Starline? Or don't they make the cartridges you want?

Have Lee make a custom seating stem for that bullet. It doesn't cost much. Ask them to have the seating stem NOT touch the meplate. Separate seating from crimping.

If the shots were at 100 yards, I would just say that I thought the basis for the ladder/OCW test was to place the target 300 yards and fire one shot at each charge weight and note where each shot lands. The location where the rounds cluster over some range of charge weights was then...

The basis for the OCW/ladder test is to determine the range of charges that will put the bullets into almost the same hole. In MOST cases, no, a 0.3gn charge weight variation will not make a difference. If you reshoot all three loads again, you may/probably will find that the "best" load this...

First, load some dummy rounds to determine the COL range that feeds and chambers. For rifles, I start with the longest COL that fits the magazine, feeds, and chambers (in fact, I do the same for handguns) and that is where I start load development as that is almost always where I get the best...

If you measure the bullet OAL, you will probably find the same variance as you getting for COL for the loaded cartridge. Tips vary all the time (inspect them and see how they vary—damage during processing and shipping). Ogives can vary depending on the swaging die used to create the bullet and...

Too bad you didn't measure all the rounds and see how consistent the COL was. I would contact DTAC and mention it. No, you won't get throat erosion to that extent that soon, not even with a .240 Weatherby Magnum, unless there is something seriously wrong with the metallurgy of the barrel.

1) Call the manufacturer and discuss the problem 2) Leave it on for at least 30 minutes. I leave my on continuously. 3) Does the weight vary depending on where the object is on the pan? If so, it needs service. now, I have been using digital scales since early in the '80s and never had the...

You will not find factory powder that is equivalent to a canister powder--it may be close, but not equivalent. One is made so that every # is as identical as possible. The other is made in huge volume to a much looser spec. and the factory tailors each lot to each cartridge. The powder...

COL: Cartridge Overall Length Have you compared the factory bullet to the purchased bullet? Do you KNOW that your reloading bullets are the SAME as the factory bullets? Bullets of the same make/type/PN are made in different swage dies and can vary. Manufacturers change bullet designs without...

Match loading? I use a powder measure. You? Whatever gives you more confidence. You're the one that has to "know" that your ammunition is the best. Unless someone does a double-blind study, they won't know what really improved their groups or if it was just their own confidence. See Hawthorne...

Have you simply tried SHOOTING and seeing if this slight difference is really as important as you making it out to be? Targets don't lie. Are you verifying that all the bullets have the exact same ogive curvature and the datum hits every bullet at the exact same spot compared to bullet tip and...

There is no single manual that can ever be best because NONE of them use the exact same lot numbers of components that you do, so you need to reference at least two sources, that use the same bullet weight and powder you want, so you can use the LOWEST STARTING LOAD for safety. Twice in my life...

The first throw with almost any powder (unless the weights are 4.0gn or less, in which case my machine doesn't really get out of trickle mode) will be about 1.0 over as it over-shoots. Every throw after that is x.x +0.1/-0.0gn--even Trail Boss. First, CALL RCBS. Guess what? There is a problem...

+1 Particular primers is no an issue unless you are shooting sub-½" groups and want to try to reduce it another 0.05" or so.
