.22-250

[northernchris]

Hi
i am looking to load the .22-250 with some Hornady 69HPBT in my Styer SGG with 1-14 twist do you think it will stabilise with this twist rate?I will use H380 has anybody got a starting load to suit the above bullet/powder combo?

I would say not a chance in haties but I have been wrong before. Give them a try to find out but do not expect much. From what I have seen, even a 1-12 is marginal with these bullets in many cases and a 1-10 would be about right.

Yuup highly unlikely.

I tryed some 65gr sierra game kings in a 1-12" twist and the holes looked oblong at 300ish yds.Wide-open load of h-380.
Leonard over at huntmasters has got the 64gr bergers to fly -although w/a 1-12". Mike

I wouldn't waste my time. Lerch tried everything in his 1-12" 22-250 and nothing larger than a 55 gr would stabilize.

northernchris, If it is genuinely a 1 in 14 twist barrel then it has no chance of stabilising in your 22/250.

About 20 years ago, when the Hornady 68 grain HPBT, and Sierra 69 grain HPBT became available in Oz, I built up a .220 Swift AI. I took my gunsmith's advice, and chose a 1 in 12 twist barrel, but despite reaching 3,700 fps, every projectile keyholed into the 100 yard target.

So a 69 grain Sierra at about 3,250 fps out of a 22/250 with a 1 in 14 twist barrel has no chance whatsoever.

I have used the 69 grain Sierra extensively in my 22/250AI with a 1 in 10 twist barrel, and at velocities ranging from about 2,800 fps through to 3,450 fps, there has not been a hint of a keyhole, and accuracy has usually been 0.5moa or better. Hope that is of some help. Brian.

Use a Nosler 55 grain Bal Tip over IMR4895 w/WLR primer.
