300wsm resizing problem ??

I got to were the shell holder was contacting the die it was still hard to chamber
I know this will cause shoulder set back ,and headspace problems which leads to case separation.
I have had 4 Tikkas and more rifles in other brands, and never had this problem with any of them
so now is it the dies not rezing it down for a oversized chamber?maybe a set of small base dies would work ,say some thing that's used for semi autos?

You do have to set the shoulder back 0.001 to 0.002", if you are running out of headspace, which appears to be the case. Setting it back that much is not going to lead to case stretching and case head separation. You can do this by taking 0.001" off the shell holder at a time and trying the case in your gun.

I do have a question that you may have answered before. Do the fired but unsized cases fit back in the gun? If they do, but a sized case does not, then the die is causing the problem.

Edit: I see you have said that unsized but fired cases do fit the gun. That confirms the die is causing the problem, and you would not gain anything with a small base die. I am very sure you are squeezing the shoulder ahead, and you are running tight headspace, that is making it hard to close the bolt.

The correct way to do this is to use a Hornady Headspace Gauge tool to measure the length of the cartridge to the shoulder. The routine is to measure a fired case. and then push the shoulder back until the gauge measures 0.001" shorter. But, from what you describe you will still have to lap the shell holder to bump the shoulder, if you have the die hard on the shell holder, and can't get any more bump.

Redding sells a set of Competition Shellholders with stepped amounts taken off. However, probably cheaper and faster to buy an inexpensive Lee and just lap it down on 240 Wet or Dry.

Ron AKA, this is what I mean about your BS postings and not knowing what you are talking about. The Redding competition shell holders will not push the case into the die as far as a standard shell holder.

The deck hight of a normal shell holder is.125 and the +.002 competition shell holder deck height is .127, +.004 = .129, +.006 = .131 etc. Now with your 50 years of reloading experience how is pushing the case from .002 to .010 "LESS" into the die going to bump the shoulder back more.

If you don't know know what you are talking about just keep your mouth shut and not add more confusion and stupidity to the posting. :bangHead:
 
OP, when you push the case all the way in the die and initially have the die touching the shell holder, you need to look when your ram is all the way up with a case being sized in the die and see if you can see light between the shell holder and the die. I suspect that all you need is another 1/8 - 1/4 turn in on your die and your problem will be solved. I have over 100 sets of RCBS dies and have never had a die not capable of sizing a cartridge enough to chamber. Some do take a hefty bump on the shell holder to fit some rifles but I have never had to shave a shell holder when using RCBS dies.

bep51.........just ignore old sunray there, he just keeps making himself look stupid, thread after thread after thread.........50 years of loading experience? Those must be internet years...........:rolleyes::rolleyes:

The problem is we have younger inexperienced reloaders here that actually believe his BS. And if thats not bad enough when I go over to Accurateshooter.com and he is trying to pass himself off as a world class competitive shooter.

Below is Ron's AKA "50 year old" brown Redding scale and even as old as it is look how clean and shiny it is. He must wax and polish it before he weighs each case and powder charge.

This is very common with the .300wsm and the Tikka/Sako rifles. You need to use a very good lube like lee or imperial sizing wax first to ensure no stuck cases. Spray lube and you will have a stuck case with the .300wsm trust me. Make sure some gets on the case mouth as well. Second you need to have your gun handy and keep trying your sized cases after incrementally turning your die down a little at a time until it closes nicely. There is a fine line between not closing, closing and to far. Also I found my Lee anniversary press flexed to much so my rock chucker had to be used to get a nice fit. This issue caused a lot of grief for me in the beginning. I actually ripped the expander ball clean off the threads of my rcbs die due to insufficient lube on the mouth. Oddly enough my Weatherby vanguard had not such issues and shot better than the Tikka. Hope this helps

I think his problem is that he is already contacting the shell holder, so there is no more adjustment left to turn the die down. It seems to me his specific die is not bumping the shoulder enough for his specific chamber. Long die in combination with a shorter chamber potentially.

I don't recall that he is having issues with a case stuck in the die. I use STP oil additive and it works fine for lube on the big magnum cases. I put a very thin coat on every cartridge. I don't like to use a die lube on the ID of the neck though, and just use a bore brush dipped in powdered graphite to clean/lube the inside of the neck.
 
Read the post by 243winxb at the link below to see how to measure a shell holder or shell plate.

There are many variations in the manufacture of shell holders and the first check you make is with the rear of your vernier calipers.

NOTE, if you ever see any posts by 243winxb on the net "READ THEM" he knows a great deal about reloading.
 
so I bought a rcbs shell holder and it works like a charm ,it seems to be a little thinner then the hornady one I was using .
Thanks guys for all the help

Good that you got a solution. It is too bad that the manufacturers can't get their act together and maintain a standard. The shell holders appear interchangeable, but it seems there are differences. I believe they are supposed to be 0.125" from the face to the level where the cartridge base sits. However, I just measured a couple of mine and one was 0.1230" (Lyman) and the other about 0.1225" (Lee?).
