Home Forums Reloading Big Game Rifles 60 grain NPT in a 1:14 twist 22-250

Anybody have any experience with this combo. Have a new Tikka I want to work up a deer load for and I have a few of these coming. Just worried about whether this twist rate will stabilize them. Also have some 53gr tsx coming so hoping either these or the NPTs will group well for me.

Also if anyone has any load suggestions using either of these bullets, I'm all ears.

I think this was up not long ago, but my .22-250 is a 1-14...with IMR4350 it will drive those bullets into small clover leafs...same with the 63 grain Serria...I used to old max load from the Serria book...Have shot that load in 3 barrels on my old .22-250..with the Serria..it was accurate in all three...only used the NPT in this last barrel...you may just have to try it..I would start with IMR 4350..it pretty well fills the case...

Nosler made the 60gr partition to work in the 1-14". Here is the general rule i use for my 22-250 with 1-14" - Bullets under .810" long work at 22-250 velocity.

Wouldn,t work in my m70 bullets hit the 25 yard target going
sideways. Think i was useing H380.

Would it be a reasonable assumption that if the 60gr NPT works, so will the 60gr NBT? They would be a little cheaper for target practice and should have a very similar trajectory.

My Swift shoots the 60gr. Partition's great with a 14" twist.

Tatelaw,

My 14 twist 22-250 shoots them fine, but not nearly as well as 50-55g target and varmint pills. I shot 3 loads last weekend in the 14 tw with the 60NPTs over H4895, H4350, and IMR4007SC and they went .75, .88, and .65. That should work just fine for deer.

Baltz is that for the 1:14 twist? I shoot Savage with their 1:12 and stay between 53gr (TSX) and 55gr bullets (VMAX). I was told by Barnes I would need a 1:10 to shoot their 55gr TTSX.

1-14" Copper bullets are very long for weight. A 55gr nosler ballistic tip is .810". Winchester 55gr FMJBT is .740". 70gr speer semi spitzer is .790". 64gr winchester power point is .805". 55gr sierra flat base spitzer is .715". remington 55gr flat base spitzer is .690". 40gr nosler ballistic tip is .696". A 60gr nosler ballistic tip is over .810". I think I read .900" so I would not even try them in my 1-14" 22-250. But they would work fine in my 1-9" 223. I shoot a lot of 64gr winchester power points out of my 22-250, cronograph shows 3364fps. I have shot the 60gr partition using the same exact load, I prefer the performance of the 64gr on game. The 60gr was very accurate

So Baltz, are you saying 50gr or 55gr NBT would be better for cheaper target practice?

I have shot 3 different 14 twist 22 250 and had excellent accuracy with the 64 pp. 2 of the rifles shoot the 60 partition well but the other (a REM 700 Sps) would not shoot the partition. I agree with the 64 pp performance on game. Two bears and a whitetail and exits on all three.

I tried them in my Rem 700 1-14 could not hit BIG target at 100 yards had to get withing 20 yards to hit target all were key holed. Shot fine in my 1-12 223.

22-250 1-14 near max load with H 4895

My 28", 1 in 14 Encore barrel does not shoot the 60gr Partition well. I've tried various powders and OALs with 100 bullets and could not attain better than 1.5" groups. It shoots various 45, 50, 52 and 55gr bullets .5 MOA consistently.

From what I've seen from other 22-250 rifles, 60gr and higher bullets are a crap shoot with a 1 in 14 twist.

I buy 64gr winchester power points in 500 lots from midway. I then use them to kill stuff. Deer-cougar-coyote and for practice. Other bullets end up just being shot at targets. I have 55gr ballistic tips loaded on the bench right now, for long range sight in. If they will hold 2" 300yrd consistancy I'll use them on my coyote/cougar trips. I do not shoot rats, So light bullets are pointless to me. If my rifle did not shoot the 64gr it would be down the road or rebarreled.
