Questions regarding loading to mag length

[fireroad]

In my haste to find the perfect load for a newer rifle I plan on long range shooting with, I made a rookie mistake and designed/tested loads based on distance from the lands and not magazine ID. When developing loads for a cartridge that is the same length as your action (SA cartridge in a SA action) is there a specific method that folks follow? I'm assuming that there is some rule of thumb for difference between mag ID and max coal, increments of COAL or ogive to test...or am I making this too complicated and just load to the max COAL that will work in the mag and instead work with different bullet/powder/primer combo's to increase accuracy? Thanks in advance.

Rifle is a Rem700 LSS, 243 win, SGK HPBT 85 gr, RP brass, BR2 primers, and several powders (working on H414 right now)

Depends on whether you plan to use the rifle as a repeater or a single shot. The coal of the round is dictated by the mag length if you want to use it as a repeater. As a single shot, you can load to any length that safely shoots in your rifle.

It's going to be a repeater.....

Load as long as you can and have them still feed reliably. Then try different bullets, powder and charge weights to get the best accuracy.

I have all my notes packed as I am moving or I could tell you how much mag clearance I use and still get acceptable feeding. I think about .025" maybe?
