Sinclair priming tool unbox and primer tool performance test
Вставка
- Опубліковано 1 лис 2019
- In this video we compare the performance that we get with the Sinclair priming tool to our standard process and try to see how much our primer seating process affects statistics and group size. We unbox the Sinclair primer tool and show what comes with it.This test uses the Hornady 140 ELD-M, H4350 and CCI-41 primers to see if your primer seater makes a difference to how our load performs.

Hey the thing I love about your videos is your honesty. Your willingness to express the likes an dislikes an open minded to other opinions. So I have both I been playing with primer ignition. So the Sinclair would be good for the guy that maybe does not load much ammo. Mine is put away maybe a give away. Now my Frankford has to primer button you can roll an set your primers at any depths an you can run 100 primers as fast as you can squeeze the same handle. Plus come with all the shell holders an seated in a nice holding bo,x. I'm thinking about Gregs but 625 dollar's is alot an if you watch he really has to pull down hard alot for the same outcome. Just another opinion out of many again comes to personal preference. Great job on the videos.
Great priming tool. It is a much slower process, that in my opinion, provides me with greater control in seating my primers. I'm after accuracy, not quantity when I hand load. The Sinclair primer tool is just what I wanted. Very good video.
Glad you enjoyed it.
The Frankford paining tool is excellent and it feeds primers.
The Sinclair primers has the ability to set seating depth if you don't want to seat by feel. It's just not externally adjustable like the FA primer.
I use the Lee ram prime die on my press, has great "feel" and uses standard case holders, very cheap too.
A little bit about different brands and types of primers.
Which ones to use, when and why.
All CCI and Reminton primer, plus Winchester's small pistol are the safest to use in automatic priming tools.
Federal burns hotter and cleaner, yet are according to the Richard Lee manual "one tough dragon to control in the automatic priming systems".
Modern Reloading Second Edition Richard Lee Revised 2021, page 60:
To find out why some brand primers explode violently, I talked to an expert, Dave Anderson, now retired from CCI. He told me primers are charged with one of two types of charging compound. One is called "basic" and the other is "normal." The primers that use "basic compound" must not be used in Lee Priming tools because an accidental discharge is very violent. The "normal compound" is less violent and causes little damage to the tool. The user is easily protected by safety glasses.
Metallic Cartridge reloading, Robert S. L. Anderson, page 20:
In the firearms industry there are two types of lead styphnate primer compounds - "normal" and "basic." There are presently four manufacturers of primers in the U.S., and all of them except one uses the normal lead styphnate primer compound. Federal is the only manufacturer that presently uses basic . The common ingredient to all small arms primers is lead styphnate of which there are several different varieties. Basically it is in crystalline form and is very explosive. Normal lead styphnate is composed of large irregular crystals, which are slightly acidic when wet, somewhat more brisant at lower temperatures (good for military use), and they burn with a cool flame at ambient temperatures. However, it is somewhat harder to get an even mix of components in normal lead styphnate primers because of the larger irregular crystals and the fact that the "mix" often requires some metallic fuels (such as powdered aluminum) to help make a magnum primer. Basic lead styphnate is composed of small regular crystals and unlike the normal mix is not as acidic and will not attack primer cups when wet. Basic lead styphnate is easier to mix than normal variety and there is no need to add metallic fuels. The basic primer flame is very hot and will easily ignite most powders and therefore Federal does not offer a magnum pistol primer. However this style primer is slightly less brisant at very low temperatures (- 20degrees F. to - 40 degrees F.) which would make normal primer more suitable for military purposes.
Metallic Cartridge Reloading, All New Third Edition, M.L. McPherson, page 29:
Certain brands of primers might be unsafe to use in some priming tools like Lee's AutoPrime because of the potential for mass detonation. With these tools, should an operator detonate one primer, as can happen when a handloader tries to seat one primer on top of another, the detonation subjects other primers in the tray to shock and an incandescent flash. If this shock and flash can detonate a second primer, there is the potential that most or all (perhaps 100 or more) primers in the tray might detonate en masse. Such a simultaneous detonation would be a disaster. Lee has tested all available primers and, excepting CCI and Winchester, all brands produce an unacceptable number of mass explosions when the primer being seated is forced to detonate (by heating in a remote explosion-proof box). By comparing Federal and CCI primers, we can gain some understanding why brands very in this regard. Federal primers do not have a foil covering over the primer pellet; an application of a type of paint replaces the foil. That sealant is easily ignited and highly flammable, possessing a very low kindling temperature. These are beneficial characteristics; among other things, they help reduce combustion residues. However, use of this pellet sealant makes these primers very easy to ignite. Exposure of the open front of the cup to the flash from an adjacent primer easily does the job! Conversely, CCI primers have a paper foil almost completely covering the front of the pellet. This foil deters pellet ignition because it is only moderately combustible and has a relatively high kindling temperature. A short duration flash from a primer is unlikely to ignite the foil or penetrate through it to ignite the pellet underneath.
Glad I watched this. Cross this off my wish list for Christmas lol.
I am favoring the Frankford tool. I have used rcbs forever, but there is no good way to control seating depth of the primer. You control the pressure, yea, but I am not real confident about consistent pressure or depth. Specially if I am loading 50 or 100 rounds. Normally I just do small, discrete batches but every now and then ….
never test for groups with magnetospeed attached to the barrel, it will change the barrel harmonics, result in a better or worst representation of what your gun actually perform. My 0.75moa gun performed a 0.25moa group 10 shots group at 100 yards with the magnetospeed attached.
Brother what?
Have you used the 21st century priming tool, just wondering which one you would prefer
I have the Lee it has the tray and works just fine
Good video. I use an old RCBS small bench tool that hasn’t been made for decades and is wearing out, looking for something new and the FA keeps coming up in primer thread after primer thread.
Hi Sean, it's certainly a good tool and I really like being able to control the depth. I will mention though if you load a lot at one time or are sensitive to it, my hands get fatigued after a while.
The single feed has kept me from this primer as well. Thoughts on the primal rights?
So, now years later…. What are you using to prime with now?
Hey Bolt action, What type of shooting rest are you using? It looks like it has some kind of crazy mechanisms
Another great video. I also have a frankford arsenal hand primer, loading for 30-06, lapua brass and fed gold med large rifle primers. I have to have the adjustment wheel cranked up to max adjustment to get the primers to seat just below the case head. (.002 below the casehead) measuring with my caliber,and getting the handle to bottom out. The priming tool seems to be working perfectly, I just found it odd that it has to be set to max in order for the primers to be seated properly. I've had know experience with other priming tools as I'm just getting started in handloading.
I have watched benchrest shooters seat primers with a sinclair seater, throw a charge with a 10 year old powder measure and then shoot .1 5-shot groups. The most important factor in accuracy is barrels, bullets and bedding. The rest must be ironed out, but ultimate accuracy hinges on the above.
I was just at Brownells, $20 for a shell holder. I'll stick with my Lee set up.
Have you tried any bench priming units? I’m in the market for one and I’m between the Lee and the RCBS I think
Did you seat primers to same depths on each tool?
Thanks! God Bless.
Still using my RCBS hand primer for both SPs and LPs. Have had any problems with it as long as I hit full travel each time.
I use the primer on the top of the Forster Co-ax press. Do you think it is on par with the handheld priming tools?
Only if you don't want to "feel" the seating process.
Same, I always think that hard stop is the way to go. People don't like the Co-Ax priming system for some reason. I love it, even though it's slower than bench or hand priming.
Love my FA primer. I pull 10 primers and set the stop to bottom out on the shortest one, that way I know they are all on the bottom of the pocket and/or slightly compressed. If there is a better feeling, more consistent way to seat and still autofeed I don't know what it is. 21st Century and K&M also make really nice primers, but no autofeed. My one gripe about the FA is I wish the load and feed were on the sides instead of the front and back. To me, it always feels upside down in use.
I agree completely, but it seems to work pretty well
Not having a primer feed is just a deal breaker. I'm sure it's great quality, but it's really expensive for what it is and what it does not do. Locking in brass, gimmick.........
It’s a no go for me!!
I like to have one but $100 it to much for me
It certainly isn't cheap that's for sure.
