I bought some new unprimed brass from remington for a 22-250 I shoot a compressed charge of 42 gr h-380. The brass would not take all of the powder 42grs, but all of my already shot brass takes it ok so i ended up loading 38 grs for another gun has anybody ever had this happen. Is it because the brass is not fire formed yet or what??
 
I have a speer manaul that says 38 grs to 42 grs. 42 grs being a compressed charge I have looked at the case and there are no signs of to much presure i am shooting a 52 gr sierra match king bullet
 
You can get a drop tube like Jason said or use a powder with less volume required. I've used 380 in 223, but never tried it for 22-250. I started using Varget in the 22-250, I've never looked back. I like to find powder volume to fill case but not compress, that's just me. I have compressed loads before, but they never performed as well in my rifles.
I have several manuals including Speer, but use my personal log/load book for loading now. I seldom look in manuals.

Take care,

42grns would only work with 40grn and lighter bullets, I have a load that I run 40.8grns of h380 with a 50grn bullet,its very accurate however its very edgy if the temps are over 40 degrees I get a sticky bolt and flattened primer, this load is also nearly 1grn over max. due to the temp sensitivity of h380 I have switched to RL 15, and am now going to try IMR 4007, H380 also looks like its not a good choice for super light bullet in the 22-250 for speed it looks like RL 7 or RL15 look like better choices. also I don't see a point in shooting a bullet that light, a 50grn bullet at over 3800 will do great out to 400+
 
I use to shoot 42gr. of 380 with the 40 gr.nosler ballistic tip.Crony said 4100 fps.It did ok,but alot of stress on the gun and brass.Fireform brass will hold more powder because its blown out to your guns chamber.Rumor has it thst Jameson helped develope H-380.55gr.bullet & 38gr.powder was the ultimate in accuracy for the 22-250.Thats why Hodgens named it 38.0..... This is the load that I use in my ruger for years.It has never let me down
 
I use 36.5 grains of H380 in my 22-250. Nothing else is as accurate (3/4" at 100 yards). I started using H380 due to good ol Gerry Blair. He recommended it back in the mid 80's in The Trapper. I've tried heavier loads up to 41 grains but to no avail. IMHO, there is no need to hot rod the 22-250. I've waylaid yotes at over 400 yards and 50 grain V-max's with great results. Who can ask for more?

I am not trying to hot rod nor am i a velocity freak this does not appeal to me, but I have 3 22-250 and 2 of them shoot 2 grs under the max load this gun that i am talking about will not shoot very good unless you put 42 grs h-380 pushing a 52 gr bullet believe me I have tried 3 different powders and 4 different types of bullet wieghts. This is the load that this gun likes. But lets not get off the subject which is I thought it was odd that the new unprimed brass did not allow me to fill it 42 grs of powder when the old brass did. Thanks for the info
 
I guess the same reason any new brass want hold more than recommened powder weights. The brass and neck gets streched and never goes back to exactly the same. DO you trim your necks everytime...... if not that would be a good reason why. I wouldnt risk hurting myself or my gun for a 1/2 group when Im sure you can get a inch group with a lot less powder weights and maybe different bullets. If not get a new powder.

Apparently you didn't notice that the subject quickly became your safety...not a subject that most gun nuts will "get off".
New cases that have not been fired typically have rounded shoulders and minimum body width because they have not formed to your chamber dimensions. Once fired they will take on those dimensions and allow for more space inside
(they get bigger).
