Has anyone used the Forster carbide 3-in-1 case mouth cutter on 30BR brass, after neck turning? If so, what were your results?

I'm trying to determine whether or not it can be used on thin walled necks or if it was designed for more of a thick-necked hunting cartridge versus a turned benchrest cartridge. Thanks for your response.
 
Forster turning

My farther and I used forster neck turning gear for the field varminters. The 222 and the 243 as well as the 25/06. Not tight necks but a lot tighter than a factory tube. When it came to turning the PPC brass I found it difficult to adjust it very small amounts. Like a few tenthousandths. Nor did it seem to leave a particularly smooth finish no matter how many times I passed the cutter over the surface. Fine for general clean up of field rifle brass but I use the K&M system now for all the brass.

I use the RCBS 3 in 1 trim to length.
It does a fins job with one pass operation.Thin neck 0.082
Requirers a special case holder for 220 Russian brass for < than $10.00.
Its faster than the Wilson/Sinclair doing all steps at once (Trimming to length, outside and inside chamfer)
Not what you asked but similar trimmer I think.--They also have a power adapter for electric drill--I dont use this so can't comment.

I really like it. My neck chamfers are now more consistent than I can do with one of the hand rocket tools. It is bit of a pain to adjust, but I don't see the need to hold tenths. I just want them all to be the SAME.

Andy, are you talking about mouth cutting, or neck turning???

Cheers,

Keith,

From the "I don't know but it can't hurt" column: Jim Hardy, a former 1-K benchrest shooter & then Palma shooter, did some testing. Don't know the setup, just his conclusions.

Jim felt the quality of the chamfer was important, it was for more than just not scaring the bullet base when seating. I *think* he used the Wilson tool, there is a different "crank" you can get with inside deburring cutters. This works on the inside of the neck only.

The second thing Jim found was a 45-degree chamfer works better with flat base bullets, the 30-degree works better with bottails. "Better" in terms of performance on the target, but I don't know his testing procedure, sample size, statistics, etc. Jim's a pretty sharp guy, though.

For the original poster: can you get the Forester with different degree cutters?

Oh, found it. It's 14-degree only. Might be worth further testing on what angle's best for what bullet,...

Neck turning. I am not likely to confuse the two.

To make it absolutely clear, I'm talking about a 3 in 1 case "trimmer" [mouth cutter as Foster describes it] that trims, deburrs and chamfers necks, that in my situation as a 6PPC and 30BR user, would be used on case necks that have been previously "turned" thin.
 
Charles,
Interesting results from Jim Hardy. I am at a loss as to how to explain it.

Someone with some tool grinding skill could make cutters with different angles for the Forster. They are just little pieces of flat plate.

I like that the Forster (and the RCBS) gauges the cut off of the neck, rather than the body like the Wilson. With the Wilson, if the neck is not concentric with the body, the chamfer will not be concentric with the neck.

I have been using the "Forster 3 in 1 case trimmer" to trim, deburr, and chamfer my Lapua brass for a couple years now. The brass is 6mm BR that has been necked up to 30 BR, and the necks turned to about .010". The tool works great and I have recommended it to a couple fellow shooters that have called to thank me for bringing it to their attention.

Keith;
I'm lost.
You said, "gauges the cut off of the neck, rather than the body like the Wilson".
I can adjust length of the case by adjusting the collar on the crank shaft. And so, it seems to me that the three way cutter, which I don't have, would still adjust the length of the case and the inside chamfer the same way. It is only the outside chamfer that is adjustable based on the thickness of the neck.
When this thread began on Tuesday I immediately called Forster and spoke to Robert Ruch, CFO, and mentioned this to him. I'm surprised Forster hasn't responded. One thing I took from our conversation was that you should not mess with and adjust the pilot as that will throw the whole process out of adjustment. The other thing was that the trim to length and inside chamfer cutter was one and the same. Makes sense to me. If you get the tool out of adjustment or alignment for $12.00 they will bring it back to factory spec and send it back to you.

Francis,
You are correct. The length cut is gauged off the base. But the chamfer cuts are based off the mandrel that is inserted into the neck.

Yeah, I read the warnings about adjusting the cutters. Good advise for those not mechanically inclined, but for anyone with any machining experience, it isn't hard to do. I will have to steer clear of Robert, since he may want to slap me on the wrist!:eek:

Cheers,
Keith
 
Kind-of on the same topic. Wilson makes a trimming tool and a chamfering "reamer" - do they make a deburring tool? I like the wilson chamfering tool because it stops in the same spot each time - just wondering if they made a deburring tool that does the same thing? Thanks in advance.
