    .308 and Vit. N-150

    Hey Guys,

    I'm in need of a little help. I was given about 8lbs. of both Vit. N-150 and N-135 powder. I wanted to know from those of you with experience with these powders what some good loads are for .308. I will be using 155gr. Lapua Scenars, 155gr. Palma Match (2156), and of course 175gr. SMK's. If anyone knows of some good starting points or good loads let me know. I will be running these loads out of any of the following rifles:
    Savage 10fcp, Savage 10 BA, and Rem 700P.
    I know very little about this powder and don't have the time at the moment to do a bunch of research. The 175gr. SMK's and 155gr. Lapua Scenars are the most important right now as I have a lot of bullets in each. Any and all help is greatly appreciated!
    I do plan on taking the best load I can to 1,000m. Sorry almost forgot to put that in.

    The burn rate on N150 is about the same as H4350 and RE17 (2) steps slower than Varget. The N135 slightly faster than Varget. You can see these comparisons on the Lapua web site.

    The N150 is a good powder for 1000 yard loads and really shines in long loaded single shot F TR type rifles. With that said in a magazine length 308 I would use N140 or try the N135. I hear good things of the N135 but have never used that fast of powder in my 308s.

    Thanks Mike and Sully.
    I went ahead and did some research even though I've got so much going, I didn't want to start way to low when making loads and wasting powder, but in the end I kind of had to. Doesn't look like very many people use the Viht. N-135's or N-150's for long range loads. Least its been hard trying to find someone who has good data for long range 155's or 175gr loads. I just started at 41.5gr of the N-150 and went up every .3gr for the 175gr SMK's and started at 44gr. of N-150 and went up every .3gr for the 155gr Lap. Scenars.
    I haven't started with the N-135 yet so if anyone has a good starting point for a .308 in both 155gr. Lap Scenars and 175gr SMK's please let me know. I haven't found hardly anything on loads for the Viht. N-135.
    I would really appreciate any help wih a good starting point. If not I guess I'll back off from what I started with on my N-150 loads.
    Good thing for everyone here is I will post what works best for these powders and bullets above. I'll be trying them in a Savage 10fcp, Savage 10 BA, and Rem 700P. So at least you'll all have good info and pics of 5shot groups at 100m. I'll only chrono the accurate loads. So if you have one of the following rifles and are interested, stay tuned.
    Thanks again Mike and Sully.

    N150 has been my goto powder for my .308. I shoot 44.6 grains behind a 175 grain Nosler custom Competition.
    I haven't been able to get my new chrono to the range yet. However I have taken it to the 1000 yard line with the Santa Margarita gun club on Camp Pendleton at range 117 with good results.

    Before I switched to a heavier bullet I shot 46 grains of N150 behind a 155 Scenar. I would have kept using the scenar but I had 8 pounds of N150 on hand so it was easier to switch to a heavier bullet than dump 8 pounds of powder to switch to a faster one. I can tell you that 155's will make the competition cry with either N140 or Varget.. the 175 grain Nosler CC's are gave me better results with N150 being a slower powder.
