I've been working up loads for my 30-30 Win Contender using a Speer bullet designed for 300 Blackout velocities. I caught wind of this bullet over on http://www.300blktalk.com/forum. There are 14 pages of posts concerning this bullet, and I think I read each and every one of them. The velocities they were getting from 16 inch rifle barrels was in the 2100 fps range, which just happens to be about the same velocities listed in reloading manuals for the 30-30 Win in a 14 inch barrel. One gentleman even expansion tested them down to 1400 fps impact velocity in gel, and it still expanded, not just upset the nose a little. I started by establishing an overall length to touch the lands and then backed off .025 inch. Used Fed 210 primers, because that is what I have the most of, and decided on Leverevolution powder. I performed the accuracy and expansion tests at 100 yards, and was happy with my results. Need to try it on a critter now to be certain it works.








The bullet is a Speer 150 grain #308150BLKGDB, and after passing through 3 one gallon jugs of water and caught in a box of rags, had a retained weight of 147.3 grains and expanded to .700 inch. It accomplished this with a muzzle speed of only 2160 fps. I'm going to go with the 37.5 grain load and call it good.

That looks like it will work. I would guess from the description, this bullet is a 150 grain, for a 300 BlackOut, Gold Dot, and Bonded.

I have been working with the Hornady 135 FTX bullet in the 30-30AI. So far I have not done any expansion testing. It to is a popular 300 BO bullet.

The 300 BO has been great for lower velocity 30 cal pistol loads. I found that 458 socom did the same for 458 cal pistol loads. Now if we get a 6.5 & 7 mm and a few other choice calibers we would be sitting pretty.

That looks very good Mech! Please keep us posted.

Looks like you found a winning combination. Hope you can report back in the future how well it worked on game. Thanks for sharing!
