I thought you might like to see my 65 gr. bullet stuffed into a case. The OAL is not right, but you can see that this will be a coyote walloper. It's beside a 45 gr. JSP What a monster!

Edited to add: The finished weight will be between 64 and 65 grains. Different 22 cases mean tiny differences are introduced into the bullets. I always sort my bullets by headstamp, and after assembly, by weight. The bullets will always be within 0.5 grain of each other. ex: 64.5 to 65.0 grains.

Looks like a dog stopper for sure!

I'm still thinking about those 53gr you had available...

That nose profile reminds me of something...?

Looks good, would be an excellent long range bullet in the 22-250.

The design is carried over from my .314 bullets.

Base Borden decided to cancel work for the morning, to give the snow clearing people time to clean the roads and parking lots. I am somewhat confused as to why they did not plow overnight, but I suspect that the federal budget had something to do with it. Half a day (3 hrs actually) wasn't worth going back for, so I took this afternoon off to work in my shop. I will be putting these bullets on my site within the next dew days. I have to polish them up and take some pix.

This! Quite curious to try these.

Went to your site and see that the heavier bullets are for lower velocity rifles. May have to order some before spring to try in the duece.

so after reading your ".224 bullets made from 22 RF cases" page I have to ask, do these bullets perform like the Hornady SPSX with their thin jacket?
Any thoughts as to how those 65gr will fly out of a 1-9" barrel?
I shoot 55gr SPSX right around 3000fps right now and wind drift is a big issue.
I like the idea of those 65gr at 3000-3200
when will they be available?

just read your thread "I bought a 223 on the weekend" at CGS and see you were looking for a 1-9" for the 65gr...this bodes well... ;D

The bullets are sorted according to weight, so I spent most of the afternoon staring at a scale.

All the rimfire jacketed bullets have a velocity maximum of approx. 3200 fps, according to the bullet die manufacturer. From what I've seen over the years, rifling twist is more of a factor with this type of bullet. It's more important than velocity. If they are spun too fast, they fly apart. All bullets do, but the thinner RF jackets will let go at lower velocities. Some commercial bullets still carry a velocity maximum because they are constructed with a thinner jacket.

According to acquaintances in the US who make this bullet weight, rimfire jacketed bullets can be pushed to 3400 fps or so with slower twist barrels - 1 in 12 or 1 in 14. I don't have a 22-250 or similar to confirm this, but have no reason to doubt them. RPM is what rips apart bullets. 1 in 9 barrels will stabilize the 65 grain bullet. The bullet is 0.730 inches long, plus or minus a few thou.

I had to get another 223, to verify velocities. I say this because my preliminary workups for the 65 grain bullet indicated that I can push it to approx. 3100 fps from the 223. Last night I was testing the feeding of the 65s and they work fine. For the Axis, it appears that 2.230 inches will be the COAL for cartridges loaded with the 65 grain bullet.

WRT availability, I am confident that they will be available within the next week. I have some blems made from RF cases, some 52 and 66 grain bullets made from J4 competition jackets, as well as the new 60 & 65 grain bullets I've been experimenting with.

When the blems are gone, I'll make .224 diameter 60 and 65 grain bullets. Down the line, I'd like to try some 65 grain 6mm bullets. I have a 6x45mm and a 243 Win to use as test rifles.
