I wasn't doubting you, what effect do you think seating the projectiles deeper into the case will have on velocity and pressure, out of curiosity ?

Pressure goes up, 0.25 shorter drops 2.5 grains for the same pressure
@PerazziSC3 beat me too it

As case capacity decreases pressure increases. Pressure = velocity. Putting them deeper, all things equal will raise pressure

...... might have to pull a few then increase in pressure will increase velocity too ?

I have loaded a new ladder at saami COAL from 60gn-62.5gn going up in .5gn increments, I will pull the 62.5 and 62gn loads I am skeptical I will even get that high in the ladder as will be on high alert for pressure signs after todays session.

Have a read of the announcements on the home page. Some email services are causing problems with registration emails.

Unfortunately Gordon who got this going passed away in January. I sincerely hope it can be carried on by someone. I will happily contribute to costs if that is the case. I would even pay a subscription if that's what it takes - it's a fantastic tool. And it's free!!!

Range report....


60gn: 2660fps avg 18fps ES

60.5gn: 2673fps avg 20fps ES

61gn: 2681fps avg 23fps ES

61.5gn: 2695fps avh 25fps ES

61gn shot the best group and would be about 3/4" but it's not really good enough, gonna shelve the 200eldx development for now and wait for Bryn's Targex bullets to turn up.
Pics coming

You dont want to use the 168's?

168 what ?

[Borris]

168gn amax or eld m in you short 300wsm

168gn amax or eld m in you short 300wsm

Unobtainable in the current market

Sell it, must be a dud

No chance.....if @TARGEX bullets dont shoot the way I want, I will just load up some 180gn interloks and use them until I can get the projectiles I want.

What projectiles are you waiting for to become available over what you are currently trialling?

178gn eldms would've been my first choice, hopefully the targex will do the job kinda like the idea of being able to get them without having to bulk hoard them too.

In my 20" 300saum I use 168 NBT. Devastating at all rangers,

These are available, and they have them in 195 grn too. They work well on game. https://www.reloaders.co.nz/shop/Rel...68gr+100s.html

I expect though that the Targex you have coming will be good. Ive never tried a Targex bullet that wouldn't shoot.

Thanks Bruce I'll keep that in mind.....168gn class projectiles are pretty thin on the ground. At this stage I'd like to stay heavy for caliber.
I'll try Targex 190gn and see how they go.....
