rcbs gold metal seater die vrs redding ?

[grizzlydueck]

I want to upgrade my performance out of my winchester 7wsm brass for example correct the run out -the rcbs comp dies are different from the gold metal but does anybody have any experience with the gold metal seater die and does it match the performance of the redding or other top comp dies ?
thanks so much for any info

"...does it match the performance of the redding or other top comp dies ?"

No. In fact ONLY Redding/Forster seaters with full length sleeves that align both the bullets and cases before seating starts offer an accuracy advantage over more conventional seaters and are worth the extra cost.

It's worth mentioning that no seater can make straight ammo in cases with out of line necks.

I agree with boomtube on this. He is spot on.

Pay particular attention to that last statement...

I would add that I've had pretty good success with Wilson hand dies and an arbor press. ...not sure how the other guys feel. But, I think they have a huge advantage in that you can easily tweak seating depth at the range.

I pretty much go the same route that you do. I'm also kinda odd in that I prefer the old style seater die to the new ones with micrometer on the Wilsons. I just use a metal shim under the head.

Now I'm a "garbage in-garbage out" kinda guy. I believe that if you start with good strait cases; the rest will fall in place. I use almost nothing but Forster seaters (threaded), but with three or four exceptions. Plus it's a given that no seater can straiten up a bad case! Most guys will inspect a case after resizing, and that's OK. But you really want to check it before resizing as well. Look for a bump or a hicky made by the extractor (rather common). I keep a small India Stone just to remove those bumps. A thousandth there really trigs out to some substantial numbers in a 3" long case.

One thing about the Forster seaters that alot of folks ignore is that they can order in a smaller caliber, and ream it out with their chamber reamer. An example would be a 6mmx45mm round. You can start with a .222 and literally make the seater fit your chamber. Sinclair used to sell all the spare parts for Forster dies (guess they still do?)

I have the RCBS Gold Medal and the RCBS Comp Seater



Both let you insert the bullet in the side into an opening and it falls down in it's collet which holds it in line with the neck of the case (WARNING: very addictive, once you get used to it you will hate using the others). The bullet starts straight and is easier to seat, less stress on the neck brass. I also have some Redding Competition Seaters which I get when I can't find one of the RCBS Comp Seaters and it takes more force to start the bullet seating than with the RCBS.

The Gold Medal RCBS differs in 3 ways from the RCBS Comp seater

1. The bullet collet covers the neck, bears on the shoulder and comes down 1/4" down the case body (the Comp seater only covers the neck and shoulder)
2. The seating stem is stainless and floats up and down unlike the Comp seater which has a fixed black seating stem
3. The Gold Medal somehow will hold the bullet and not let it fall through. IOW if you drop a bullet in the side window of the Comp seater it will fall through unless you have raised the ram high enough to hold it in place (convenient but not necessarily necessary)

Personally I have chased concentricity extensively and I can tell no difference in the final product between the Redding Competition Seater and the RCBS Competition Seater and I love the side window.

YMMV

I have two redding competition sets and two rcbs completion seating dies.

The rcbs is easy to use dropping the bullet into the window and does a good job. My redding seater does much better with runout due to the case being supported during the process. What I found that eliminates the most runout is the bushing style neck sizers because they provide even tension around the entire case neck. I inspect my brass before and after sizing either discarding or using as a fouling shot.

I do prefer the redding dies much more. I use lapua brass if I can get it in that caliber because I discard fewer pieces of brass. I use nosler for my 300 rum with great results. I get more runout when I use Remington brass.

I get .001-.002 runout commonly with the redding always correct down to .001 or smaller. I get .003-.005 with the the rcbs, but still get a good many in the .001-.002 range. I measure contrencity using both Sinclair and hornady but I correct using the hornady (I do get some small differences in measurement between the two). If I can ever get a redding competition seater for my 45-110 sharps I would be in reloading heaven.

Saying all that I am happy with results of both but prefer redding. I got the rcbs on sale and at the time needed to pinch some pennies.
