I'm sold on the Blitz Kings but I've also shot the Nosler Custom Competition 52 grainers and they shoot extremely well.
So, if it ain't broke, don't try to fix it; just shoot the bts and be happy!
It's interesting to find out what ALL your gun likes, at least that's why I try different loads

Re: 14 twist wont stabilize 55 gr bullets

I just read this post and am delighted to see I am not the only one who has not been pleased with 22-250s and a 1-14 twist. So many coyote hunters act like the 22-250 can do no wrong but I disagree. My experience is my first shot is above bullseye and the next one below. The next shots always did the same. High then low, high then low. Nothing ever hit center. I tried various rifles, bullets and powder with the same result. Berger 52 gr and R15 were the best I tried but still less than impressive. Both of my 223s with 1-12 twist seem to shoot anything I load them with so I have no plans of ever owning another 22-250. I would be curious to know how a 1-12 twist works in a 22-250. My lesson with 22-250s is that velocity was irrelevant when I couldnt hit anything.

Re: 14 twist wont stabilize 55 gr bullets

Factory barrels are hit and miss. The 14 twist was probably intended for 40 grain bullets at 4000fps at max 200 yards on groundhogs. In addition, the bedding on Remington rifles is atrocious. With a real 9 twist, a 22-250 might be interesting but for sure bullet choices for the 243 are better.

A 243 is my favorite coyote caliber. I havent shot the tightest of groups with one but I have never done much load development either. I find 243s to be very consistent and none that I own have ever left me scratching my head. If I miss with my rem 700 vls it is nobodys fault but mine. I hadnt really dealt with a 223 much until a few years but the more I use one the more I like them.

Re: 14 twist wont stabilize 55 gr bullets

the barrel twist rate is the important factor here, and not really wether it's a 22-250 or a .223 or .222. Have not shot a 14 twist 22-250 in many moons, but the last one I shot did half inch groups with bagged Remington 55 grain bullets that you buy in bulk! Have no idea what the load was, but guess it was around 3400fps. The rifle was a 700 BDL with a 12x scope on it. All my
22-250's have a 12 twist barrel, so can't compair the three that I own right now with a 14 twist rifle. But on the otherhand I have a .222 with a 14 twist barrel and at least two .223's with the 14 twist barrel. The .222 will punch .60" groups all day long in a hand gun (15" barrel @ 2700fps). I think that one is good for about .50" groups if I'd just setdown and work up a serious handload. My Remington 700 has a 20" barrel in .223. Has only seen about five different bullets in it's life span, and the worst was about 3/4" groups (all my groups are five shot). Like I said I use the Hornaday Vmax for groups in the mid fours. (3270fps). The barrel is junk, but the chamber is right. My hand loads are 27.5 grains of BLC2 with the bullet seated .002"/.003" off the lands. Cases for these loads are from Hornaday. Bullet runout typically is .0013"/.0015". It's simply not rocket science here. But for an experiment, I'd try the Hornaday 52 grain Amax bullet. It has a B/C thats about .23, and is a boat tail style. The 53 grain Vmax will not work in a 14 twist all that well as it has a .27 B/C.

I think I'd have the barrel recrowned by somebody that really knows their business, and start all over. The first hint of trouble is that the boat tail shot better.

Re: 14 twist wont stabilize 55 gr bullets

Maybe I missed it but did anyone mention seating depth? If you left your seating depth die set the same does not mean your seating two different bullets at the same depth. Most dies seat off a location other then the ogive, so where you may have be .010 off with the 55 grain bullets. You could be .015 off with the 50's. Just something else to check.

Also I shoot a 220 swift with a 14 twist and it stays at or below moa out to 300 yards with Nosler ballistic tip BT's.

Re: 14 twist wont stabilize 55 gr bullets

I have owned a few 22-250's in my day, and I'm sure they were all 1-14 twist. I have never had issues with stabilization with anything up to 55 grains. My present set up is using a 55 grain Berger match bullet. Load info is , 35.0-8208-55 Berger match@ 2.464 OAL. Typical groups are in the .2-, .3 area. The 8208 powder is amazing. That is all I shoot in this rifle, and my 308 too!
