Seating a bullet half way down the neck only?

Hi there.

Seating a bullet half way down the neck to get it close to the lands vs using the whole neck length for seating?

Based on what I have read I believe that I will have a more consistent launch when I use the whole neck to seat the bullet. I like seating my bullets fairly close to the lands but with this particular bullet I can only seat it a little over half way down the neck.

Any info would help, thank you.

General "rule" is at least one caliber length deep.

What specifically are you loading and in what kind of rifle?

For my problematic Kimber 338 WM. I am loading 180g accubonds to see if their gliding metal would leave less copper in my barrel. I know I am making my 338 a 30 cal but just want to see if the bullet works in the rifle. Will use it for both hunting and just plain shooting. Other guys feel that it must be seated about as deep as the diameter of your caliber for hunting as the recoil and bumps to your rifle might 'move' the bullet from its perfect seating pos in the magazine (just others' opinion I guess).

Find the lands and seat the bullet .015 to .03 off them, if your magazine will allow. The accubond is a long bullet, even the 180 grain .338. Don't worry about how much is in the neck of the case.

The seat to caliber depth at least is a misnomer to me. My "general rule" is to always seat to a light jam fit or as close to that as I can get. Sometimes meant adding a light crimp with SAAMI chambers. And sometimes I had to back off for a little jump for the best accruacy, but not very often. I had a lot of custom chambers that were cut for specific bullets to have the best of both worlds.

Thanks a lot. I do appreciate the information.

I will see what they do when I seat them close to the rifling

In the first Barnes copper bullets, there was a note in each box that said to stay .050 away from the lands, because of pressure with the copper bullets, i have seen the Early German Wby Rifles with a inch or a little more freebore, it was changed later to .500, which they still use, i have heard people bad mouth this much freebore, but have seen some nice groups out of these Rifles, we have to remember their Hunting Rifles, not Bench Rest Rifles

I use 210 Nosler partitions and load them to fit the magazine and they shoot very well and are velocity is around 3042 fps.
Load them to fit the magazine.

When I loaded a bunch of 6.5mm Swede, I found the long bullets worked really well for seating out of the neck with just a little under 8mm length in the case neck. Seemed like my accuracy was the best when the bullet was about 7.75mm in the case neck, however, some magazines will not allow enough room for that. A Swede Mauser and a Mark X Mauser were fine, but the mag space on a Remington 700 was smaller
