RG-4895 info needed

[jeeptim]

Good Morning!
Finnaly the expensive Califorina sunshine has showed! Woo Hoo.
So got a deal on 8lb of RG-4895 $90.00 8lb couldn't pass it up.
Is the load data same as IMR-4895 or H-4895.
Currently shooting lots of and have components for...
223/5.65 55gr FMJs.
300 B/O 147gr FMJs.
458 Socom 325 FTX.
Especially interested in data for the 458 I'm thinking the powder is just to slow.
Any tried and proven load data for the above or place to find this info would be super helpful.
I do load and shoot ...
303Brit.
7.62x54r
30/30
7mm Rem Mag
30/06
308.
7.62x39
8mm mauser
But have tons of these loaded and I don't shoot these much.
It's funny I resisted the AR platform for years now they are my go to rifles.
Thanx

RG-4895 is the British version of IMR-4895. While the data is SIMILAR it is not exactly the same. You can use the IMR data as a guide but you must start low and work up just like you would with WC844. Nice score!
