  • 30-06 COL question....

    I'm loading 57.5 grs. IMR 4350 behind a 180 BTS Sierra with a col of 3.345...I didn't see any reloading material that suggested a load that long, but it shoots cloverleaf 3 shot groups in my rifle...I guess my question is as long as the bullet is off the rifling and fits in the mag. I should be good to go...right..?

    Sounds like you've figured it out. OAL is limited by the individual throat of the rifle and the length of the magazine box; so long as your ammo fits both you are good for that rifle. A factor to keep in mind is that your ammo will not feed and function in all other 30/06 rifles. This is not a problem so long as you keep this ammo segregated for this particualr rifle.

        That's key if there are others in your household of if anyone else is likely to get hold of your loads. You've got the essentials down pat, but I'd go ahead and label your boxes with info about which rifle the loads are intended for so there will be no confusion 10 years down the road when you discover a leftover box on the dusty back of a shelf somewhere.

          Resizing also

          Factors other than the overall length may keep the rounds from feeding in other rifles also. Unless you full length resize with small base dies rounds shot in a Winchester for example may not chamber in a Remington.

          Just something to consider if you have multiple rifles in the same caliber.

            Just my $.02, but after thousands and thousands of reloads, I've never had an issue in a bolt action rifle with FL sized ammo. I've seen issues in lever actions and semi-auto rifles with FL sizing, but never in a bolt action (with the ammo used in the same gun or from rifle to rifle). I understand it can happen, but I certainly wouldn't recommend using a small base die just in case...

              I agree on trying before resorting to SB dies. But I HAVE had problems with over-long bullet seating.

              The most notable occurred long ago when a buddy and I were using our 06's and light hollowpoints to bust rockchucks and ground squirrels in a western state. Mine was outshooting his so far out that it was really frustrating for him. He asked to try some of my loads, and I didn't hesitate since they were nowhere near max.

              He dropped a round into the action and cycled it forward into the chamber, then decided he should go ahead and load the magazine, and ejected the shell to do that. Except when he pulled back on the bolt, all this powder came spilling out and an empty case dropped on our shooting mat. And he was left with a bullet lodged in the throat. It was a loooong walk back to the truck for a cleaning rod to remove it, and we both learned a little more about caution in the process. I'm not too worried that anything would have blown up due to the moderate load, but can't rule it out either. But in any case, bullet seating depth is variable from rifle to rifle, even when the cases chamber fine.

                Resizing

                I've had issues with .30-06 FL sized cases in bolt rifles esp. the older Remington 700s which tended to have tighter chambers. However, I've reloaded with brass from both commerical and military surplus rifles including M-1s, '03s, M98s, FN1949s, Madsens, etc. which tend to have more generous tolerances than commerical rifles.

                Best solution is to try the rounds in the firearms ahead of time BUT if you want to make certain that the rounds will chamber in any '06 including semi-autos, pumps, and lever guns the best option is to go with the small base dies - then you know that they will chamber.

                I'm not certain that the small base dies really do any harm in a hunting rifle. If the headspace is fine the cases will fail at the neck eventually and I've never been able to tell any different in accuracy between a FL sized round and one from SB dies. Sizing in the SB dies do require a bit more work and attention to lubing the cases prior to sizing however. Generally I size range brass in the SB dies and then use FL afterwards unless I run into an issue or I'm loading for possible use in future unknown rifles.

                  Do the SB dies size ONLY, the base, smaller than a regular FL sizing die, as the "Name" would indicate, or do they size smaller all the way around?

                    In my use of them over the years, my sense is that it's base only. Everything else is the same. It's only a few thou in that region just above the web, but it comes at a cost. I find that case life is reduced quite a bit, probably because the oversized chamber allows the case to swell a lot, then you're squeezing it back down further than "normal." That's complicated because this is all happening down close to the web where you really can't anneal, and therefore you get brass hardening, splits, and eventually even head seps if you're not alert. The need to use an SB die can be progressive. My current 250 only needs it on every 4th loading. My 25-35 needs it every second loading. Interesting enough neither my Savage or Winny 358's need it at all. Had a 99 in 308 that needed it every single time. And my 99 in 284 has never needed it.

                    The only guns I've seen that really needed SB dies were Savage levers and Winny levers and semi's. For some reason (luck?) I've never owned a Remmy pump or semi that needed one. Never seen it in a bolt either. Only time I've had bolt "problems" was when neck sizing for one rifle and inadvertently moving the cases over to another rifle. FL sizing fixed that, following which I could go back to neck sizing for that particular rifle.

                      Best I can tell only the base is sized more - basically down to factory specs.

                      I would only use them if needed or in the event the rounds need to postively work in some unknown gun.

                      You can sometimes get rounds to chamber OK with standard dies if you adjust the die far enough down in the press so that you get hard interference with the shell holder at full stroke. RCBS recommends this in some instances if you have minimum headspace and/or a tight chamber.

                        A small base die sizes to minimum specs so as to chamber easily in any SAAMI chamber. Factory specs reside upon a spectrum allowing for variation in manufacturing tolerances. FL sizing dies resize within specs, but normally not minimum specs as that needlessly overworks the brass in most circumstances.

                            case life

                            Except for case head seperations where headspace was an issue my cases - regardless of what die I use to size them - eventually fail due to split necks or loose primer pockets.

                            What kind of premature case failures have you had from the use of small base dies?

                              I'll let him speak for himself, but I expect case life to be cut in half or worse due to incipient head seps with SB dies, compared to standard dies or neck sizing. Just the way it works.

                              Near as I can reconstruct I started reloading in 1958. Could have been 1959, but for sure it was before 1960. Lotta rifles, reloading dies and cases under the bridge since then. And they're all different.

                              You experience doesn't make his wrong.
