150 gr Winchester sp power point in 300 blk

[Viking painter]

So I got 500 blem 150gr Winchester sp power point bullets in .308 from RMR a while back for like $.17 ea and planned on using them for plinking rounds. They are a total mess as far as the length and position of the cannelure so I have to sort and constantly adjust the seating due to maintain consistent seating depth, just a pain in the ass and won’t be buying these again. Loaded them with 16.9 gr of lil gun and maintained around 97-98% load density to not compress it and make the es and sd go wacko like lil gun likes to do. Took them out and fired the first 20 through the chronograph and was shocked when I saw the numbers! 10.3” ba Hanson barrel, pistol gas, aero upper and lower with Lahar 30 suppressor, 1892 fps avg/es of 7/ sd of3! This is the best numbers I’ve ever seen with lil gun and with a total POS bullet and twice fired formed a USA brass and ginex srp so totally a “ IDGAF” type load. 3/4” groups at 80 yds. I wonder if these will will expand sufficiently enough to put a coyote or maybe even a black tail down at shorter range. BTW, no major pressure signs with these except slightly flat primers but ginex primers seem to flatten even with lighter loads, must have thinner cups the the usual cci 450 or cci 41. Anyone have any experience with these projectiles in 300 blk?

I guess that's as good as any way to shoot up less than stellar bullets.

Ya, they’re taking up space where much prettier bullets go,haha. I can’t believe the es/sd numbers from these, those are vihtavori numbers I get from my creedmoor! Gonna try them on a boar and see if they’ll expand and bust through thick skin, the pp always worked great for 30-06 for me but of course going much faster.

That's part of what got me into 300BLK. I had a bunch of free Hornady 150gr soft points that my .308's weren't very fond of.

These are a complete mess as far as cannelure placement and bullet length, I didn’t even want to waste the primers and powder on them but they kept looking at me begging to disappear,lol. So I used the worst components I had and they had match grade es/sd numbers and excellent accuracy, blew me away! Must be the barrel, it shoots everything pretty good, even subs are 1 1/2-1” accuracy at 100 yds. I am going to try a ba Hanson 5.56 barrel and see if they are as accurate as this one.

My 9" Ballistic Advantage 300BLK barrel is very accurate, and it will take longer loaded ammo. My PSA JAKL and Ruger American Ranch in 300BLK are picky about how long I can load ammo for them.

My ballistic advantage 10.3” will take longer loads as well, must be the way they cut the throats in them. I have the ba Hanson premium ss and it’s just as accurate with my normal vmax load as a match 5.56 barrel I have to 150-200 yds. After that, we know which one wins,lol. After I added the Lahar 30 suppressor to it not too long ago, it picked up another .25-.4” of accuracy, it’s shooting.3-.75” at 100 yds all day! It’s just a real tack driver! My 7.5” cheap palmetto blk is surprisingly accurate too but nothing compared to the aero/ballistic advantage build.

And now you can't replicate it because those bullets can't be had anymore?

But as you say, if it's the barrel, no worries there.

I got about 400 left so I guess I better enjoy them. The barrel is extremely accurate with pretty much everything I’ve tried, I have a few thousand 150 gr federal fusions that go in the Winchesters spot.
