I always put down a lint free white cloth (cotton or use a few sheets of kitchen towel) which at least covers the area beneath the scale and at all points where I am transferring the powder to the case.

Any spilt powder can go straight back into the next charge, or I can put it back in the tub at the end.

Like the OP I also use a digital scale.

I normally drop the powder from a lee perfect powder measure to within half a grain (if I'm lucky), or scoop it from a container of some sort, then make up the difference with tweezers (and yes it is to within two kernels but my OCD won't let me do it any other way, and I enjoy working that way).

I also weigh all my bullets and sort my neck turned, neck sized clean and shiny cases, but only when doing load development.

Once I have my load I just grab a bunch cases and bullets make the rounds up and get out and shoot, then blame any poor groupings on my detached retina, the blinding sunlight, unreadable wind, trigger slapping, the wife etc, etc.

Your welcome.

Thanks for buying it.

Thanks for looking

Having recently pillar bedded my Remmy 700 .223 in a laminate stock the AICS chassis I had it in for many years is no longer required and may be of use to someone.

I bought this stock to add weight to a factory remmy 700 sporter, but a recent rebarrel added over 1kg to the weight of the barrelled action and it no longer needs the additional weight of the stock.

From memory this is the AICS 1.5 stock, used on a short action Remmy 700 in .223.

It comes with a genuine steel AI ten round magazine and a polymer MDTTAC ten round mag. Both work prefectly well, but I only ever used these with five rounds at a time as the original magazines wore around the guides and eventually wouldn't keep the rounds in place.

The stock has been well used, and cosmetically shows the signs around the sling points and bi pod area, but I had confirmation from sporting services uk that all replacement parts are still available should the buyer feel the need to replace them.

The price is £250 collected, or I can post it for the cost of shipping (quotation from the courriers is £10 based on it weighs close to 4kg including the magazines and packaging).

#SOLD to Remmy308.#

Price now dropped to £500.

This scope has had very little use and is like new.

The Remmy action will normally look like it's cratering the primers (mine does even on light loads).

Also soft primers have a tendency to appear to flow (I found Winchester always flatten but not flow).

Vhit site shows the upper end as being above 27 Grn, so you still have enough space to allow for temperature variation.

Any signs heavy bolt lift?

I found the same thing with the new barrel on my .223, and after seating them back 10 thou the FPS was up, but no pressure signs.

I have around 300 many times fired PPU, and recently decided to neck turn them all (lockdown boredom). It made a significant difference to the group size, so probably worth saving a few of the factory cases you already have, even if it's only to try case prep ideas out.

I used fired cases to learn how to develop loads and, as above, bought decent new cases for target work but still used/use the old stuff for field work. Nothing worse than spending a few hours on prep work on new cases only to watch them sail off into the long grass.

thanks chaps so i can push the load up a bit on the 25grain hollow point i will try 11.2 and 11.4 see how they group this lovex do63 suppose to be the same burn rate as vitn120 any body tried that powder .

DO63 is double based, so N120 will perform very differently.

My Hornet never liked either of the Hornady VMax offerings, I never tried the hollow points.

Try the 20grn varmagedon with either DO63 or N120. Varms are also cheaper than Hornady if you buy the 250 box.
When the cartridge was first introduced Hornady published the recommended min/max for N120, which was;

N120            
20 Grn V Max    9.7/3200-10.8/3600 grns        
25 Grn V Max    9.3/2900-10.0/3100 grns        

For a better quality bullet try the Berger offerings.

Hi Guys seen this on another forum and its free all you have to do is a quick register looks not bad but think it will take a bit of getting used to , I am just a beginner so a bit over the top for me but easy to instal etc but thought some of you guys could make use of it , and if you have Quickload you can import from its data base 

https://thereloadersnetwork.com/2019/12/13/gordons-reloading-tool-grt-how-to-start-using/

How are you getting on with it?

Works ok as free software, works better when you become a patron and unlock the additional features.

I'm still playing with it but, as a long time QL user, it is taking time to find the features I used most on QL.

What bullets are you using?

My lee press is very old and worn, and the handle falls off, but the bullets (even PPU SP) all seat to the same depth when measured to the ogive using a comparator.

Kaboom I am careful with powder , just spill a bit on the floor the wife's hover didn't like it.

After the second time I tried filling the charge master with the drain plug still open 😳, I always make it a point to spread a clean, lint free, white cloth out before working with powders.

Even if I don't want to reuse the powder it collects, it saves it getting sucked into the vacume cleaner.

I'll take these if you still have them.

Hi Cooter,

It's the heat of explosion (energy content) of N32C Tin Star that is very slightly lower than Trail Boss. So 3,040 kJ/kg for N32C and 3,070 kJ/kg for Trail Boss.

The volumetric density of N32C is higher (it weighs more per unit volume) than Trail Boss. The volumetric density of N32C is 0.459 g/cm³ and 0.310 cm³ for Trail Boss.

So you can roughly load weight-for-weight, but not volume-for-volume.

For example, a 308 case loaded to COAL of 2.800" with the aforementioned Hornady 220 gr RN and a full case of Trail Boss (14.49 gr), according to QuickLOAD's estimation, gives a pressure of 34,511 PSI and an MV of 1,319 ft/s from a 20" barrel.

If you load volume-for-volume, the same case filled with N32C weighs 21.45 gr and gives a pressure of 62,514 PSI and an MV of 1,627 ft/s. That pressure of over the maximum average pressure allowed for the cartridge, so very high!

If you load weight-for-weight, 14.49 gr of N32C gives a pressure of 35,639 PSI and an MV of 1,319 ft/s. So identical velocity, and only slightly higher pressure.

The pressure is different as the two grain types and hence their burning characteristics are very different, with N32C being a hollow tube and Trail Boss a thin washer. There are obviously lots of other minor differences, such as coating, deterrents, etc., etc., but their morphology is the primary one.

So, as long as you load weight-for-weight, and start off at the lowest recommended fill weight of a Trail Boss load, you should be fine most modern cartridges.

Neil

Neil,

It was your first point that I recalled, but thanks for expanding it. 👍

Just to add to your post.

Based on the above powder information it means that to use the same powder weight of N32C as could be used of Trail Boss the case will be only half full, and to get it down to sub sonic level (10 - 11 Grns) means it will be around the 50% fill level, which can mean an uneven burn, or using fillers.

Using Trail Boss and not N32C I worked a load up using the Hornady 220Grn RN bullets which was good enough for vermin shooting in the woods.

I recall reading that the powder volume density for N32C was slightly lower than Trail Boss, but there wasn't much in it.

Data on 223 and N120 is available free here:

https://www.vihtavuori.com/reloading-data/rifle-reloading/?cartridge=7

Personally I would have said N120 is a bit fast for the caliber but you should be able to get away with in on the 40 gr VMax,

For the 50s etc I would deffo look for something slower like N133.   

Ideally you want a pretty full case,  (95% or so),  that way you get a uniform velocity, so a closer shot to shot velocity and thus a smaller group with less vertical dispersion. 

I would also recommend a look at Sierra Blitzking,   I use the 20 caliber 39s in a 20BR and 1 in 9,    hell of a good bullet,  holds together at over 4000 unlike the 40gr VMax.   But best accuracy as is often the case is way below top speed,  in my case about 3600.

I also thought N120 was a bit fast but, when I sold my .17 Hornet, I had to find a use for a near full tub of the stuff so, after reading a few posts from others who recommend it for lighter bullets in teh .223, I tried it with my go to vermin bullet which is 52 Grn AMax or 52Grn SMK.

I ran it through QL to get an idea of max load and full powder burn then worked from 20 Grns up to 23 Grns.

I settled on 22.3 Grns (worked all the way up to 23 Grns with no pressure signs, but I prefer accuracy over speed, and I like to keep a margin for ambient temperature increase) set at the book col and it easily goes clover leaf at 100 yds.

The speed is 3200fps average and when zeroed at 200 Yds it is point and shoot on most vermin out to 250yds (1.5" high  at 120Yds).

It drops off pretty fast from 300 yds, but it is very effective for it's intended purpose.

I Just recently purchased a Tikka CTR 24" 8 twist .223 for this very task, unfortunately i can't use it, i haven't even thought about what to run through it, so if anybody has any ideas on a good place to start for a varminting load please enlighten me.

i have in stock already 

40 gr Vmax

50 gr Vmax

i am undecided what i should get in the 60 - 80 gr range any suggestions ?

Powder wise i have

N120

 

 

50Grn VMax with N120 should work really, really well. 40 Grn VMax are also good but they didn't like being pushed fast through my 9" twist remmy, so don't go for speed.

I used the 20grn in my .17 Hornet and they were far more consistent than the .20 or 25Grn VMax.

I ran them with DO63, and also tried them with N110 and N120. All gave excellent results.

Try Reloading Solutions, they were always very good.

I tried everything from N110 to N150 and found that N133 was the best powder across all loads for my 1..9 Twist .223. I used to get the best and most consistent performance from Benchmark and H322, but changed to Vhit powders for availability.

Just my experience with my rifle but,,,

40Grn bullets run well with N110 or N120 if it is all you can get.

50Grn will run with N130 and N133.

55Grn and over run well with N133 and reasonably well with N140

60Grn and above I run with N140 and have tried N150 which worked surprisingly well.

I recently used my last 52Grn V Max, which I ran with N133,  but have always used the 52Grn SMK with N133 as the benchmark.

If you really want to stay with N133 I have a full unopened tub which I could part with.

25mm Mounts are on hold pending collection.
