N570, RL26, RL33 for 195grn Berger?

[Popapi]

Which powder and why? My STW shoots high .2s to mid .3s consistant with RL26 at or around 3020fps with 28" Proof. A good friend told me that RL26 was trash. I do have 5lb of N570 and a 1lb of RL33. What do you guys use with good results wit the 195. My group's have never been shot lower than 80 degrees being this rifle was just built. All shooting has been achieved at over 80 degrees. Wondering would I have a shift negative in performance at lower temperatures. Thanks in advance.

rl26 availability is trash... The powder has seemed just fine to me the bit I've worked with it. Shoot it yourself to see on the temp swing issue, but I use rl25 in my 7stw (s) and have for 15 years with no issues.

I would suggest an actual test.... I realize that requires getting to the altitude and temperature in question. Unless you know the critics are very good at analyzing a situation, let actual data speak and ignore the armchair experts

RL26 haven't been a problem acquiring for me. If I run out I'll try the RL25....thanks for chiming in sir!

Start around 76 grains and work up to 80 to 81 My best was at 78 pressure at 81 for me

You should be able to find a thread in here that I posted with all my reloading info
