Mistem,

Please share any results you work up. I have recent 350 Rem Mag purchase but my gun range has a ban on calibers over 7mm (long story). Needless to say, I haven't done much reloading for it except for 200 TTSX and TAC. I am looking for a less expensive deer load with the 200 Interlock.

I contacted Ramshot powders and asked for data by email for 350mag data with TAC powder. I got a quick reply. I lost the data when I had to reload software.

Here's some data I got from shooting a 700 Classic. The 225 load was straight from Barnes manual, the 250-grain load was a scientific guesstimate:

225 Barnes TSX/62.0 TAC/Rem. case/CCI 200 primer--2660 fps
250 Nosler Part/59.0 TAC/ " /Rem. 9-1/2------2561 fps

Thanks for all the information....I sent an e-mail off to Keith at Ramshot for current data.

I was able to play some the last couple of days with my 350 RM and 200 gr SP and Flex Hornadys.
Here's the data from my Ruger with a 20" factory barrel chopped and sights installed:
200 gr Hornady SP,R-P Brass, 215 Primer, Lee Factory Crimped, OAL 2.855"

61.0 2844 3592 25.6
62.0 2862 3637 211.3

None of these loads showed any signs of excessive pressure in my rifle. I plan on loading more with 60,61 and 62 grs and shoot more groups...they looked promising even using a 4X scope.

I would try 60.5 61.0 and 61.5. At 62 it looks like the velocity is not gaining much and the deviation is increasing.
