.300wm Posted February 12, 2015 Report Share Posted February 12, 2015 Hi all, New barrel arrived with gunsmith this week for .300wm, 1/8 twist lothar-walther all good to go and ready to be machined and fitted etc. The plan is to shoot 208gr A-max exclusively, I have only ever used N560 in my 300s up to now but noted on the Viht website that for the heavier bullets they also list N160, N165, N170, and N570. I would like some advice as to which of these powders would: 1. Be best overall for that bullet weight. 2. Run coolest and give longest barrel life 3. Be the most consistent Cheers guys.

dannywayoflife Posted February 13, 2015 Report Share Posted February 13, 2015 N165 has a reputation for burning very cool. I couldn't comment as to its suitability in this application however as not yet owned a .300 Link to comment Share on other sites More sharing options...

terryh Posted February 13, 2015 Report Share Posted February 13, 2015 When I ran a 300WM N165 with 190SMK's and or 210 Bergers. If you look on the web there is published restults of the US military trials for developing loads for the 300WM before its adoption into service, think R19 and 190g SMK's came out tops? There have been developments since then I believe? T Link to comment Share on other sites More sharing options...
.300wm Posted February 13, 2015 Author Report Share Posted February 13, 2015 Thanks Terry, after everyones input and lots of googling I think I am going to settle on N165. Cheers Link to comment Share on other sites More sharing options...
Foxshooter Posted February 13, 2015 Report Share Posted February 13, 2015 I'm currently running N160 with 210gr Bergers and hopefully 209gr Amax in mine MArk Link to comment Share on other sites More sharing options...
.300wm Posted February 14, 2015 Author Report Share Posted February 14, 2015 Care to share your results and data? N160 would be handy as I use that in my .243 Cheers Link to comment Share on other sites More sharing options...
Jagged 77 Posted February 14, 2015 Report Share Posted February 14, 2015 N165 with 208 Amax's for me. Link to comment Share on other sites More sharing options...
Foxshooter Posted February 14, 2015 Report Share Posted February 14, 2015 Was using 70gr N160, Fed GM215M primer Weatherby Brass and 210gr Berger VLD touching the lands. Off the chrono I was getting average 2824fps I have now backed that off to 69gr N160 40 thou off the lands but cant find the velocity figures at the moment. What load data do you have for the 208's and N165 Jagged? MArk Link to comment Share on other sites More sharing options...
