.224 case volumes

[300SALRH]

Sure it would be of great value if we can try and consolidate the case volumes of various .224 cartridges into one post, anything from a the smallest to largest cartridge that shoots a 224 bullet. Info that would be required is the cartridge, water volume, brass brand and parent case and brand. Just copy this next section and complete.

Cartridge:
Volume (H2O gr):
Brand:
Parent case:

This is what I have for the 22-250 Ackley Improved formed from 22-250 Lapua brass

Cartridge: 22-250 Ackley Improved
Volume (H2O gr): 50.4gr
Brand: Lapua
Parent case: Lapua - 22-250 Remington

How do you come about this? Fired case, spent primer in place, fill to tippy top, pour in scale pan? Never done it, need a little primer. DW

I can get you fire-formed volumes for .223 Rem, .220 Swift, and .223 WSSM tonight. I know some of the volumes in the more popular cartridges will be all over the place. I'd bet from lot-to-lot within manufacturers too. I have a friend who's been wildcatting .30 carbine brass and the stubby little cases can vary in weight by 20% depending on headstamp.

1. Weigh a empty fired case with spent primer - Empty grain weight
2. Take the same case and fill the case with water with water level to case mouth.
3. Weigh the case filled with water - Filled grain weight
4. Subtract filled weight from empty weight = volume of H2O in grains

My most recent .22 Caliber build is a 224 Terminator from Defensive Edge Rifles. I have a couple others but I don't recall their case capacities off the top of my head so I'll edit my post later with that information.

Cartridge: 224 Terminator (A version of 22-243 Improved w/35degree shoulder)

Case capacity: 55.70gr H2O (fully formed case)

Brand of brass: Lapua

Parent case: Lapua 243 Win.

Nothing like cutting right to the chase .

However, if you want really accurate case volumes, you need to measure the water volume of cases from your rifle. It may or may not be the same as another, even when using the same Lot# of brass. Case volume determination is not that difficult, but can be time-consuming if you want to do a large number of cases (i.e. >10-20 cases).
