What am I doing wrong?

[MulePacker]

For the person who is having the problem AFTER seating the bullet.
You seating die is screwed down too far. IF you are trying to crimp be sure the bullet has a crimping groove and the bullet is seated to put the crimp in the groove. Then do not crimp as much. You are distorting the case usually where the taper from the body to the neck starts.
If you need some help PM me.

thank you Sir! I'll try it

No trouble. We all learn from our mistakes. That is how I learned that one. I also no longer crimp any rifles brass and do not have problems in any type of actions.
PM me if you need any help. I miss SLO. Went to Cal Poly in the 1970's. It sure has changed as has the town.

There is good advice above.

Try to chamber a resized case before priming, filling with powder or seating a bullet. If it fits, then your problem is not with the seating die.

Also, if your range picked up brass was shot in a machinegun, then the brass may be much larger than normal, and may require a small based sizing die.

For a non-carbide die (e.g. rifle full length), you're supposed to raise the ram up, screw down the resizing die until it hits the shellholder, lower then ram, then screw *DOWN* the resizing die another quarter turn or so. This means the ram is camming into the die. This ensures you resize the body fully.

With a carbide die, you set the die so it barely kisses the shellholder or screw it back up so it's maybe a business card thickness away from the shellholder. This is because the carbide can chip or crack if it impacts the press ram.

This is the proper instructions. This is also what I do. I learned the hard way like yourself. I use small base dies from RCBS and adjust as directed. It will work fine. Use this method on all your auto-rifle case sizing.

Well I wanted to apologize to everyone here who told me what to do the first time. This whole time I kept looking at the bullet seating instructions (in regards how to seat the die) versus the sizing instructions. all my brass is now fitting and I'm not receiving any hangups.

No problem glad you got it right now. Never load 100+ rounds for your 1st time before you know you have everything right.

Well I'm having kinda the same issue with my .308 bolt action marlin.

When I drive the bolt, it starts to get tighter the last 1/4" of loading the round into the rifle. I put the resizing die AS low as it will go.

Resized 1 brass, and checked JUST the brass in my rifle. seemed like a perfect fit.

Seated a bullet at 2.75 and I came across the same problem I started with. Tight fit!

Confused..

I dont think I need a case gage, because the case is fine, but i try to seat the bullet at it starts getting tight in my rifle. I dont understand because the max load length is 2.82 something.. and I'm just under that...

May be an issue with a tight rifle? It only has about 60 rounds through it..?

Over crimping will buckle the case enough hat it wil not go into battery lessen crimp and try again.

Nice ownership. Too rare. What have you learned?

[hambam105]

Germz showed a lot of promise by owning-up.

I reloaded for years without a single case gauge. Now I have a case gauge for every caliber I reload for. I think many reloaders don't know how to use one so they don't see the importance of the tool. Oh well.
