Either approach will give you lead exposure. Honesty, PPE is both the smartest and best way to help mitigate exposure. If you go dry…You can also drop the exposure levels by way of dust based particulates down on your media by treating it…this isn’t to the levels of smart use of PPE… For reducing dust the old school way started with transferring it from bucket to bucket outside on a windy day to get rid of the fine particulates as much as possible before even using the media. Then also treating it and running it prior to even using it to tumble or finish polish. Dryer sheets are somewhat a home fix (to some extent) but treating it helps with dust WAY more. Also helpful is rotating your media and varying your mesh size for the application. Many people use too fine of a media for the application and because it’s incorrect they end up tumbling longer, which also can produce more dust by breaking down the granular husk/shells with heavy tumble loads.

We use Unis primers commercially (SPP, LPP, SRP, and LRP) for our new ammo and have always had great experiences with them. They can be hotter than some other primers so adjust accordingly and test/verify. We buy them in batches of 250-350k at a time and the QC has been superb as has their lot to lot consistencies (they are an ISO company so it should be). This is verifiable by both our in house and the 3rd party testing/analysis company we use. A note on them is their cup diameter is on the large side and can be tight. They prime in new brass very well and are a great choice if your looking for rounds higher on the column. We frequently get single digit SD’s with them in our random pulled test batches using their SRP’s and SPP after we retool, tune, and confirm. Now I will say if loading anything CNC’d like the primer pockets on the NAS3 9mm, 380, or even their 300 AAC cases the primers are tight. These pockets are cnc’d to min tolerances and primers resting on the high side of the SAAMI tolerances are not as easily seated.

We commercially load using Mark 7 Revo for rifle as they are great machines when tuned properly and maintained. Indexing and dwell is slowed for larger things like 6.5/308 or even 300 AAC with heavy subbies. With heavy projectiles they are too heavy and can topple on the ejector arm if your speeds are too high and can bungle the feeder arm. Also if you rock a revo get the second and/or 3rd guide rod (especially if you want match level). If your ok with 1.2-1.5k / hr with match precision (again if set correct) and using high quality brass (Lap/Alpha/Peterson) and pow that meters well is absolutely comfortable. At/around the 1MM mark you WILL need a rebuild on the bushings and some other wear parts. If you want higher rates and are absolutely ok with some loss of concentricity and are chasing fast production look at an alpha/BRT, vasini, or Ammoload Mark.

This was something we had a problem with. We made sure the springs on the bottom side are lubed and we took the collator plate out and cleaned it. Those springs are replaceable. It ended up worked for us. Between the cleaning ensuring they plastic shuttle (outside black piece to keep primers from flipping) and the to lube it rerouted all the way around and we haven’t had problem sense. We have over 1/2 million cycles on ours.
