Thread: 223 50gr TTSX BM2

Gidday,

Looking for load data on the 50gr TTSX using BM2. Can’t seem to find it documented anywhere.

Any advice appreciated.

Cheers

Found by searching "Barnes 223 load data".

Hodgdon Benchmark = ADI BM2.

Thank you. Didn’t know they were same powder when I’d seen that earlier .

Just use 50 grain data and work up..they are awesome projectiles.

Greetings,
Only data for Barnes projectiles should be used for loading them as they are longer and harder than the same weight lead core projectiles and will give higher pressure.
GPM.

My understanding was that the Barnes relief rings actually lower pressure?
Their published data appears to be right up there with the warmest cup and core data in manuals.

Greetings @Tahr,
I don't have any actual experience with Barnes projectiles as they are beyond my cheap skate price. Comparing their book data for the 150 grain in the .308 they seem to get the same velocity with 1.5 grains less powder than I have chronographed with AR2206H in a 24" barrel.
GPM.

I suppose it doesn't matter much really so long as you begin conservatively.
I did find this though: https://www.google.com/search?client...UTF-8&oe=UTF-8

My loads are the same with them as with cup n core...if not hot rodding to begin with you should be fine.

Greetings,
I also found that the Nosler 129 grain LRAB gave almost 100 fps more velocity than the Hornady 129 grain soft point in the 6.5-06 with everything else the same so the heavy jacketed projectiles seem to push up velocity and pressure as well as the mono's. I relly should try some I suppose.

27gr BM2. Use 26gr with 53gr TSX. Brutal and accurate.

Have you been reading NZ hunter?

@Greg Duley should try some 80gr ELDM or 77gr TMK ..! Obviously no good for NZTF work, but outside that you'll be pleasantly surprised out at the ranges where the non-lead bullets stop working

Have a look at the data from Charliehorse above. More powder with the ttsx in the max loads compared to the cup and core in same wt. A bit of a surprise there.

No I hadn’t till about 10 minutes ago. Turns out I get 5 free articles if using the ZINIO app to view the magazine online. Good read.
I was talking to a mate who has some association with DOC and their non toxic ammo supply.

I’m going to OIA the cost of their non toxic centrefire ammo because I don’t believe the number he told me they pay per round to procure.

I always want to have a tutu after reading many a thread online about many of the copper projectiles and sending them at warp speed.
