Lyman 310 tool

#1 Post by PeterN »

I was wondering if anyone has one of these and if they ever use it. I have one with a set of .308 dies that I got from a fellow club member who was selling off some stuff for little money that was new as he had never used it. I have had a little play with it but not used it to load any rounds. I also got one from ebay that was described as complete with .303 dies. I didn't look at the photos close enough and there were some .303 stuff but some that wasn't. The priming chamber and seating die were there but not the sizing die and expanding die. There was a .313 bullet sizing die and two decapping dies. The adapter die that came with it was the number 10 and not the number 5 for .303. The number 10 is for .45/70 and also 7.62x54R. It wasn't too much money so not too fussed. I had a go at priming a few .303 cases with it and it worked fine. I have recently seen a Lyman tru-line press and various dies for sale on ebay for £150 but that is too much for me for a casual purchase. That particular seller always has out of focus photos on his listing. I messaged him once about it but he doesn't seem to care.
I noticed a set of tongs and .38 special dies have just sold for £100 on ebay. Are they really worth that much?
Regards
Peter.

Back in the day I had a set with dies for, I think .38 S&W. It was a handy little tool for that type of round but I would need to be in some sort of survival situation before I would want to use one now, especially for rifle calibres. I still have a 310 tool somewhere but no dies - the tool body I have now is not quite the same as my original set.

Well, I had a go at loading some .308 rounds with the Lyman 310 tool. The cases were already deprimed but I went through the neck size, neck expand, prime and bullet seating using the tong tool. All seemed to work OK. I checked a sample of the cases to see if they would chamber OK before I loaded them as they are going to be fired in the same rifle. I will find out tomorrow if they work OK.

I have a Lee hand press that, at times, I've found very useful. When developing loads and I've got to the fine tuning stage, I load a batch, all exactly the same and at maximum length so they will just chamber. Shoot five, then, with a micro seating die in the Lee press, seat the next five 20 thou deeper, shoot them, seat the next five deeper again, hopefully seeing the group shrink then open again as you go through the optimum seating depth.
You could use the 310 tool in the same way.

I really like the 310 system and have them in over a dozen of the calibres I shoot.

The hand tool is fine if you only want a handful for the next days stalk.

I have a Lyman Tru-line junior four station turret press made for the 310 dies, a little bit short on leverage for some of the larger rifle cases like the 30-06 even although the system is neck size only.

The good news is Lyman make 310 bushings so they can be used in ordinary presses.

The rounds I loaded worked fine. A couple of sighters and then eight consecutive 5s and Vs on the 200 yard NRA target at 200 yards. That'll do for me.
