Viht N140 for 7mm-08

[thefoxandthe.243]

Hi,
Does anyone have any load data for N140 with 139gr SST?
On the Viht app, it shows only 130gr and 140gr.
I'm looking for info specific to the 139gr sst, looking for start load and maximum load.

Thanks.

Ps I have tried Winchester Staball, and didn't see great results. I already have Viht N140 for loading my .243, so would like to try that 1st before buying another powder.

Just use the 140 data

139 sst my go to bullet for the 7mm08 , I used data for 140 just started low. I find they knock everything off its feet ,but get it wrong and they can be very messy !!

Out of interest, is it N140 you use? And what's your data? Thanks

No sorry good old H380

I have used N140 in my 7-08 accuracy was near the top end of the data. I found it quite snappy and much prefer Varget. Which of course is now unobtainable.

I will move to N150 when my varget runs out. It works well in my 6.5X47 and .308.

I was thinking about using N150 as it is a little faster than the N140.
I might just bite the bullet (excuse the pun) and buy a tub of N150

42 grain n140 . Worked in 3 7mm08 barrels I've had. That's with SST and 140 pro hunters. Gives around 2800fps in a 22 " barrel.

I’ve used N140, varget, RL17, but settled on Varget. RL17 was to slow in my opinion for 139/ 140gn and has the same burning rate as N150. N140 just didn’t quite do it for me either, I felt it just wast quick enough to achieve the velocity’s I was looking for and was probably still burning outside the barrel. I like to get the velocity up beyond where I want to be with a bit of capacity left over and then drop back a bit untill I find an accuracy node.
If you’re wanting to stick with vithavouri powders and looking for something a bit quicker, I’d try N135 or possibly n130, but I’d suggest that n130’s probably a bit quick for 140gns. N135’s fairly close to Varget.
These days I’m using Rs52 behind a 130gn fox non lead and it seems to be doing the business quite nicely.

Other way round.

N140 is faster than N150.

Sorry, I was on about expected velocity not burn rate
