    TR-140 load data

    Hi,
    does anyone have load data for TR-140 powder or 223/5.56?
    Thanks in advance
    regards

    Why not email commonside@compuserve.com and ask with specific reference to the bullets you intend using?
    I use TR140 in 7.62, .303 and .243 and that's how i got my data.

    As an aside, might it be a bit slow for .223? I have a .223 on order, and have already loaded a test series of cartridges with one of the quicker RS powders for it, with 52gr bullets. I guess TR140 might be a goer with heavy-for-cal bullets in .223?

    Have you looked at this website http://www.full-bore.co.uk/index.php...6d7dd3c3886d13
    There's quite a bit of information on the site regarding reloading with various calibres with TR140, all you need to do is use the search facility.

    I have fairly recently started using TR140 with my .223rem myself and all I will say is that the results aren't too shabby, but no where as good as with N130. I started off with info from that site that other shooters supplied and from the Vihtavuori website using data for N140 as a very rough guide. The usual caution is applied when using data from other than official sources such as the powder manufacturers.
    It's the calibre of the shooter that counts not the calibre of the rifle.

    It is VERY close to Viht N140 in the 223. I got near identical MVs over a range of loads with charges of the two powders.

    TR140 is a Nitro-Chemie manufactured 'Reload Swiss' brand propellant that has been made available here in a relatively small way and a 'semi-official' capacity. Sometime over the next few months, the Reload Swiss range is to be officially launched here complete with pressure-tested loads data.

    TR140's 'proper' title is RS50. It's probably a canister version of the bulk powder that RUAG buys to load .308 Win / 7.62mm. The other powder that's been referred to is most likely RS40, a 'high-energy' (the base nitrocellulose kernels infused by an amount of nitroglycerine, as per the Viht N500-series powders) type. It's much faster burning than TR140 / RS50 and was developed by N-C for the Swiss and some other European countries' version of the current 5.56mm milspec round that gives a 62gn bullet ~3,100 fps in a typical assault rifle. N-C shows it having a similar burning rate to Viht N530, and it should prove very well suited to 223 Rem with 50-69gn bullets.

    To say I use it would be misleading, as I don't yet have a .223 - however, the powder I intend trying is, as Laurie suggests, RS40.

    I throw 55gr hp's through my .223 with 23gr of tr140 behind them. Shoots and groups like a diamond. I used vit n140 before that with 22.5gr BUT at 58/kilo tr140 is my friend...

    Any suggestions where the best prices for powders are? I bought 2* 1kg TR140 from ITL shooting for 57.50 per kilo.

    I used to use tr140 in my 223 before I sold it. It was very good in that role! I was using 75 Amax and 80 jlk's they went very very well!
