Stuck Cases 22-250

I'm getting stuck cases,I'm assuming due to over pressure.I may be wrong though.They chamber and extract perfectly without being fired.Factory ammo performs fine,Remington and Hornady anyhow.I loaded 34.4 grains of IMR 4895 with a 55 grain bullet.By the online manual and my book I'm close to minimum load.Half a grain over actually.This gun came from a freind that shot 34.5 grains with a 55 grain bullet,same powder.So I thought it is my scale.So I weighed bullets.Two different manufacturers came up 2.4 grains high in weight.To me they are not giving me free lead.So the scale may read high 2.4 grains.That means even though I have stuck cases I'm actually only charging the case at 32.1 grains.That is under the minimum.Any ideas or is my thinking wrong?I already tried loading the oal to factory specs.If that was the problem I would think an unfired case would be hard to extract.

Bob Seger,till it shines.

Re: Stuck Cases 22-250

Try zeroing you scale if that doesn't work calibrate it. You can buy a kit to do so. Below minimum charges can cause high pressures, hence stuck cases.

Re: Stuck Cases 22-250

IF I recall correctly, a friend of mine had a similar problem, and ended up having to load the bullets higher on the neck so they were barely crimped on to reduce pressure. I don't if that helps, I think he was either using a .222 Rem or a 22-250, and loaded them down which helped with accuracy issues on that gun/load.

Well, sometimes you eat the bear, and sometimes, well, he eats you, so the Dude must abide!

Re: Stuck Cases 22-250

The difference in the weight of the loaded rounds may be due to differences in the case thickness or case brass. First give your chamber a good cleaning. Then check your COL, Rour finished round may be too long and touching the lands thereby resulting in higher pressures.

Are you weighing each powder charge? Are you bumping your powder measure handle on the up and down strokes to get all of the powder out? You may be light charging one round and the heavy charging the following round.

{there's validty in this council....but not in the above}

Re: Stuck Cases 22-250

Where are you getting the load data. Is it someones "pet load"? In the manuals that I checked show you load of 34.4gr. of IMR4895 on the upper end of the data. The starting loads are down around 31 grs.

Unless you are using the exact same component's/lot's as your friend did, you should still start lower and work up.

As others have said, verify your scale weights.

Good luck, Tony

I dont doubt that for a second. It is also not the first time that I have seen a large variation in a starting load.
I double checked a few written manuals that I have.

22-250 55gr bullet IMR4895

Hodgdon: Start 32.0gr, Max 34.0gr
Hornaday: Start 31.4gr, Max 34.6gr
Nosler: Start 30.0gr, Max 34.0gr
Speer: Start 31.0gr, Max 35.ogr
Sierra: Start 31.9gr, Max 35.5gr

Good luck, Tony

Re: Stuck Cases 22-250

Wanna here something even better.....

Chris Hodgdon gave me a load to start... .243 winchester
87 v-max Hornady
H4350 42 start 43 max
95 BT Nosler
39 start 41 max

I saw the same load in My Hornady manual it the start is 39 for the v-max. But Chris said start at 42 grains... OOOOk.

But I needs to buy some H4350.... LOL
