22-250 accuracte load trouble

Shane I think I can help

Shane, I had trouble with my 220 swift. I backed off to reasonable speeds around 3600 fps. purchased a bullet comparator to check runout, a micrometer tomeasuure neck thickness. shot 100 rounds through and selected a few pet brass.(35 out of 100 or so) loded the pets up and ran them through the dial indicator to check bullet runout <.0015 selected the best of those. Chamber diameter at the neck and neck thickness of the case will govern the bullet seating preasure and give you consistant chamber pressure. Now you have spent about $400 and two weeks of your spare time. Your wife and your friends think you are a little nuts but the prarrie dogs' spy is running home with some terrible news! Let us know if it was worth it.

da fox,

one more thing,

in that $400 was a set of competition dies with interchangeable bushings for different neck thinknesses and near perfect neck runout.

ok im gonna try this in the morning - only because h380 was the only one i had out of the list -- 55 gr noslers ballistic tips and new win brass with win primers and a mix of 38 gr 40 gr and 41 gr i am going to shoot 5 of each and see what happens - now with this encore barrel 26in i had to run out col to 2.250 and this is a little longer than it should be but that is what the gauge said and that is almost touching so i will see what they do and i wont get barrel hot either lol - will post after i try it

hmmmm
..."55 gr noslers ballistic tips and new win brass with win primers and a mix of 38 gr 40 gr and 41 gr"....
I'd suggest you work up in smaller increments, like 36, 36.5, 37, etc.
More work and components, I know, but for one, it's safer, and for another, you may be passing right over the best load using such big jumps in the powder charge.

jack i forgot to mention i have already tried the 380 but i didnt use 55 grain i had been using smaller and the best i got was pretty good and i used 38.5 gr of 380 sort of in the middle but i will try the lighter loads as you suggested i will also try 36 and 36.5 and so on and see what happens - i will stck with the 55 gr bullet and i will try different powders when i go shopping

[scooterman27006]

well well in this case less is more-- ok i tried the 55 noslers with 36 to 41 of h380 and guess what 38 is the sweet spot but even though its longer than should be-- i went with a overall length of 2.250 with all of the loads and with the 38 grains its right on there it will keep it in a dime - no i didnt take the calipers down to target with me lol but 4 were in a dime 3 touching and the 5th out to the left a little but that may have been me and wind was off and on breezing a little - i am going to clean barrel good and load a bunch of these and watch for a crow - if this load proves itself with shooting the gun right out of safe with the first shot several times i believe i am gonna put it in the book as "best load" for the 22-250 encore oh forgot to mention i did moly the bullets and barrel long time ago so this is with moly treated stuff -

Every rifle I buy today, I take to the gunsmith before going to the range, to have it glass bedded, the barrel floated and the trigger lightened. Most of the factory rifles we buy today aren't worth diddley out of the box. I don't like spending the extra money on them but really see no way around it. Best wishes.

cal id shoot them first.

that one rifle out of 100 may suprise you and save you some cash.

ive floated barrels on just about every rifle ive ownded and bedded a few.

i do have one that hasnt recived anything other than some trigger grinding. barrel isnt floated, its not bedded. and is my best shooting rifle with reloads and pretty dang acurate shooting cheap factory stuff. this rifle cost me just the buying price. no investemnt other than time i spent stoneing the trigger.

I've allways had excellent accuracy using 35 gr of IMR4064 and 52 gr hp, bt match serrias.

a little trigger work might help and shoot 3 fast rounds, let cool for 15 minutes, then shoot 3 slow rounds about a minute between each shot and you will see what the gun likes. In everything you are trying, pick which bullet shoots the cloest group for you, then work on the powder.
