.338 Norma load data needed

waveslayer · March 25, 2014, 01:21 PM

I am having a hard time finding good load data for the 338 Norma.

I will be using 300 SMK's.
What powder and suggested OAL

Have you tried Norma? The only way I was able to find load information for Berger bullets with my powders was by sending them an E-Mail. They got back to me the next day and I was satisfied with the results. I had wanted to try the 190gr VLD in a 300WBY. They also gave coal data, and said that the coal in some custom target rifles might not fit my rifles magazine and that I may have to load them singly. Good luck.

I did try Norma. They gave me the same data that is on their website for their powders.

There are sources of powder burn rate comparison. My loading software contains a list.(RCBS.load) This is an expensive disc, but there may be comparisons available on line.

I know your frustration, I reload for 6.5-284 Norma and have had to contact powder manufacturers for info on new powders,ie, RL17 and they had no data for 6.5-284, which isn't even listed in the Speer or Hornaday manuals. Alliant told me that RL 17 was comparable in burn rate to H4350, but developed higher pressure. Again good luck.

Sometimes I wish I chosen a more mainstream cartridge, but the performance is impressive when you finally get it right with a Norma.

You might have to break down and buy a suitable powder from Norma.

handlerer2, Berger has loading data for the 6.5x284 Norma OAL 3.228" also Nolser has data for their bullet OAL max 3.228" but they tested 2.980".
