Thread: 300 Rum Brass Cases

SAME cases
SAME powder
SAME projectile
MORE powder

So where did the excuess pressure go?
Why would i tell everyone the little bits i done to reduce the pressure?

I showed everything that was needed................

I would gueSs it has been forced into and threw the lands before peak pressure rise with the higher load and not with the lower.
But Im just guessing.

Same chamber that was showing pressure signs lower?
Or chamge of barrel chamber etc?

I must have missed this bit unless the way to make a safer faster load is make it a bit longer and put more powder in

Google edge +p is what i always get told..............

It has gone over a few heads and it did mine for a start until It was pointed out I couldn't read properly. The brass and chamber are the same. More powder than the original load after a process Abe has done has resulted in less pressure.

+OAL

Normal loading for 300 RUM with 2225 in the 90s then +5 still in the 90s

so what did you do?

Plot pressure over time and bullet travel over time on the same axis and you will start to see things...

The point i am trying to make is Tui said he had explained a simple way to increase speed and lower pressure. When really he had not explained anything.

Following his advice for a safe load i should cram 4 more grains of powder into my just touch load and increase length to a jam and i just know that will end badly in my 308

Or put another way as a complete novice reading this thread i will go out in the shed and load up a heap of rounds for ol Betsy 4 grains over pressure signs and a bit longer and its good to go cos that's the secret:thumbup:

I never said what I done, nor did I say to copy the load. . . .

Nor am I going to say that would be silly

Anyone that has a standard edge will know NOT to go over 94gr or is that what people do to get speed? Next time I'll just get hard brass. . . . . .. an not worrie

No. A bit more to it than that. And safer.
I think it was meant to be a question of how he achieved this. Not anything more.
