Load data for Sierra 180 gr TGK .308

[timdvmtpa]

The only load data I can find is for the 165 gr anyone have a good data source for this bullet?

What powder are you planning to use?

Also, the TMK in available in 175gr and 195gr, not the 180gr. The 180gr is the HPBT MK.

H4831 , I have 30 cal 180 gr Sierra TGK bullets(#4680)

My bad, I read wrong, read TMK not TGK. However I still dont see it on the Sierra App, and nothing with H4831 and 180gr bullets either. Hogdon also has no data for 308 Win and H4831 with 180gr bullets

See image with no 180gr TGK

No H4831 with 180gr bullets

Varget and CFE223 are a good option

Forgor to mention, H4831 is designed for larger cartridges like the 270, 30-06 and magnun cartridges.


I do see the bullets on the Sierra line up but just not on the app. You can still use the load data from the other 180gr bullets, the app show the same minimum loads and max loas for all 180gr bullets.

Hope this helps and stay safe

Thanks I will use the 180 gr data, I'm loading 300 WinMag.

That changes things, you wrote 308 so I gave you 308 Win data, so ignora that

Starting load

You start hitting max at 75.1gr, this is with Short Cut version

Sierra stated to use their standard 180 grain data. I would suggest contacting them to confirm they still recommend what I was told for the same bullet.

However, IF you have RL26 pixie dust, I am shooting the 180 TGK out of my G1 Sendero 300WM at light speed . Shot exceptionally well with RL26. Suggest considering it if you have some to spare.

Always work up loads in your own rifle since this load was for my specific rifle at the CBTO measurements that worked in my rifle and not necessarily yours. Always use safe reloading practices and start at reasonable loads.

Thanks, does the sc have a faster burn rate than the regular 4831?
