Dunno 'bout "optimum", but mine puts 50 grain Nosler BT's into one hole at 100 yards. 38.0 of H-380, WW cases, Federal LR primers. Seated .010 off
 
About 55 grains is going to be the upper limit with a 1-14in twist 22-250. I have the same rifle in a B&C medalist stock, definitely one of my favorites.
 
Heaviest weight should be around 55 grains, but every rifle is different.
 
The heaviest is going to be the 63 grain Sierra Semi-Pointed bullet.

It was especially designed for 1/14 .220 Swift and 22-250 wildcats 50 years ago.

My longest coyote kill was 517 yards with that bullet in a 1/14 22-250 I built a year before the 22-250 became a commercial caliber in 1965 when Remington introduced the commercial version of the old wildcat.

You will likely have good luck with any 40 - 55 grain bullet in a 1/14 twist barrel.

Just not anything heavier in Spitzer or BTHP then a 55.

The only 60+ bullet that will likely give good accuracy is the Sierra 63 grain Semi-Pointed I mentioned, which is very short for it's weight.

The 70 grain Speer isn't bad, but it is pretty blunt.

The 14 twist was standard in .22 centerfires for many years, when they were varmint rifles and a 55 grain spitzer was about the maximum.
The Army went smallbore and screwed everything up with heavier and heavier bullets, requiring faster and faster twist; leading people to think that a 14 twist was useless.
 
Ain't useless, but I will take a deer with a 77 grain expanding bullet. I'd prefer not to take one with a 50 grain! :eek:

It's much more accurate to say that the Army smallbore focus has led to optimizing accuracy and effect at long distance.

I have a similar Remington and load 55 VMax for varmints and 55 Sierra Game Kings for deer and hogs. They shoot into the same hole, so no need to adjust the scope. Might be an option for you...

after 300yds maybe a 22-250 is almost useless with all the powder being burned. My 223 with 1x8 twist and 80 grain AMAX at 2950 will shoot flatter then 22-250. I was in a ditch off to the side of a target at 600 yds and watched light 22 bullets tumble in the dust before the target like someone threw them. I put a 1x8 barrel on a ruger target 25-06 chambered it in 22-250 and pushed the 80 grain AMAX 3250 and shot 2/12 groups at 450 yds with the first load

Bullet

I shoot a 60 grain Nosler Partition bullet from my Remington 788 22/250. Same hole every shat at 100 yards. Longest shot was a bottle off a fence post at 600 yards. It took me 5 shots on a windy day to smash it.
 
My .22-250 is also a Rem. M700 ADL with 1/14" twist.

It is my most accurate rifle. It shoots frequent 1-hole groups (5-shots @ 100yds) with Sierra 50gr (40.0gr H380 or 35.0gr IMR4064 or RL15), and 55gr Sierra's and 39.0gr H380. BTW; it's getting 3,700fps w/55gr bullets....

It shoots well with 60gr Hornady PtSpt's, and 63gr Sierra Semi-pt. (3/4moa). I use 37.0gr H380 for ~3,500fps. I've taken deer with this rifle w/55,60, and 63gr bullets.
Not much difference, at ranges in excess of 200yds, the bullets completely penetrate. I've not yet recovered a 63gr from either the .22-250 or the various .223's I've shot deer with. It's the best "deer" bullet for the 1/14"twist .22-250 IMO.

My rifle however "gags" on 60gr Hornady V-max's (not unexpected) and "tosses" the 55gr V-max's into 1.5-2moa.... 65gr GameKings run likewise 1.5-2moa. But, I've not tried them at longer ranges to see if they'll "go to sleep" (stabilze) or conversely, start to tumble.
It's moot as I bought a large quantity of 60gr Hornady "blems", and have a enough supply of them to burn out the barrel, unless I start burning them up in an AR15.....

I'll take the accuracy with the 50-55's any day !!! They'll "do" for deer with decent shot placement.

Only "issue" with this rifle is that it isn't pleasant to carry any distance with the 6-24X 2lb scope attached....

I will add; during the '11 Georgia-Auburn game (half time and it was "ugley" for us.. -Auburn); I shot a doe in my front yard with the 60gr Hornady over 26.5gr of RL15 from my 16.5"bbl AR15. The forward raking shot hit the last rib, and was lodged under the hide on far shoulder after breaking the humerous. Bullet weighed 38.5gr with perfect mushroom and no jacket seperation. Deer ran 23yards and dropped. This the only 60gr Hornady I've recovered, and I estimate impact velocity to be ~2,900fps... Reasonable performance for a .22cf on deer.....

If I can get a 60 Nosler Partition to group in a 1/14 .223 barrel, you should be able to get one to shoot from your faster 22/250 with the same twist.
 
My Browning B-78 has a 1:14 twist also, and it absolutely loves Nosler 40 grain, flat base HPs. (bullet #17225). I was loading it pretty hot, but I backed the load off a bit to 35.0 grains of IMR4064 and got awesome accuracy.

Prior to trying that bullet, I had good luck with the Sierra 52/53 grain bullets.

I am not sure but I think when the bullet goes faster it might make it worse
 
I have had good luck and accuracy with Nosler 50gr ballstic tips, Winchester brass, CCI 200 primers and 37.0 gr of H380.
