22-250 and H335 questions

The speer reloading manual 13 and 14 have the max load of 55 grain spitzers with H335 using a magnum primer at 36 grains.

Website info yields 33 grains...kind of strange how it's lower than the max laoding of bullet weights above and below it.

Also, the hodgdon manual just calls for large rifle primers.

45 GR. BAR XBT Hodgdon H335 .224" 2.340" 31.5 3593 41,400 CUP 34.5 3908 48,500 CUP
50 GR. SIE SP Hodgdon H335 .224" 2.350" 31.5 3519 44,400 CUP 34.5 3753 48,700 CUP
52 GR. HDY A-MAX Hodgdon H335 .224" 2.350" 31.0 3417 43,200 CUP 33.5 3657 49,200 CUP
55 GR. SPR SP Hodgdon H335 .224" 2.350" 30.5 3400 44,400 CUP 33.0 3589 51,100 CUP
60 GR. HDY V-MAX Hodgdon H335 .224" 2.350" 31.5 3272 50,800 PSI 34.0 3494 61,400 PSI

So after working up some incremental loads I have some 55 grain hp boat tail sierra game kings with 33.5 grains of h335 in them.

Should I shoot them or pull them?

If you have already worked up to the 33.5gr from lower charges without issues like hard or sticky bolt lift, or cratered primers indicating excessive pressures, then I see no reason to pull the bullets. If that's the case, try a few to see if they exhibit any pressure signs. One rifle may show pressure signs, and another show nothing but normal loads.
Many rifles can handle the higher pressures, and the Tikka is a strong Mauser style action.

You have the manual telling you that 36gr is maximum if that is any comfort. If you don't feel comfortable, then you can always pull them.

It may have to do with the actual length of the bullet (not loaded round). Using the same grain weight of a bullet that is physically longer will raise pressure since the bullet is seated deeper into the case.

Hard to say with seeing the bullets themselves. If you're wondering, call or e-mail your bullet manufacturer. Everything else is a guess IMO.

Another thought is that many loads ask for Magnum primers with ball powder like H335, which would bump up the load as if it had more powder. I wouldn't have any problem shooting that, I've loaded 34 grains H335 under Remington 55-gr SP's for 22-250 in a Savage HBVSS.
