chamber lenght

is there a tool that i can measure my 22-250 chamber, to get the right measurement for reloads

Make up a dummy round to determine the length. Depending on bullet weight and shape this measurement will vary quite a bit and will depend on how long a throat your chamber has. All this won't matter much though if your magazine won't handle the length of a round that is set up for max COAL. It's probably best to make up a dummy round with the bullet you plan to use by partially sizing the neck of your brass so that the grip on the bullet after you seat it will move easily when you chamber the round (no powder or primer) and push the bolt forward and closed. That will push the bullet into the case and will tell you what the max overall length will be with the bullet seated into the lands. When you remove the dummy round you can measure it with a caliper and set up your seating die accordingly. Me personally, I like to set up my reloads with the bullet "kissing" the lands so long as the magizine length will allow it.

Yes, Hornady makes 2 tools, one for headspace and one for COAL

ok i took a new case with 60 grain vmax just started it in the press and then chambered the round, twice, length was 2.452, my lymans spec book shows 2.350 max,  how far back from the 2.452 would you suggest seating the bullet?

does 2.452 fit in you magazine???

2.33 is what mine is set at.

yes  2.452 is a good fit with new brass

and your bolt closes completely at 2.452???

is this a custom built rifle???

yes i bought it from a guy who used it for match shooting, i just like to shoot coyotes with it

ah now we are making sense. go ahead and load em up as long as you want. that rifle is made to shoot long bullets. probably built on a long action rem700 long action too.

I doubt that very much, pyro.

doubt what?

Doubt that a 22-250 would be built on a long action.

really? i bet it would be if it was a competition rifle like he says it is. thats how those guys make up for the long heavy bullets they like to use.

look at the 6.5x55, its the same story. i know a few guys that do that with the .257 roberts and the 7x57 as well. its not that uncommon for people to build rifles that are normally based on a short action and use a long action rifle platform. that way they can use those berger type bullets and seat them way out and still fit in the magazine.

If it is a custom rifle then there are 2 other things he needs to find out.
