52gr amax in 1:10 twist

1-10 twist 22-250?? That is an odd combo. With a 10 twist you should be able to shoot bullets up to 65 grains.
I'd say it's marginal, but you'll probably manage OK. Depending on what you load them to and the resulting MV, you'll be stressing the jacket heavily. I've had them blow up in flight in a .223 1-8" twist barrel at around 3,300 fps. That equates to 297,000 rpm spin rate. Assuming you loaded them to 3,600 fps your 1-10" twist gives them a bit less - 259,000 rpm.
A lot depends on other factors though such as barrel quality and wear, degree of fouling in the bore, barrel and ambient temperature. My 223 barrel (Lilja) didn't like some Hornady bullets and I used to lose the occasional 75gn HPBT Match in flight (but not the 75gn A-Max!). The problem was always more likely to appear in hot weather - I could shoot light match bullets OK on cool days. Since we rarely see really hot weather in the UK, this may be more of a problem for you depending on where you are.
A 22-250 with a 1-10" twist stabilises 68-70gn match bullets such as the 69gn Sierra and may offer a better combination than the 52gn bullets depending on what you plan to use the load for of course.
