and many factors, so I do recommend repeating this process and tweaking your developed load if you start to see accuracy degrade over time. You may never have an issue. Or you might, just so your aware.
It would probably work on a lever gun but I doubt you could load to lands anyways on a lever action unless it was custom made, because i wouldnt think you would be able to chamber one loaded that long from the internal magazine on a production rifle
Very well done very clear and simple method. Without the usual complication shown by so many. Thank you

Simple to the point!
You reach the Leade before the lands. You want to find where the projectile touches the Leade and not the Lands. Touching the Lands gets you to the hard limit which is called, Jam. This will create extreme pressure and is to be avoided.
Also compare it to the magazine length. This might be nice to know but also pointless when you have a restrictive box size.

It’s simple you jam the bullet into the lands there is no guessing then it’s up to you how far you wanna be off
Yes that is quick version lol and i appreciate your comment , I simply meant that when you use your press to partially seat the bullet you just guess how far to partially seat it haha. I'm new to making videos so I'm working on being more clear and trying not to misspeak .
It’s best to remove the ejector also, just like when you use s headspace gauge
My sako 85 is 250 thou longer then recommended COL . Closest I can get to the lands is 150 thou. After that they won’t fit in the clip . So you can’t alway go with 20 thou off the lands in every gun.
Yeah, copy unless you wanna load one at a time, lol. Some guys do it, though!!!
Guessing that bullet has about 20 thou jam when doing it like that.

A little wax on the bullet and by hitting it open, the bullet won't get stuck.
I have never tried that, I appreciate the comment, that is very good info.

Is the dummy round fireformed and re sized before doing this way?
Yes it a fully prepared piece of brass ,fireformed,cleaned, sized, trimmed, just not primed.

Can this method be applyed to lever action?
It would probably work on a lever gun but I doubt you could load to lands anyways on a lever action unless it was custom made, because i wouldnt think you would be able to chamber one loaded that long from the internal magazine on a production rifle
And it's kind of a pain chamber loading one at a time on a lever gun
@@hinshawshowto Thank you very much for your answer!
If your resizing only puts that much tension on your bullet you have more problems than finding the lands .
