what is an easy way to find the lands for the bullet? Is there a way to find them without a tool? I'm using Lapua 105 scenar bullets in a savage f class. all impute will be appreciated.

There are alot of ways to do it, and I consistently come back to this way:

Seat a bullet long into an unprimed, empty case.

Using a candle, place and turn the bullet briefly into the flame in such a way that you "smoke" the bullet uniformly with soot at the ojive.

Carefully, so not to disturb the soot, chamber the round and unchamber it.

Look for etching into the soot to show you the lands (equally spaced...)

I like to Re-soot and adjust the seating depth until I have satisfied that I have determined the seating depth for that bullet.

Remember...each bullet is different, and you'll need to repeat for different types...

Buy the right tool and don't fool around. For safety and other reasons you would be wise to get the right tool as many other solutions can be "penny wise and pound foolish".

We sold an AR-15 upper to a guy who wanted to use his "no tool" way to find the lands with a bullet. He would not buy a modified case from us for $7.50, nor the $30 tool it fits on. He loaded his ammo his way and spent a whole lot of money to take a special trip to go prarie dog hunting with a whole pile a ammo loaded up, and guess what, none of it would chamber because he loaded it way too long.

Don't go cheap here, get the right tool for the job.

We have an "Info Page" on our website that goes over this.

I cut down a casing so if you would look at it from the top it would be a plus sign or a X. Then just put a bullet in long and chamber it. The bullet will push back into the casing and will not stick provided you did not slam the bolt home. Do this a few times to get your measurement. You can do this with smoke or not. I usually put smoke on them and on a test round in an unmodified casing.

Then always double check your ammo and math. I found out the hard way by not keeping accurate data and using it. I was loading some 75gr BTHP in a 223. I took my measurements and set up my die. Did my load development for this bullet then tried a different bullet doing all the steps for the 75gr bullet. I shot all of my test ammo and then went home. I picked the best group to try again with the 75gr bullet. When I was readjusting the seating die I did not carefully enough look at my numbers and made the bullets too long. I refired that load and it shot great. Way better than before. I loaded up 100rds of this load and called it good. Well the next time I went shooting I had to remove a loaded round and well the bullet stuck in the barrel. A little cleaning rod action I was back in business. I ended up jamming the bullets in so far to the lands I could not unchamber some of the rounds. The bullets would pull out of some of the casings. I continued to shoot this ammo this day because there were no pressure signs.
After I got home I found out I had read my notes wrong and set my die to load the ammo long. I did not use the NASA method (double check and triple check) everything. This could have ended very poorly for me. My rifle could have blown on me or the ammo could have not chambered. I do always test my ammo in the temps I plan on shooting it so that is not an issue. I also usually never fire max pressure rounds if I had well…

This could happen to anyone with any tool. What numbers you put down can be read wrong or you can put them on paper wrong.

The best way is double check and triple check NASA method. Heck I have been reloading ammo since I have been ten possibly earlier. I am 33 now. I have loaded hundreds of thousands of rounds. Mistakes happen that is why you need to check and recheck.

I still shoot this jammed in load but I know someday it will bite me in the rear.
