Jimmy Knox (JLK bullets) is making a 90 grain javelin but it requires a 1-6.5" twist to spin it. By all indications, it's doing very well at 1000 yard service rifle applications.

What kind of rifle are you shooting? Do you know the barrel twist? Most .22-250s, not all, are 1 in 14" twist. They'll shoot up to a 60gr. bullet well but nothing larger. It makes quite a bit of difference in terms of accuracy. Best wishes.
