I’m reading that the 6.5 cm is better than the 260 rem only because heavy bullets must be seated deeper due to magazine dimensions. My 260 is on a Mauser 98 action so magazine size is not a factor. How much longer can I seat the 140 gr BT? My old eyes are too tired (s) to fool around with measuring with a marked dowel and wasting ammo testing when all I want is a reliable hunting load. Chamber and throat dimensions are pretty much standard right?

Yes if you are just looking for a standard hunting load and not wanting to mess around for the 260 I would just use the nosler load data for the 140's at 2.80 and they actually show the 260 faster than the 6.5.
Im on a trip now but when I'm home next week i can add what my COL is on my 260

If you don't want to use a dowel - why not the cut-neck method?
Or making a dummy with a bullet set far out and setting it deeper, until the bolt closes without force?

Make a dummy round with bullet seated out and coat it with a sharpie. Then keep chambering, coating and seating until there is no marks from the lands on the bullet. Not hard and doesn't cost much or take long. Dan.

I love a good M98 action. In all my rifles, I always load for magazine size but you are saying that magazine size is not a factor. Can you explain? What model rifle are you using? Why is the magazine not a factor in your case? For me, I would load the bullets out as far as my mag will allow me with a tiny margin for error to ensure smooth feeding. For hunting grade accuracy, I have never found bullet seating depth to be an issue. Could I be so bold (acknowledging I don't know your setup or motiviations) to suggest you could be over thinking it?
