I have found that high quality ammunition can be load on a T-Press. It can be used as a single stage press or if the user chooses as a multi-stage press.
In fact my loading normally follows this path. When doing load development I load five loads, five rounds each progressive increasing the powder charge. A trip to the range to test the loads for safety, accuracy, and velocity. I might stop at load three (5 ea.) because it is the most suitable, and pull the bullets on loads four and five.
I next trim the brass, chamfer the mouth, inspect the case, and run a bent paper clip inside the case looking for case separation. The case is then de-primed and tossed into the tumbler. This is done with the Lee de-capping die, in residence in the T-Press; this die has worked without any addition adjustment on a number of cases.
Each case is given a quick visual inspect on removal from the case tumbler and is wiped of any residual dust from the tumbler, and the primer pocket is included in the inspection for cleaning material blocking the primer pocket. The case is then primed and placed in the loading block. I use a hand primer.
I load both big stick and Ball powder. I choose the more time consuming method of tossing a load from my powder measure then weighing it on my scale, trickling the last few grains of powder. Many of my handgun loads are scoop measured.
If this is a new combination and I have loaded test loads I have already installed my dies, which by the way, require the same precise adjustments in a T-Press and as a single stage press. The time comes from installing dies, removing the die, and then returning to the press to produce the final lot to load the load that provides accuracy, function ability, along with falling into the desired velocity range as recorded with the Chrony.
I rotate the turret and the pre-adjusted resizing die clicks into position. A lube case is picked up and neck lubed. The case is then placed into the press and resized. The case is wipe, and gets a quick visual inspection. And is primed before placing in the loading block.
I then charge each case setting in the block, after completing the charging I shine a light into each case looking to see that charge depth is consistent.
I then rotate the head of the T-Press bringing the properly pre-adjusted bullet-seating die into place. The bullet is seated into the case. In the pass I have crimped the case if required. Taking advantage of the multi able die head I can add another die for crimping if desired. This is the only time I would rotate the head without first returning the case to the block. The T-Mag II rotates and indexes easier then the old Spar-T press. As you can see I use the T-PRESS more as a single stag press, and not completing all phases of the loading process once the casing is placed in the shell holder the first time.
To me “Production Loading” is loading more than 20-rounds at a time. I prefer to load fifty to one hundred plus rounds of the same caliber in a run. I have a lot of handgun brass and I might load five hundred at a time. Shortcuts are not taken, and I may use the T-Press more like a single stag press most of the time. Ammunition I load normally exceeds the accuracy of factory ammunition. In the last forty plus years I have taken numerous head of Blacktail, Mule deer, and antelope with ammunition loaded on the Spar-T, and have continued that success using the T-Mag II press.
A Ruger M77, 7MM Remington Magnum is a Junker with a variety of factory ammunition, but is a winner with ammunition loaded on the old Spar-T.
Having started loading over fifty years ago with a Lee hand press, and a barrowed RCBS single stage press. I am happy with the product off the Lyman Turret Press. I qualified with a 30-06 using ammunition loaded for accuracy off the Spar-T press. There is no more serious business, depending on reliability, and accuracy.
Admittedly if I were a 1000-yard bench rest competitor I would have far pricier equipment. High price equipment does not replace quality control.
