Just playing with ideas and wondered what powders people are using with 130gr TTSX in their .308?
I have used it in 375 !!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![]()
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.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.
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.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.

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

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

More speed does not extend the range. Not with a lighter lighter bullet ceteris paribus.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.
Back then I was using H335 which was the Barnes "Best Powder" choice and had been using IMR4895I wonder what you folks had done if Vihtavuori had really stopped producing back in 2013.

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).Just playing with ideas and wondered what powders people are using with 130gr TTSX in their .308?
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.Ahah! So Sundog dropped from 150 to 130gns. That makes sense now. I guess there is a clue in the thread title. Thanks R
