Help with .308 subsonic loads

[Fixr]

I have been looking around but I can't find any good published information on subsonic reloading data so I have a few questions. 1- Do you have a source for published subsonic reloading data? 2- My rifle has a 26" 1 in 11 twist barrel, has anyone had any success with 220 grain RN bullets, most of what I have read says they won't spin fast enough. 3- What are you successfully shooting .308 subsonic with?

Thanks for any help.

Chris

For hunting try 10 grs., give or take a few tenths, of trailboss and 170 gr. Hornady 30-30 bullet.

Use pistol primers.

Thanks Dave, that's interesting about the primers. I have heard of using large rifle magnum primers but not pistol primers. Can you tell what the benefits are for the different primers?

Reduced velocity spread but with that being said neck tension also comes into play. It's all about doing the same thing each round with subs. Anneal, size, expand over a mandrel and load.
