6.5mm Swede balistics at modern day pressures?

[Changeling]

Does anyone have a source for the 6.5 x 55 Swedish Mauser cartridge with 140 gr modern bullets like Nosler/Hornady/whatever at modern pressures (Listed) in barrels of at LEAST 24 inches
All I seem to be able to find is reloading data with pressures about 45,000 in 18 and 22 inch barrels!

I do realize that the older weapons are a concern, however the newer weapons/brass are not regulated to these low pressures or shouldn't be.

Nosler publishes modern pressure loads, Quickload might also be helpful if you know your case volume.

I have some data. florida high humidity well learned data, may not help much in a colder climate, the best you can do is take your items to the range and start playing till some pressure sighns arrise then back off to a safe node then play wit seating depth till a happy compomise is met. Good luck, i would suggest a 140gr Amax at 44gr of H4350. if the throat is of sami spec try to jump about .015 to .050

You can go to noslers online and they have published data but be careful as it is for their own bullets and if using another brand start low and work up.

From my experience if you use the slow burning powders that work best, 4350 to 4831 burn rate, you can't get enough powder in the case to be too much. According to the Accurate manual the max loads with 120s 46 grs AA4350 and 45 grs AA4350 with 140s are under 46,000 CUP but are COMPRESSED loads. Out of my 29" barrel Sported M-96 Mauser I average 3000 fps with the 120 Nosler BT and Sierra SP and 2800 fps with 140 Hornady and Sierra sp. Both loads a very accurate and kill deer like lightening struck them. That long barrel really adds velocity. ;D
