Some what confused

What is the point to going to the trouble of measuring distance to the lands when I have to seat my bullets to factory specs for the OAL in order for them to cycle in my rifle's magazine. Nosler gives the OAL for the 300 saum at 2.825 (this is a head to tip measurement) and that is the longest I can seat my bullets and them still clear my magazine. To the lands in this rifle using Nosler 180gr AccuBonds is 2.9915 but I have to seat the bullets to no longer than 2.825 or they won't clear the magazine and will not cycle through the gun properly. It was the same way when I was reloading 180gr Scirocco 2. In order to seat just off the lands or even close to the lands I would have to shoot the rifle as a single shot

sjadventures,

I think you have it figured out.

There is no sense in the extra effort when the magazine limits the overall length.

However, some bullets like to jump more than others. For example I've had better luck jumping Hornady bullets, interbonds, than some others.

Correct, if you are going to use your magazine and don't have a Wyatts box installed so you you can seat the bullets further out you don't need to waste your time measuring the distance to the rifling.

My 300SAUM really likes 61.7 grains of H4350 with Federal 210 primers 180 grain TSX loaded to magazine length (2.82")

correct length

As pointed out, you have indeed figured out the correct length of the loaded cartidge and indpendent of the bore length. Some rifles have a lot of free bore (weatherbys) but still it has to clear he magazine. If you think about it, makes sense.

Remember, barrels are harmonic devices just like tuning forks. There will be more than one "sweet spot" or accuracy node. On magazine length limited guns, I have found that there may be as many as four node options. Just pick the one that produces the best group and ES in velocity.
