Harrell Measures

[Buckeye_68]

Just out of curiosity, what powders?

H4198 , 2200 , N120 , CFE Blk ???

H4198 , 2200 , N120 , CFE Blk ???

My point is that with small charges variations in charge weight become more important. The same variance for a .308, would be a much higher percentage of the total charge for a .221 FB. Almost anyone can get good results with ball powders, for extruded powders, it depends on the shape and size of the grains. I am not sure that you will be able to throw H4190 or N120 to tight enough tolerances for cases of the size you mentioned.

Boyd,
You ever used a Belding and Mull powder dispenser?….. I have two of them and you can throw extruded powders fairly accurately with it but there really old school

Boyd,
Not to highjack the thread but you might find this cool like I do. In late 2020 I bought a B&M dispenser from a forum member for I think $150 I use to own one and loaned it out and it never returned. Anyway johara1 sent me a pm and said that was too much to pay and if he knew I wanted one he would have sold it cheap, we chatted back and forth and he told me he was at the end of his game, made me sad because like you and others on here he helped me a lot through the years. I told him I would love to have his as well but wanted him to sign it for me….. he did…. Silver marker
James O’Hara I will never get rid of it and it works beautifully,

A lot of water has gone under the bridge since I last played with a Belding and Mull. This morning I started a thread about throwing Varget that you may find interesting. How close can you throw with the B&M?

If I’m just shooting steel, a dumped charge works fine from the Harrells. I do use the 223 for some precision games, so’ll dump it on my A&D and trickle it up with a Dandy. I’m aiming for 21.5 grs and dumped it’s often just off a tenth or two. I’m sure it wouldn’t make a difference, but it’s one less excuse I have for an out of group shot.
Tried to dump a much coarser powder than LT-32, results were much more varied. Fine grain or ball powders dump the best.

I have a Dandy on the way , I will throw just shy and trickle up if need be . I loaded fire form rounds with my buddies Harrell and they shoot well . They have been hard on the ground hogs .
I’d like to find a powder that gives me good velocity and groups that will throw consistently with the Harrell without much fussing around.

What caliber and bullet?

Thinking of buying a Harrell measure for speeding up my process a bit ,I will primarily be loading 20 Vartarg and 17 Hornet and I’m torn between their pistol measure and their custom 90 . I’m thinking I should probably buy the custom 90 but was wondering if the pistol measure would throw these smaller charges more accurately?
Anyone have any experience with these ?

I have both of them you can't go wrong with either pick your favorite one and welcome to the Harrells family.

What caliber and bullet?

20Vartarg 32gr vmax, Sierra 32

 

[BoydAllen]

20Vartarg 32gr vmax, Sierra 32

Understand, I do not load this caliber, but having said that if I did, and wanted to throw charges into cases, I think that the burn rate of Accurate 2200 looks promising. I have shot a lot of ball powder in varmint loads. I have always checked loads in the temperature that they were going to be shot in, so temperature sensitivity was never an issue. Another powder that I would consider is LT30, not ball but very small extruded.

Boyd,
Well I got in bed a few minutes before 10:00 this evening and saw your new thread,… quite interesting I might add. I couldn’t stand it I got up and headed to the shop, had to dig through a couple totes before I found it!… I know exactly where the one I got from johara1 but don’t want to use that one even though it’s in better shape. I did not do as well as you with your SAECO’s but I was tired and didn’t sit down and really get into it but could throw within about 3 tenths measured on a cheap little Lyman scale the last bit I dropped which should have been the best so no excuses was over 4 tenths on my GD503. When I’m fresh I’ll try again tomorrow oh and it was with Varget.

Hi Wayne,
Take another look at the end of the thread, where I elaborate a bit on the technique that I showed with the video. The thing that you also need to pay attention to in the video is the sound of contact with the stop, and the speed and cadence of the operation. I have done an unreal amount of testing of different powder measures and throwing techniques, and undoubtedly this has made my operation of measures more informed as far as interpenetrating what I hear and feel. Realizing this, and that few are going to spend much time with powder measure and scale that reads to two places, learning how to become more consistent, my recommendation to new benchrest shooters is to get a chargmaster and battery pack. One more thing on the operation of drum measures....they generally have some end to end movement of the drum, and if the drum moves end for end during throwing, consistency will suffer. Yes I have tested this. The cure is to slightly pull outward on the handle during operation. There are a lot of little details that go into getting the most out of a measure.

Yes sir, I can do quite well with my culiver measures thanks to you many years ago. We had many a phone calls on little project!… those were fun times. As you know I have my own range with my loading room on the range so I don’t do much on other ranges however if I do I have my range boxes setup in them for powder is a Harrells Br thrower and a Parker tuned scale and a dandy trickler, if windy in another box a chargemaster I made a wind screen for. I can throw more accurately with the B&M I just haven’t used it in ages and no plans too except for fun little projects like this or if shtf scenarios. I think just for fun I’ll look into purchasing a thrower like your using in the video. Thanks buddy I’ll stay tuned in.
