Not even worth the [bleep] effort...


16 Sure.....advantage is small.

Point being it isn't worth chasing it in the little case just to show you can reach velocities with it that you won't see anywhere else credible.(pressure tested). You aren't breaking any new ground or proving a thing....just stuffing more powder in and it doesn't take any brains to do that.

If we want it,then we can have it.....just buy a bigger cartridge. smile

Of course this may require compromises like a longer or fatter case,a slightly heavier rifle, etc. Part of the game.


On a side note, here's a hypothetical. You try this new powder. 7-08, 120 ttsx. You are not seeing any pressure sign. Velocity is very high and you are not near max. Exactly what velocity do you stop at?


I will generally load to book maximum velocity if I can get there with no obvious signs of pressure.
If that is the case I will proceed carefully until I do notice pressure then back off accordingly
The main thing I am looking for is incremental increases in velocity, as soon as this diminishes I believe an over pressure situation is occurring, often noticed just before bolt lift comes into play.
