Re: 22-250 build help

I hear you on TOF. There is a point where high BC without adequate speed is not the best compromise.
I just noticed a mistake in my last post too. A .1 mph change in wind speed was not moving my bullet .7 MOA, but 7/10 of an inch. Slight difference there!

Forgot! WIND. Mother nature don't care about ballistics, she never moves the wind at a constant speed. We can have 4 mph on wind meter at bench and our flags at 1 miles flying straight out, then in a moments notice, the flags dead to the ground.............Ballistics calculator can't work up a load for me on that one................I could never tell a difference of 1 or 2 moa at 1 mile, just 12 to 20 feet difference on impact.

Re: 22-250 build help

My personal opinion concerning the 22-250 compared to the 22-120 Ackley Improved is that the Ackley version is far superior. It has more punch than the standard version and the brass lasts a lot longer. On the twist side of things, I like the old 1 in 14 using projectiles up to 55 grainers. You can run much lower weight projectiles and crank them up to ridiculous speeds. Try the Barnes 36 grain Varmint Grenades.

I am not a fan of using heavy 224 calibre projectiles. I really can't see the point of choosing a fast twist 22-250AI and using heavy projectiles. It eliminates the fun of shooting really fast lower weight projectiles.
If you want heavier projectiles in the 70 and 90 grain weight range, my suggestion would be to go with a larger calibre like a .243 or .257.

On a side note, I have a 22-250AI and I also have a .220 Wilson Arrow. The Arrow is slightly ahead on speed and accuracy. Both are custom Mausers fitted with very heavy #7 profile 26" barrels.

Just my 2 cents worth.

Re: 22-250 build help

Sold a couple saddles today and ended up with a new prairie dog hunting ranch that is said to be loaded with them. Looks like more work for the 22-250!

"I am not a fan of using heavy 224 calibre projectiles. I really can't see the point of choosing a fast twist 22-250AI and using heavy projectiles. It eliminates the fun of shooting really fast lower weight projectiles."

While I enjoy the impact of a fast moving bullet on varmints, I also like to shoot long. I plan to have my '250 rebarreled with a fast twist 26" tube to shoot the heavy VLD's. Most of the places I have been shooting PD's there have not been large numbers, but there have been lots of shots further than what the 52 grain bullets are up to on a consistent basis. But in the back of my head is a small voice that keeps whispering 6XC and Berger hunting VLD's.

Re: 22-250 build help

Try fast twist with 40 gr V-Max or 52 A-Max bullets. I have used my 1-9 twist in 22-243 A.I. with 40's up to 4800 fps and they rip the heck out of a PD. I would go 1-10 with short throat and have some fun.
Years ago SSS Fred Moore told me at that time he didn't think you could over rotate a bullet. Well you can these new bullets, the 40 V-Max. Because now my same rifle with the 1-9 will spin bullets at 4800 and they don't stay together anymore. Also the 30 V-Max always blew up at 5200 fps......Now I can on spin them around 4400 fps otherwise they split into 2 impact points or just leave a silver grey cloud.
