So i typically start at min ladder up to max in 1gr increments. See what is the tightest between 2 charges and then bump up .3gr increments between the two. If nothing is satisfactory. depending on what showed promise, low end or high end i move to that range oustide of min/max by .3gr

First step figure out where the bullet your loading likes to be seated in relation to the lands and then load from mid range up to max in .3 gr. increments and shoot.

I don't guns with large case capacities so my ladders are always .3 grains apart and I use a ladder. To me 1 grain is to big of a window for me to work in...example on a 6br 30 grains is fine but 31 and I could have a huge mess on my hands.

Only time I don't use a ladder is I know a specific range I'll end up in and I just work within that range.

Oh and I always shoot my ladders .010 jammed. I want to know where pressure is and look for nodes. So then when I back of the lands I'm actually lowering pressure (I know there is a point where I could build back up because I'm decreasing case capacity but I don't normally jump stuff that far).

When trying out an unfamiliar combination of components, I'll go through what I call pressure trials to see what I can determine to be a safe range of powder charges. I load two of each charge and shoot them over a chronograph. I use QL and published data to evaluate pressure, and watch for pressure signs too. If velocity begins to climb beyond what I think indicates safe pressures, I won't fire any of the higher charges. As I'm doing this I watch for signs of a load wanting to shoot---or maybe its better to say I watch for charges that DON'T want to shoot.

I usually see a charge or two that show some promise, so my next step is three or five round groups. If all goes well and a particular charge stands out, then I'll fiddle with seating depth. I usually start out about a tenth of a caliber off the lands, but by the time I've come this far I'll usually vary seating depth in 0.005" increments down to 0.003" increments, depending on bullet diameter.

Find out "the" powder for the bullet I am running in a specific cartridge. This site is a good place to pick people's brains.

Find the rifling, and seat the bullet even with the lands. Check that the cartridge fits in the Mag. If it won't then I'm bound by Mag length.

Short action cartridges:

Research Hodgdon's max, as well as two books. Go with the highest max. I back off from Max in .3 gr increments looking for around 9-12 rounds. Shoot the ladder, shoot groups of the charges within the node. I like 500 yards better than 300 yards when it is a custom rifle.

Long action I do the same thing, start at max and back off, but in .4 gr increments.

If you give me a new rifle, same barrel length, with a cartridge and bullet combination I have loaded for I will skip the ladder test and go straight to group shooting. 6.5 Crredmoor, for instance, I'm going to shoot a 140 gr, H-4350, and load between 41.8 gr and 42.8 gr. Give me any .308 Win shooting a 175 SMK or 178 A-Max and H-Varget and I will group shoot 43.5 gr to 45.0 gr.

Chad doesn't ladder test because he is a walking loading manual. He can go straight to groups because he know about where they will shoot for a huge list of cartridges.

My approach, over the last 35 years or so, has been modified several times. So, these days, if one of you nice fellows gave me a new 243, which I don't now load for, I'd do a little research on best powder, which would include asking ya'll about it and checking manuals. I'd probably shoot a Nosler BT or Sierra GK, so I'd pick the one - probably 100 grains. I'd probably get some Norma or Lapua brass. I'd work up loads from about midpoint, rather than the minimum, and load them to factory COAL. I would pay close attention to what the Nosler book says is the most accurate powder charge, since their suggested loads for my other rifles are almost exactly what I have found to be my most accurate loads (can't be a coincidence). I'd progress in .3 gr increases and shoot 3 shot groups till I found the ones that look good and then I'd go to 5 shot groups. I'd clean the barrel often during work up unless I found that it didn't foul badly. I won't assume that a barrel doesn't foul.

Once I find what I think is my load, I'll wait till the next morning and shoot a 3 shot group from a cold bore, and I might shoot more than 3. And then, I'll fiddle with COAL.

I didn't fiddle with COAL for the 260, since I didn't really think that trying for a smaller one hole group was worth the effort. I'm still at factory COAL, whereas for the 223, 220, and 270 I'm closer to the lands.

Might I suggest, sir.

Book C.O.A.L. is elementary school. Join us in high school, get some bullet comparators, try the cut neck method we have talked about so many times, and learn where the rifling is in your chamber. Not knowing where your rifling is and using SAAMI specs means you could be handicapping your self some.

Just a suggestion.

It depends on the rifle and what its intended purpose is going to be. For my long range rig I decided that I only want to single feed it so I don't worry about mag length. I'm actually approx 1/3 of a inch longer then the mag box for it. But before that I pick the bullet, and brass I want to use. Then I pick the powder and primer. After this I check my chamber using a OAL guage and bullet comparators, followed by several groups in either .5 or .3 grain increments usually starting at 1/2-2/3 max load, working my way up to max load. Once I get a group that I like how its shooting, I check it for ES and SD with my chronograph, and if need be play with seating depth lastly.
Thats a short version of it anyways.

Fireman, if you are talking to me, try to not be so patronizing. It's offensive and unwarranted.

I started the post with a "sir"

Was trying to add some humor in the middle.

And ended it with a "just a suggestion"

I can't get any nicer than that. I will keep it all to myself when it pertains to you, if my gentlest attempt is still offensive.

Carry on.

Most accurate was always my goal. I started at the min. in the loading book and worked up in .3 gr. increments. I seldom got to the max before I found the most accurate. Groups would get smaller as I worked up the ladder and then would open up as some point. Once I found the most accurate I would then work up and down a bit to fine tune.

You weren't trying to be nice and you weren't funny. Just plain rude, and you know it. I notice that you get that way sometimes when you talk down to us ignorant mortals when we diverge from the approved 'fireman' method.

Measure chamber and setup sizing die to seat bullet .015 off.

Than i look on the interweb for what seems to be the most popular load for the bullet I want to seat and powder I want to use.

Then I use that.

It means I usually just copy what someone else's best load was and use that.

That and my last 3 barrels have been the same caliber.

After 600 or so rounds I'll re-measure the chamber and reset the seating die to get the bullet back where I want and maybe add 1/10 grain.

With a barrel that has a useful life of around 1000-1500 rounds I'm not gonna waste a whole bunch on load workup.

I hate load work up and I hate reloading.
