Hi more load data needed
Looking for any load data for 6.5x284 cartridge using N140 powder
Rifle used will be Unique Alpine TPG 1 with a 26'' barrel with a 1/10 twist

Unique Alpine TPG 1
26'' barrel with a 1/10 twist
Bullet will be Amax 140 seated at COAL 3070
Please give a N140 load and fps for shooting out to 800-1100 meters

Thanks
Andy

Have you got a job lot of N140 :)

I would have thought it was a tad quick for the 140's - I would look at H4831SC or N560 or maybe even 4350.

I will put the numbers into the machine

Hi YES
I have have just got a Unique Alpine TPG 1 with three barrels 308, 6mmbr, and 6.5x284
need load for N140 as i know that's a powder i can always get plus i don't like holding to many different powders.

youll find that 140 is too qiuick a powdwer for the 6.5-284 benn there done that

you are better off with 51-52 grains of 4831sc

Given your COAL/powder/bullet choice the indicated max load at 65,000 PSI on a reasonable UK day is going to be a tad over 46 grains of N140 will give you just over 2800fps.

Push the load up to say 47grains still leaves you 14+% unused case volume and you are still under 2900fps. This is not an 1100m load

H4831SC/H4350 or N560 is going to do the job with less pressure and a better MV

Hi
If you were loading this cartridge what load would you use with a Amax 140 bullet i have 800 hundred Amax heads, so will be on them for sometime
Sorry its a 1/8 twist not 1/10

Andy

i have this cartridge and this is my recipe


140 g amax
51.5 g 4831sc
fed 210 m primer
lapua case
2.513 to ogive
@ 2890 fps


what else do you wanna know


if you dont like the amax ill buy them off you if you want

send us a pm

I prefer Vihtavouri powder and the Viking liked Hodgdon powders.

N560 - you could push the Amax's to 3050/3100 with a hot load however I would suggest starting with 51/52 grains and move up slowly.

My view is anymore than 2950fps in unnecessary.
