Re: First time reloader... best expanding bullets for subsonic 300 blk?

They did indicate it would be subsonic, but I can call back and discuss further. They seem more than happy to discuss over the phone. Since I am not reloading yet though, I can only talk in theoreticals with them. I will use this data and call again.

Re: First time reloader... best expanding bullets for subsonic 300 blk?

FYI the guys at Rainier have suggested 10.5g of 1680 and an OAL of 2.135 to get the 180G HP bullet to expand. I wont be able to test this for a while but just thought I would leave it here for any of you that have the Rainier bullets. I am working on getting some distributors that carry these bullet...

Wow that Rainier looks like that AFTER impact? It looks like an un-fired round! :(

Re: First time reloader... best expanding bullets for subsonic 300 blk?

rainier wedge 180s RN or HP, palmetto projectiles 203 coated, berrys, leatherheads, are good subsonic plinking options Lehigh defense, Maker bullets, Outlaw State, and Blackout Bullets all make subsonic expanding bullets. The blackout bullets are the cheapest of the group at less than $0.50 a bulle...

Re: First time reloader... best expanding bullets for subsonic 300 blk?

Thanks for all of this discussion.. I will be re-reading a few times and seeing what is out there there is affordable to get started with. Two followup questions: 1. I see that Gemtech makes a popular 187GR subsonic that many on the forums have commented is a good hunting round. Is that true, and, i...

Re: First time reloader... best expanding bullets for subsonic 300 blk?

Do the 180gr Rainier bullets mentioned in a thread near this one expand much at sub speeds?

Re: First time reloader... best expanding bullets for subsonic 300 blk?

Yes the expansion was mainly for my use for HD. Small hunting uses would be secondary. I did not realize that decent expansion at sub speeds was so expensive!

So I guess I will need to find great bullet options for a HD load, both sub and supersonic, plus a plinking subsonic load. Thanks!

First time reloader... best expanding bullets for subsonic 300 blk?

I am about to embark on my first reloading experience ever, and plan to reload for subsonic 300 blk pretty much exclusively to start. My rifle uses a 10.3 BA Hanson barrel, Superlative arms adjustable pistol length gas system, and SiCo Omega. Home defense and general <100yards plinking and fun / var...
