.308 TTSX 130gr

N140 or N135 and I had good results with H4895 when I could get it.
the N140 is a touch slow and I have had to compress loads to get up to 3000fps in some rifles (20 inch barrels) but it can be done. I got 3100 from N135
 
N140 is fast becoming my powder of choice for just about everything, it works in my .204, 6.5swede and .308.......if I work up a load for my .375 then it will be a one-stop shop👍
 
I wonder what you folks had done if Vihtavuori had really stopped producing back in 2013.
 
N-140. 48 grains so it's compressed but no pressure signs.I seated the bullets to my usual prohunter depth and accuracy was ok at around a consistent inch but then seated them to give more jump and the group size shrunk considerably.

Big fan of Prohunters and Viht - N120 for .222, N160 for 6.5x55 and N140 for .308/7.62x54R/8mm but have not yet tried copper. Might just try it for the 6.5 and 308 but can I ask when you seated them to your usual PH depth and on the assumption that they are longer (?) than PHs did they sit deeper in the neck in the first place i.e. before you increased the jump? Sorry if that sounds like a silly question but curious.

Certainly. That‘s why you normally go lighter with copper bullets (e.g. 130 instead of 150 grs.), even though this is not the main reason, which is stabilizing the bullet properly and increasing velocity for good expansion.

Ahah! So Sundog dropped from 150 to 130gns. That makes sense now. I guess there is a clue in the thread title. Thanks R

Not sure what Sundog did. But the concept of going lighter in bullet weight also implies that you use a slightly faster powder, which is why I find N140 suboptimal for 130 grs. bullets in the .308. It may certainly work well, but it could work better.
 
I’m dropping from 150gr Speer SPBT to Barnes TTSX 130gr to get a bit more speed to extend the range and stabilise the bullet.
More speed does not extend the range. Not with a lighter lighter bullet ceteris paribus.
 
Just playing with ideas and wondered what powders people are using with 130gr TTSX in their .308?
Still using IMR4895 from my stockpile - works very well with this head and have taken reds, roe, fallow and muntjac with them. (Many thanks to Alantoo for assisting me to chrono prior to using them up on Arran last year).

Incidentally, I have 2 unopened pots of IMR4985 up for sale in the reloading section :cool:

Aye, sorry I wasn't clear. I was using 150 grain Sierra Prohunter in my 308. It's got a 20 inch Krieger barrel and is superbly accurate with these bullets using N-140. I'm now using Barnes 130 grain. I seated them to my prohunter coal and they were grouping about an inch or less but found when seated a wee bit deeper accuracy is as good as the prohunter bullets. I've seated them so that the first relief groove shows.
Taken on board that 140 might not be the ideal powder but it seems to work very well for me and it's what I've got in the cupboard 😀
Very happy with the Barnes performance on the deer I've shot so far too
