Well I've had a break through & finally found the missing 6 grains of water

Here it is.



Here it is pictured next to a 375 Lunatic & 338 DCM



It is a 50 cal Lunatic not a 375....

That .50's pretty ugly.

I must be missing something here... Who cares?

I don't get it? But glad, you found all 6 of them.

Here they are with a 375 CE projectile & their water capacities, full to the top of the neck with filtered water.



375 RUM imp, 375 Terminator, 380 Terminator, 375 Lunatic, 375 DCM & 375 VM2 imp.

It has been interesting comparing performance

what came out on top in performance?

With the rig I used, Barnard P-Chey, 1.35", 32" barrel, the 375 DCM was the best.

I believe the 375 VM2 & a similar one not pictured will be faster than the DCM, but the rigs weigh considerably more useing a 50 BMG style action & 1.75" 36"+ barrel.

There maybe only 50-150 FPS in it hard to say at present as there is so little data available for them.

They will also cost a fair bit more to build, so it is hard to say whether or not they will be worth it.

Any increase in performance is helpful once you start getting out past 2000 yards

Depending on the outcome I may build one on my 416 Barrett, if it doesn't sell.....

I would like to put the brass & dies I have to good use.....

Looking at those cases actual powder capacity (base to shoulder neck junction) would have to go to the lunatic?

The necks are the same length give or take a thou, in the same brass they have the same internal capacity.

The DCM diameter is smaller at the base & bigger at the shoulder than the Lunatic by a small amount each way.

Actually that is not true Greg. The Lunatic has more total capacity than the DCM in the same brass and even more so when measured to the neck shoulder junction.

If you are going to call others about misleading capacities don't start doing it yourself.

Thanks for your input Luke

Do you have a bit of 375 DCM & 375 Lunatic brass in front of you ?

Did you watch the video I put in this post ?

It is pretty clear, simple & straight forward.

So you can see how easy it is to measure case capacity.

375 Lunatic & 375 DCM case capacity. - YouTube

Yes the DCM had .5 grain less water in that video, .5 of a grain is very little water, I can weigh it again & get it .5 grain over no problem.

That video was made in one take no editing.....

That's correct Greg. Based on the early discussions I had with you the difference was about 1 grain of water in favour of the lunatic.

It's ok to say the Lunatic had more capacity Greg, it also has a longer neck. Both those points make it a slightly better designed wildcat of the cheytac case in my opinion.

I don't care if its only 1gr or half a grain, the truth is the lunatic is bigger, and when you are calling others liars you better not be lying yourself.

This is a copy paste of the text you sent me.

Just formed a piece of jamerson lunatic into DCM brass what an arse to do ... It holds 172.9grains of water so there is about 1 grain difference not 6 .... All BS ....

So its not 6 then and its all bs?
Last time a checked the bullet goes in the neck so any extra capacity from a longer neck is null and void yea?
