New Powder Trickler Works Well

Recommended Posts

My new powder trickler works well and is a bit quicker than the Omega and RCBC 10-10 I was using before.

 

Very accurate with 1.530g (23.6 Grains) set it stops to within +/- 0.001g which is one kernel of powder.

Can trickle up from 0.000 to final set weight or just the last few mg from a just under target weight thrown charge. Anything within +/- 0.001 is more than acceptable as its one kernel of powder.

John,

 

Think that can rule variations related to power out of the equation ? :)

 

nice setup utilising the scale's capability, i assume it is an 'add on' i.e. If you already posses the scales to can adapt to fit?

The trickler comes from Canada and is compatible with a couple of lab grade scales such as A&D Fx/Fz 120i, Sartorius GD503 and a few others.

Neil,yes .Read John's post *2 and look at the videos.Impressive.

 

Of course,to get third decimal single kernel precision,you really need standardised kernels.This proceedure was detailed by G Salazar-one of the very top US Bench Rest shooters-and a superb writer on precision shooting issues-available on Accurate Shooter,maybe 2 or 3 years ago..in early April,I recall.

Well,probably not,Neil.

I've read,but not entirely believed statistically, Adam Macdonald's rather persuasive case for .02 being good enough....."Automatic Powder Trickler" (needs lab grade Sartorius scale,of course).

 

Steve- maybe 'perfection' isn't really needed...1 Kernel(varget) is about 1fps, or .035 moa at 1000y ( and that does assume absolute perfection in all other variables).

 

Salazar and Macdonald make for a good thoughtful read,on a quiet Sunday.

 

John,much appreciated info...I am most certainly not critical of accuracy,as a hobby;maybe a tad pragmatic -at least for some other shooters!

It gets my vote from its no messing after loading, ive recently been looking at the lyman gen 6 but when you watch video on what you have to do the clear powder isnt worth it,if you only used one powder then it would be fine, it needs a far better system before I would buy one.i really like the electronic type scales but most serious shooters seem to doubt them as they can waver.as mentioned on another thread everything has tolerances.i used the rcbs starter scales since I started reloading approx 15 years ago, not sure what model they are, I recently chronied some loads that varied 4fps, I pinch and roll fingers letting kernels go, trickling isnt in my reloading system, I have got one but its an ornament.you have got to learn to trust these electronic gadgets, I will get one sooner or later as I am beyond bored of the beam scale.

John,

 

Seriously impressive set up!

 

Please update us with empirical range performance when you get a chance.

George,

Couldn't agree more, my set up allows the same accuracy, but the automated speed of this is impressive.

It does look a really good and accurate set up but its the price of the Sartorious 503GD scales which is the killer and makes me wonder if the price makes it better than my tuned scales and target master? (for my use anyway)

Either way its a nice bit of kit John.

I use a targetmaster powder trickler with a tuned hornady beam scale for all my reloads and have done for years. Its made in the UK and it just works.

I use lab scales at work I find they drift and need constant re zeroing to be accurate.

The A&D Fz120i is a magnetic force restoration scale with internal calibration, it does not drift. Strain gauge electronic scales do drift and do require constant re-zeroing.

Tested a batch of ammunition loaded with the A&D Fz120i and Autotickler today. 55 shots fired, first 5 shots were bore fouling shots followed by 50 shots fired over a Magnetospeed chronograph at a rate of 1 shot per minute. Brass was once fired GGG, annealed, F/L sized in a Whidden Die with .221 expander. Primers were Murom KVB 223 and powder was 23.6 Grains (1.530 g) of TR140. I was after a single digit S-D and the best I've ever had before was 6 but usually low teens. I'm happy with the results.

My auotmatic trickler and scales arrived last week, unfortunatly the scales have got a fault on them when they are turned on so I'm just waiting for the replacement to arrive!

Bugger, hope the replacement arrives soon.

Bugger, hope the replacement arrives soon.

Should have been with the TNT driver today when he picked the faulty ones up but it didn't happen! They've assured me it will be here tomorrow.

 

The trickler is a very very well made piece of kit, hope it works as well as it looks.

Not sure why but it managed to sneek through customs without getting noticed which always makes me feel better :)
