just got me a Ruger No. 1 Varminter in .22-250 with a 1:14 twist, I know the optimum load is a 55 gr. does anyone out there shoot the 60 grain partiton and what do you think of it in this rifle/caliber?

Just off the cuff, with that slow a twist I'd figure that the optimum range of bullet weights would be from 40 grains up to maybe the 55s at most. Sure, try 60, but cross your fingers. 50-grain bullets would work well on jackrabbits and coyotes.

A 60 gr bullet is right on the ragged edge for a 1-14 .22-250. I got excellent accuracy with Hornady 60 gr softpoints but the slightly longer hollowpoints were just wild.

The Nosler 60 gr partition is nearly as long as that hollowpoint and I would not expect it to be well stabilized.

you will need to stick to flat based bullets to keep the bullet length as short as possible.
The longer boattail bullets will generally be the type that are more prone to be under-stabilized.
I believe the 63gr Sierra will work in that twist.

a 1:14 twist

It 'may' stabilize 'some' of the heavier bullets but....the 40gr. weight is what was intended for that twist, we just went through this at the shop, and Ruger will tell you that the heavier bullets were not around when they(Ruger) decided on the 14 twist....

Beats me, just passing that on, the best way to find out....load up some 60 grainers and give it a whrull!


...and please, let us know what you find, I know I could use some accurate, actual data and findings from an end user instead of the nominal BS you'll get from most of the manufacturers...not that Ruger offered or gave BS, because they did not, but...

I tried it in my Ruger MK77II with 60gr. partions with RL 15 and Varget powders and I got marginal results with this slow twist rate. This gun will shot lights-out with any 50-55gr, bullet. I was trying for a small deer load and could tell the bullets were losing stabilization.

This would have been news to Jerry Gebby and J. Bushnell Smith about 75 years ago.
They thought a 14 twist was about right for 50 - 55 grain bullets in a .250 Savage case necked down to .224". MY Ruger is most accurate with 52 gr SMKs, which falls right in there.

About all .22 centerfires from .218 Bee up had 14 twist barrels for decades until the Army stirred things up with the second lot of M16s. Standard bullet weights ran from 46 to 55 grains, in proportion to case capacity; except for the .220 Swift which got a 48 grain bullet so they could pump the velocity up to 4000 fps..

I put a Weaver Grand Slam 3.5 x 10 x 50 on it Sat., bore sightd and am gonna sight it in monday morning with 55 grain Hornady and then give a report, then try some 60 gr. partition later. the Grand Slam is awesome, changed my mind from the Leupold I was gonna put on it. Art, I was chairman of the Watermelon Thump Beer Garden for years til last year. I remember an Ellerene Stair down by the golf course and a Patti Stair, must be your kin folk, good people, havent seen em in yeaers. good to talk to ya.

Want to be polite without laughing, but have to ask, were 40 grain loads around then either?

Don't shoot the messenger, this....this is why I refer to it as BS from the manufacturer.

I don't really know IF 40 grainers were around way back then, maybe in experimental stuff that never made it to the shops, or maybe tried and not liked, so forgotten...I can't tell you, but the question comes up now and again and we'll be happy to call the manufacturer, while the customer listens and put the question to them!

It seems that ,IF the twist (1/14") WAS made specifically for the 40 grain bullets...the 40 grain bullets would have been around and available, right? like I said manufacturer BS!

When the 22-250 was introduced by Remington in 1965, it had the 1in14" twist and the factory loads were 50gr and 55gr bullets. The lighter and heavier factory loads came much later.
The 40gr-45gr bullets were relegated to the smaller cases like the hornet and Bee in factory loads at that time.

My 22-250 prefers bullets lighter than 55grs. It will shoot them about 1-2MOA while sub 55grs bullets are almost all sub MOA.
