I haven't smoked or dyed the neck and shoulder yet. I will try that this weekend and see if is by chance contacting the shoulder. I would assume it's not because I'm not sizing the entire neck but I am sizing 90% of the neck. Since the bushing is somewhat rounded it may be contacting the...

I have the Redding Type S Bushing Neck Sizer Die that does not bump the shoulder as seen here: Redding Type S Bushing Neck Sizer Die 7mm Remington Magnum - MidwayUSA I should have mentioned that I am not neck sizing the entire neck so that it aligns better in my chamber, therefor it is not...

I have a Redding FL body die and the Type S bushing style neck sizer die. Using my body die I have been bumping my 7mm RM's shoulder .002 after it became snug in the chamber. I measure the headspace with a hornady l-n-l gauge after I bump the shoulder and it is exactly .002. Then I proceed to...

My load is: 72.5 grains of Retumbo Fed 215 gm nosler brass (trimmed) 168 grain bergers (sorted) bump shoulder .002 load .002 off of lands (jump) I clean my barrel every 20 rounds or so and usually clean the chamber. The firing pin strikes were fine last several week but were cratered last time...

I do trim my brass after every firing. I also sort my bullets first by length from base to ogive then by bearing surface. I am usually very meticulous about cleaning my gun thoroughly. I did not, however, use a chamber mop last time and I will check to make sure the chamber is clean. It usually...

I'm using a redding body die to bump the shoulder back. That may have tightened it up a bit? And come to think of it I did just buy another can of Retumbo which was used for these loads. It went from zero pressure signs at 72.5 grains to major pressure with the same load. It scares me that a...

We were shooting out of the shade (the brass was cold) and my second shot out of the barrel showed bad ejector marks and the bolt was very difficult to lift. Obviously I'm backing off of 72.5 by at least a grain but was just curious as to what could have caused this sudden jump in pressure...

Need your help. Been doing some ladder testing with my 7 mm RM and found a load that had a low vertical dispersion at 1,000 yards. The load showed no pressure signs and was developed in temps above 90. I shot the same load yesterday in 70 degree weather and my brass, primer, bolt showed major...

Very good info guys. I'll reset the die then I'm going to check my shell holder and make sure it's not too thick. If I have to I'll grind the shell holder and then the die. Thanks again

I've been taking a few measurements and compared against saami spec. The 7 mm rem mag should have a headspace of 2.125 and my brass is getting tight at 2.121 which means my gunsmith may not have cut the chamber deep enough. I called redding and they said their tolerances are very tight on both...

Got it! Makes sense. Thanks for your help.

How should I take of the bottom of the die? Just sand it down? I did order the comp shell holders that are made in .002 increments - will those help?

Guys I need help on this on. I have a redding body die for my 7mm Rem Mag. When my headspace measures 2.122 it gets tough to close the bolt. I set the die up by screwing the die down until it contacts the top of the shell holder. I then tighten it down and run a lubed case through it. The...

168 gr bergers 64.4 gr of 4831 sc Nosler Brass fed215gm primers .005 into the lands. Shoots 1/2 moa for me in my 7 rem 700.

Both very good responses. I hadn't considered the length problems with the RUM although I think my smith could cut the chamber to match my bullet choice. I am leaning towards keeping the 7 RM. Maybe the extra 200 to 250 fps isn't worth all of the potential problems? Keep em coming. Hearing from...
