I got what bullets I need for pistols. I’m looking for a long, WFN 6.5 for my WW M96 Swede!
Lead? How long?
Lead/160gr
Here's where the real "fun" can begin. (And thread drift
) As I found with the .30-06, it can be a challenge to get up to a cartridge's max jacketed projectile weight - i.e. 220 grains for the '06 - when using cast.
Ideally, you seat the bullet so that the sides of the gas check are contained within the neck of the case - primarily to ensure the check doesn't fall off, but also to keep the lube grooves isolated from the powder.
The shank of the bullet is ideally sized to 0.001"-0.002" over groove diameter. How long a shank you can get away with on a bottlenecked case is dictated by the measurement of rear of case neck to where that diameter would collide with the rear of the throat.
A common practice for the nose length is to use a "bore rider" bullet design where the nose section is the exact diameter of, and therefore a slip fit in, the smaller bore diameter. If your mold isn't spec'd just right for your alloy, that diameter can end up too small (accuracy SUCKS), or too large (good luck chambering the heavy weights), and it isn't practical to die-size the nose diameter like one does for the shank.
So between the bore and groove diameters, neck length, throat length (by cut or wear), and potentially mag box length, it's easy to collide with issues where max "factory" weight just doesn't properly fit the gun. . .and you'll likely be really limited by what nose shape you can pull off maintaining that weight. You just don't have the room to fiddle with seating depth that jacketed can give you.
I don't run a 6.5 of any description, so may be talking out of my butt, but without making a swage-cast of the chamber/throat to get those measurements, I'd be really hesitant to take the plunge on a mold going to the full 160-162 grains.
Here's links to a couple of NOE's 6.5 options:

That's a 140 grainer with a tapered ogive that can chase up into the bore diameter at the throat, and a tapered front driving band that can likewise be chased up to contact the throat's groove diameter. A fair bit of flexibility and wiggle-room.
Here's more the traditional 163 grainer:

Note the short ogive on the nose and the long, parallel sides of the .262" diameter, bore-riding nose section. If the throat doesn't allow that nose to chamber readily, things rapidly decline into needing to seat the base of the shank too deeply into the case. Not saying you can't or it won't, but I've had my ass kicked a couple of times with mold purchases that were at the extreme upper end of the tolerance range.
With luck, a Swede gives you the necessary space. Cautionary tales, free of charge.
