Thread: Who still makes 0.223" diameter projectiles?

conclusion?

I think the Sierra #1385 40gr hp is the go. I think it will be worth trying without resizing down to .221"

If I can get a .24" group @25m to translate through to 1" at 100m, I'd be happy.

The soft point 45gr hornet #1210 was very good, but might be better with a lighter load as Hornets ain't really going 3400 fps! probably 100fps slower!

the hottest hornet load data I could see for 40gr was 2800fps so we're a fair bit ahead of that,
When you say .221" Sierra 40gr, did you size these down? if you did how did that go, if the .223" do shoot better it would probably be better to resize the .224 projectiles seeing as .223 seem to be harder to find.

I've got to clean and deprime all my brass today so will load up some more to test once they're all dry,
I'll test my loads at 25m to get a closer comparison to your numbers, also easier to see with the 4x scope
I'm going to retest the scope theory before I go and drop a bunch of money to buy a new one, so more results should coming soon.

I meant 't 1,000 fps slower, not 100 - typo.

The .221 were sized down from .224 using a push through die from CH Tool and Die in the USA.

I'll see if I can get some more of the .224" Sierra 40gr hp and try them unsized. I think the reason these were shooting well at .221 is the length - they are reasonably short.
I'll check all my brass for pressure signs and let you know if anything is a worry. The higher loads make the brass flow and the cases get longer and the necks thicker.

Parallax could be an issue for your scope - have you checked?

It'll be interesting to see what happens with the .224 projectiles in your rifle, I just finished cleaning out my suppressor after slipping and packing it with mud :/
Aside from the mud it was surprisingly dirty so I'm wondering if I might gain some accuracy from that, brass is all drying below the fireplace at the moment but should have some loaded up by tomorrow for testing,

Honestly don't know much about parallax, don't think my current scope is adjustable for it either, I'll do some googling and see what I can find on the topic.

IMO avoid parallex adj scopes. Just one more thing to go wrong.
Just get fixed parallex at abt 150 yards for centre fire rifle.

Hey Goose, I'm not suggesting you get a parallax adjustable scope.

Check your scope for parallax error - on some scopes, especially some cheaper ones, they can have significant parallax errors which will add to your issue.

Line your scope up with a target and then move your eye around to see if the crosshair moves in relation to the target - it shouldn't.

If you need glasses but adjust the eyepiece focus without your glasses on, this can cause a parallax error.
Discovered this myself, was about to throw a scope out. Readjusted for my glasses and the error went away.

I'll check against a target next time I'm out, I pretty much set the scope to 9x for anything over 40m so that could be the issue, the nikko being a fixed 4x would likely eliminate that?
