Wilson Seater Die conundrum

I wanted to get a wilson seater die in 7mm Saum. I went to the sinclairs website and ordered one, seemed easy enough.

http://www.sinclairintl.com/product/11017/s

The die arrived and it was a 300 saum. I then checked the wilson website and they do not actually make a 7mm saum only the 300 saum. I enquired at Wilsons a few months ago and they told me this. When I saw 7mm saum listed on sinclairs I wrongly assumed they must have started making them:rolleyes:.

It seems sinclairs have a goof up on their website as they currently list only a 7mmsaum, not the 300.

As I see it I have two options One is to buy a seater die blank and get it reamed to 7mm saum. The other is to use the 300 saum die to seat 7mm saum bullets. Would this work?

I would guess that all wilson seaters have a degree of slop in the neck area to allow for different neck thicknesses, and for people that don't neck turn.
The rest of the case and the shoulder would be supported in the 300 saum as the dimensions are the same.

It is interesting that Wilson make both 7mm wsm and 300 wsm seaters which makes me a bit leary of using the 300 saum die. I am fussy and will go the custom die route if that is the better option.

Cheers in advance

Well possibly, I have just emailed them, will be interested to hear what they say. I know that Wilson are not making custom dies at present, so it is hard to see what they could do for me and the problem here really lies at Sinclairs with the botch up on the website.
 
My two cents....get a 7mm blank from Wilson and use your finish reamer. If you can't get your hands on one right now don't be afraid of the Redding Competition Bullet Seater, the next best thing in my opion and not hardened so you can ream it to if you wish...buy it small and ream it!

I usually do one of each just so I have them both. Sometimes a certian bullet will like one of them more than the other.

Your loaded round concentricity runnout will be alot more using the 300 saum die than a 7mm saum die.

If this is for a hunting application it probably wont matter, but if for a competition application you would be better off with a properly dimensioned 7mm seating die for a 7mm bullet..............Don

Using the 300 die will seat the bullets, but it sort of seems to me you defeat the whole purpose of using this type die in the first place if you go this route.

I agree with Tony

If it were me, I'd send the 300 die back, get a blank and ream it with the chamber reamer. That way you know exactly what you have.
 
My experience and theory

regarding the inconsistent OAL's I have experienced with Wilson seater dies: I believe the the lever on the Benchrest Arbor presses we use aren't long enough to properly seat bullets in cases that have been used a bit if one is using quite a bit of neck tension and the same may be trye for other "Factory Like" chamberings. I think that is why my threaded seaters will give more consistent OAL's, the press lever to crunch in the bullets is longer thus mo power.

I think you found the missing link. In an earlier thread you were sayin' that your seating measurements were inconsistent and I was sayin' that it just couldn't be. Certainly, if the case hangs up a bit in the die the seating would be different...and serious leverage would perhaps correct the matter.
 
I could see case hangup causing it but why would a case hangup??? I always thought it was because of the difference in geometry of the seating spindle. While some bullets work better in the Wilson others work better in the Redding for me. For me it is down to two issues, bullet shape and bullet runout.

Pete, are you sorting the bullets for runout first? Is the problem always with the same brand/weight/shape bullet?
