Dents on Case After Firing

[300WSM]

Oil....your load is light but that is not making your case dent. You have excessive oil in the chamber.

Want to see something for your own settlement?? Put too much oil on a case and full length re-size it. When you lower it out of the die set your pretty case will have a dent on it.

Same thing is going on here. Your case is expanding when it is fired. The oil has no place else to go but in the form of the dent in the case.

I don't know what caused that, but i do know for a fact that the military guys here have seen that before.

I've seen it tons of times, while firing 5.56 at the range!

Are you thinking it is a double feeding 5.56 :twisted: The under bullet trys to enter the chamber same time. Your right, it's common with the M4's. Hopefully that 300 WBY isn't double feeding though! HA

Now... if we could just get a AR10 platform in 300 WBY I'd be a happy man!

A .300 Bee in an AR10 would be called the "Arthritis Maker"!

Wouln't be bad. Recoil would be significantly less than the normal Mark v or vanguard etc etc

Clean your chamber very well. Start at 80 gr you should max out at 84 or so.

Berger data is about THE weaniest data available. Maybe they figure everyone is running custom rifles with super tight tolerances and throats that put the bullet in the rifling at ignition.

It seems like most of Berger's data is just QL information, put into print.

I think I noticed that while looking at their data a while back....but they must be cutting off "Max" at about 55k pressure!
Ramshot is another that seems suspiciously close to or mirroring ql.

That's about what I have seen too.. With QL, the books are good reading material, and a good powder adviser, but QL rules the roost most of the time these days.
