N133

[BULLET 05]

i have found a load for my 6br using n133. Can someone tell me what the book says max load is for a 87 gr Bullet? Thanks

I took a look in my manuals and neither show 133. Took a couple pics of what they do show. Sorry couldn't be more help .

Found this after a brief search:https://www.vihtavuori.com/reloading-data/rifle-reloading/?cartridge=63

If I read this correctly, Vihtavuori feels that N133 is a bit fast for the 87g, recommending N140, N150, and N540 powders instead. I do see it for the 70 gr Sierra, so some interpolation of data may produce a workable load.

I've got some N133 I've been dying to try, so please do come-on back and share your results.

133 probably won’t be your best bet. I have a load I use in all my 6 BRs and it’s a friggen tack driving machine.
32.0 grains Varget using the Berger 87 gr Hunting VLD. Try it.

I have a good amount of N133 and I tried it when I got my br. I used 31.0 gr and it shot pretty darn good for the first try. I can’t remember where I got the load data so I was trying to find it again.

I know all rifles are different and chambers and freebore but 31 grs 133 and an 87 gr bullet sounds hotter than crap..

I think you are right. I did not have any primer pocket issues with the few that I loaded. Apparently I may have goofed when looking up loads. I still may try the n133 but with 28 grain range. Or just save the n133 for a lighter Bullet.

I have shot 30.5 133 with Barts 68BT in a 6BR that shot really good,,it would seem 20 more grains of bullet would make some serious pressure,,

28 to 29 grains of 133 under a 60 or so grain bullet is pretty much the standard fare for 6PPC. I would expect 133 to be too fast for a 6BR with any bullet let alone an 87gr.
