Excellent! Thanks. I'm in process of starting workup on a new .308. My goto for the .308w is IMR4064. It always seems to get me really close.
Starting powder selection for load development

I would pick 3 and run ladders with the 3 and let that decide.
Theres got to be alot load data out there, pick the 3 people seem to use the most with what bullet you wanna use.
Not in any particular order if you have them but Varget, H4895 and 4064

What do you use and what calibers do you use them for? When you first start out load development.

Most of my loads are straight out of the reloading manual. Start midway and work up by .3 or .4 and find a sweet spot. Some manuals lists a preferred powder but I've tried H4350 in numerous calibers due to having an abundance of that one. Looking at my list of powders (45) I can pick and chose.
22-250, but there good powders for 308.
I dont get sold on 1 powder, usually there is a top 2 or 3 that work but each gun is different

I have a technique that follows this philosophy, the powder's in the top 3 in almost every manual providing the top velocities are the most efficient for that case capacity. If any one of them are hard to come by or not available, it gets dropped from the list and another powder is chosen. I search both bullet and powder manuals, sometimes they agree and, other times they do not.
I also have a good knowledge of what powder is going to be suitable for a particular case size, ie.
17/22/223 Start with 748, Benchmark, 8208.
22-250/22-250AI Start with H4895, Varget, H4350.
260/7-08/308 Start with Varget, 760, H4350.
25-06/270/30-06/338-06 Start with H4350/760/H1000/Retumbo (depending on bore size)
All belted magnums. Start with H1000/RE25.
Large magnums RUM/NMI/Rigby based. Start with Retumbo, US869, H50BMG.
Larger than this. US869, H50BMG, RE50.
I don't have any real world data for VV powders, so I didn't include them, it's not available here.
Cheers.

For what caliber? Are these starting powders?
