Barnes TSX .308 bullets

#1 Post by Graham M »

At the moment I am shooting 150 grn soft point Sierra Gamekings for deer, using grns of Reloader 15 through a Howa 1-10 barrel.
I am going to reload some 130grn Barnes TSX bullets as I have read on the internet that going down from 150 grns is the thing to do.
But!! I am now wondering if I should have simply stayed with the same weight of 150grns; but would this mean using a longer bullet and as such would my 1-10 be too slow?

At the moment I am still in the dark about using a copper bullet and I'm still not sure if my R15 would still be suitable.
Anyone shooting these bullets??

I do have a tub of H335 which is a bit faster.

If stability is the concern you can calculate it here:

Get the lengths for your specific bullet choices here:

There appear to be two forms of Barnes TSX .308" 150gr, but even the longer one looks to be stable in a 1:10" at relatively low velocities. Work it out with your specific data.

Abide by the forum rules and reference the pressure tested data that your load is from.

The maximum load shows 49grns but I ended up using 48grns as this was the most accurate loading.

Cheers rox. I have sent for the shorter flat nosed bullets and that one seems to be in the stable zone.
Thanks for the info thankssign

Sorry Adam never gave it a thought that I was putting up a dangerous load as it's the one I have used since they took away my H4895

Just looked up the new loading data for Aliant powders and the NEW max load is 46.8grns. So it looks as though Aliant has reduced their loading data for R15 and 150grn Sierra Gamekings.

I have been using barnes 150gr for many years now. 44 grains of vt140. Through a tikka continental. Very accurate and all deer just drop on the spot. What's not to like?
Aye, they do cost a lot !
