If you are going to be shooting through the magazine you will not be able to reach the lands with the bullet. Load to magazine length. I load mine to 3.050 and it works through the magazine perfectly and is accurate at that length with most everything I have tried.
I have had best luck with 37.8 grs IMR 4895, CCI BR2 primers, 140 gr Sierra Match King, Rem cases, OAL 3.050 as a target load. This is a mild load but it is very accurate.
For a really accurate MAX 46,000 CUP range load that the Swede M-96 is listed for that I use for deer hunting etc.
Accurate Arms 4350 45.0 grs, Federal 210M Match primer, Rem case, 140 Hornady SP or Sierra SP, OAL 3.050 will do 2800 fps from the 29" barrel of M-96.
Accurate Arms 4350 46.0 grs, Federal 210M Match primer, Rem case, 120 Nosler ballistic tip, OAL 3.050 will do 3000 fps from 29" barrel of M-96.
Both of the loads are MAX according to Accurate Arms manual but they are really accurate and they hammer deer. I have four M-96s and one M-38/96. One of the M-96s has been sported with a Bold trigger, scope mounted in Leupold base and rings, new bolt handle welded on and a composite stock that I do some hunting with.
