I start at max, then reduce by half a grain a few times.
Then I shoot them over a chronograph, starting with the lightest loads first.

Just curious.....so you do that first, then monkey with seating depths, or what? Who you callin’ a monkey? Racist bastard. P

Find desired velocity without pressure.

These threads are always so much fun!! Yes, it's got a lot of badly explained information. My only comment, for the record, on the initial subject is that COAL is pretty useless except to determine that a given bullet loaded for a particular rifle at a particular COAL will fit into a magazine. Assuming it fits a magazine, the only measurement that really matters at all is where a given bullet is from the lands when chambered. (As determined by whatever means you fell good about using, right wrong or indifferent.) Period. End of discussion. MM Fu ck an A right...
I try to stick with the basics, they do so well. Nothing fancy mind you, just plain jane will get it done with style. You want to see an animal drop right now? Shoot him in the ear hole. BSA MAGA

That's why it's very important to know where the lands are on your particular rifle, with every bullet you intend to load for that rifle. I think a lot of guys really miss that important aspect of hand loading.
It's a great example of what guys should be doing. Obviously he knows where the lands are on his rifle for this particular bullet. See where he points out ".02 jump" on the target. Great example there, where the OAL is listed as well as how far off the lands he's loading them...
Yep ! I determine the distance to the lands for EVERY rifle. Sometimes it’s too short to use the length OF the magazine. I had that in a 70 XTR FTWT 270 W. in 1982, early production. Sometimes the length is too long to fit IN the magazine. I’ve got that in more than 1 rifle. *The distance to the lands does NOT change*. The COAL can/does change due to length/shape of the bullet. -Generally- lighter bullets are shorter so they have to be seated farther out and STAY the same distance to the lands. The lighter monos are/can be the exception to that. These new long, sleek, lighter bullets ARE diff from standard c/c bullets. Jerry Good point Jerry..

Pharm, how did you know what powder charge to start with? JG & Pharm That load sounds familiar......maybe Mule Deer ? Jerry Yes, he provided input. IIRC it’s the max recommended load. ""I usually load a couple starting at max charge, and reduce by half a grain a few times. Then I run them over my Magnetospeed and look for velocity. Then I focus on the target velocity charge."" P My reloading manuals have always advised starting at a reduced load and working up half a grain at a time, while observing velocity with the chronograph, to arrive at the target velocity. If you start at max, and don't even check the velocity before reducing the load, how do you do this safely? Or did I misunderstand what you meant? . P You "start at max" then work down? Be honest, that was a piece of your Tikka blown to bits in the other thread wasn't it...?

I’m constrained by magazine length for my Tikkas in long action cartridges, so distance to the lands is meaningless. I start at max magazine length and then go backward.

Good point Jerry.. Hey, somebody can read & comprehend English, wow ! whatdayaknow !! Thanks BSA, I used the most clear laymen's terms to describe Distance to Lands AND COAL or OAL. Some people have problems with it. Thnx Again Jerry

I would like to ask if say I am using Sierra 243 bullets in either a 243 or 6mm would bullets of different weights with the same ogives would give the best accuracy with the same COL? If I am shooting a 6mm and using a 2.860COL (Best accuracy) for the 75HP would a 80SPBT and a 85HPBT (They all have the same ogives) give the best accuracy after you found the best powder charge for each bullet give the best accuracy with a 2.860COL also?
Good Shooting,
George

In my experience, probably not, but not always. And if it does, it could be just luck. One time when COAL can be useful is if you find a factory load that is very accurate in your rifle. If you load the same exact bullet to the same COAL, (producing the same jump to lands), in my experience, it is usually very accurate, also. This can save some time in load workup.
