Re: 22-250 Ackley loads with a 1-14 Twist

Remingtonman_25_06,

I have shot enough 1-14 twist 22 cal rifles that did not shoot the 55 gr tipped bullets accurately to come to the conclusion that many will not properly stabilize these longer conventional 22 cal bullets.

That said, I have also seen reports identical to yours that at times they shoot these bullets very well.

In nearly all of the cases I have witnessed where a large 22 cal rifle would not shoot the tipped 55 gr bullets were with factory rifles. Perhaps the twists on these rifles were a bit slower then 1-14.

In all cases there was never a bullet that profiled on target, only that groups opened up dramatically compared to the 50, 52 and even 55 gr HP or SP bullets. Again this leads me to assume its the length of the bullet with the tipped 55 gr pills that is the cause.

When you say "BT" do you mean boattail of Ballistic Tip. I have yet to see any 22-250 or 220 swift not shoot a 55 gr boattail SP or HP accurately and the 55 gr FMJs are also generally very accurate as they are not as long as the tipped 55 gr pills.

Again, you never know until you get bullets in the air. Give them a try and see what happens.

I haven't tested any 55g Bal Tips out of my dads Ruger Target 22-250 to know if it will shoot them. It has a 1 in 14 as well. He shoots the 40g right now, but wants to switch to the 50 or 55. When I say BT I mean ballistic tips. I guess I should be more specific. I like the 55g bal tip @3925fps out of my swift the best.

Thanks for clearifying that. I think your dad would fall in love with the 50 gr pills over the 40s. That is if they shoot as well.

A 55 gr pill at near 4K fps is a serious load for sure!!

Re: 22-250 Ackley loads with a 1-14 Twist

I have one load in a 60 grain partition in 220 swift that is showing real merit in my stock 700 VSSF. The load is wimpy and was only put together as a " lets see what it will do" load. I can't for the life of me find my notes on the velocity but the average speed from memory was 3463 over ten shots. I used H414 win cases win primers, all brass was once fired neck sized only, had flash holes and primer pockets done. Remington says a 1 in 14" twist but with out measuring who knows? and for me it is no big deal. My current results with this rifle in other bullet weights have shown me that accuracy with 40 50 and 55 grain bullets has been the best at close to or max listed velocity's The only thing done to this rifle is trigger work thats it, and I am more than pleased whith what I have ( did I mention I bought it brand new on a closing sale for half of its regular price?) This rifle loves IMR 4064 with the 50 grn Vmax and it is the most accurate load mostly in the .3's for 5 shots at 3921 fps ave if I do may part at 100 yds. Next closest is 50 grn B tips with H414 at .4's with an average of 4060 fps. 55 Grn B tips are in the .6's with H 414 but no chrony readings and the loads are warm. I have lots of room to work on the 60 part load powder wise and I would not be suprised that it will be less than a .5 load with some tweeking. Gee wizz I sure do like this rifle it shoots better than I do and fits like a glove and gives me back my sanity after a long week. Here is my first attempt to post a picture in my first post after lurking for a fair bit on this site.

60 grn part 10 shots at 100 yds with out poi adjustment from current zero load. This rifle for 2005 took 192 Wood chucks at various ranges with excellent splatter effect.

I sorta can already hear the advice of shoot'em and find out, but when I get home I don't imagine I will have much time for experimentation. The main use of this gun is going to be for ground squirrels and chucks out to 6-700yds(hopefully). Thank you in advance!
in a 14 twist barrel your kinda limited to a small few 55 grain bullets and mostly 50 grain and lighter stuff. The Hornaday 55 grain V-max will stabalize, but the Nosler normally will not. The 53 grain V-max will not, but the 50 grain will. Not sure about a Nosler 50 grain bullet. What you should be looking for are bullets with a B/C in the low two's. Forget the 60 grain bullets in most cases. But if you want to try them, then the Nosler partition would be your best to try
