I’ve been loading for a 22 Creedmoor that I recently had built and have a question about bullet depth in the case. I want to shoot 88-95 grain bullets but when seated .005 off the lands the long bullets are .5” in the case. This puts the bottom of the bullet below the case body/shoulder point a bit. Is this safe? I assumed the smith knew with a 7 twist barrel I planned on shooting heavy/long bullets but we all know what that makes me.

Some believe that pressure will "grip" the base of a bullet that extends below the case neck into the powder space. It's not true. You'll be fine.

Bullet profile will affect depth..
Obviously a RN carries more weight forward ....

Sounds like a good option for a fast twist creed 💡

Don’t beat around the bush, speak to your gunsmith and if he won’t re throat get someone who knows what they are doing to sort it out

The way pressure works it would seem there would be some of it applied to the body of the bullet inside the case that is not pushing the bullet out of the case. A half inch of bullet down in the case seems like a lot. That said for years I was a big fan of the 300 Winchester magnum and some of the bullets I used extended pretty deep but I had zero issues and every 300 Win Mag I have owned has been a fine shooter.

Pressure IS applied all the way around the circumference of the exposed body of the bullet---equally from all around, resulting in no net lateral movement in any direction. However, the gases cannot grip the bullet's base and therefore it does not impede the bullet's movement out of the neck.

Yeah, make a dummy round or two and have your smith re-throat it appropriately. No biggie.

I have fired 35 rounds now with two different powders and all with the 88 eldm bullet seated what seems to me to be too deep in the case. I shot a 5 shot group today for the first time and it was around 1/2” at 120 yards. Average speed was 3140 FPS with no signs of high pressure and the SD was 42. Maybe I’m over thinking the whole thing and should just shoot some stuff!

I dunno, seems a 223 Remington has had that issue, if it is one, from inception.

The 300 Win. example pales in comparison.

Plus side is you have more throat to work with in terms of erosion down the road. Might give you a few extra rounds on the barrel provided it's safe.

You may run into pressure before you reach published max load because of lack of case capacity. Happened to me on a chamber that was cut really short on freebore.

It may not have been all about capacity. With the really short freebore how close to the lands were you loading compared to what would have been typical for the standard chamber used to develop the published data?

While not optimum you will probably be fine unless you get Donuts on your brass then things turn south, thats why I prefer a bullet seated at or just above the neck shoulder junction.

Some great gunwriter of the olden days said bullets reaching into the case is a minor ballistic crime!
