progressive ok for long range precision??

Re: progressive ok for long range precision??

I use my Dillon for my 200-300 across the course ammo for my .223's. I take the time to load my 600-1000 loads on my single stage weighing each charge. I look at is as it's tough enough at those ranges and the last thing I need to be doing is doubting a flier to a "hot" or off load. I don't need to be chasing the spotter.

The littel extra time is worth the confidence in the ammo.

Saying that I have loaded some Very accurate ammo on that Dillon. I would say try it and if it works for you great.
 
Re: progressive ok for long range precision??

If brass is prepped like it is supposed to be done and is consistant then...

Load 10 of them and measure the over all lengths of a loaded round, preferably from the ogive. Should be within .001-.002"

Dump 10 charges and measure for consistancy.

I focus on having a consistant charge weight from round to round. That means the most to me.
 
Re: progressive ok for long range precision??

I have an LnL AP and I use it for match grade ammo when I am loading something with a ball powder. That's primary condition after all of the testing that I've done with it to see how consistently it seats, charges, primes, etc.

I use a competition micrometer seater with an ogive seating stem. When using thrown charges of stick powders like IMR4350 or IMR4064 I get +/0.2gr (0.4gr total variance) consistency in the charge. With BLC-2 and H335 I get significantly better, inside of 0.1gr total variance. This is great for 223, 204 Ruger, 6mm-223, 30-06, 308.

Total runout on the ammo is under 0.0025" across the 20 rounds that I checked on 30-06 ammo and 0.0015" on 223's. I'm accepting of that and for practice ammo and higher volume match ammo (re 223) I just load it on the LnL AP.

If you run it full progressive, yes, you will notice a difference. The powder charge would be the first thing you need to make sure is consistant, then the seating depth. If you wanted to size and prime all the cases with the progressive, then weigh the powder and seat a bullet single stage, this could give you accurate ammo.
 
Re: progressive ok for long range precision??

I have used both. However my Dillion is sitting in storage and will probably stay there indefinitely. I spent a month working with the progressive and I was never able to get things setup to the point were I was happy with it. For precision ammunition I'll stick with single stage.

My biggest complaint was that I could never get the powder dispenser to throw a consistent charge. And charge weight sits on top of my important list. If I can't get a consistent charge then accuracy will suffer and it isn't very safe either. Thus the press is now boxed up and collecting dust.

In terms of seating bullets and sizing brass the progressive presses are fine. It just takes a little more work to get all the dies setup. And with the advent of the removable die plates your dies only have to be setup once. Which is a great thing. It was a major short coming with my Dillion 450.

Given the choice I'll stick with a single stage press. But there are plenty of people who successfully incorporate a progressive press into there precision loading regiment. I just was tired to constantly having to mess with the powder dispensing system on my press.

I've done this as well, it works very well and makes it easy to keep primed brass ready for loading at all times.
 
Re: progressive ok for long range precision??

I have a 550 and a Co-ax. I have never tried to use the 550 for precision long range rounds. My reasons: My loads are close enough to max that I might blow primers if the 550 dumps a full grain too much(doubt it would happen, but I'm not going to find out). I top off each throw by trickling to the granule to make sure my loads are not a limiting factor and I still average 10-20 fps deviation. I want to know that when I pull the trigger that its either my form or the wind that affected the flight and not a reloading mistake. I have shot with guys that throw their charges without weighing, but I'm using varget and thats not an option.
 
Re: progressive ok for long range precision??

I use a 550 semi progressive for precision stuff and 3/4 progressive for short range(under 300yds)rifle.

I brush the necks lube and size then complete the brass prep.I always start with the brass ready to go.

Precision
Station one = prime case then rotate
Station two = throws charge slightly lite, remove case dump in scale pan then trickle to weight then dump back into case.
Station three = seat bullet
Station four = Not used for rifle
Definatly not full progressive but once you get it down it moves along pretty good.
 
Re: progressive ok for long range precision??

Bart Bobbitt has posted about the progressive that loaded for a US team and how great the accuracy was.

I will never achieve that accuracy.

Still, the progressive here gathers dust, as I prefer the single stage.
 
Re: progressive ok for long range precision??

Dillon 550's was used to load all the Palma Ammo. Lots of good scores shot with that ammo! They are all the same for every team! The only way to group it is weighing your rounds!

So, Yes! The Dillon 550 can load match quality ammo.

Hi Chaser,

I'm new to reloading, just started last week, so YMMV with anything I have to say. However, I do have an LNL press, probably the same as yours, so here are a couple of thoughts:

1. You can forget using extruded powders in the LNL powder measure - at least in mine, the loads vary quite a bit using the fine-grained extruded powders and you can completely forget about using longer ones like IMR 4064, which just jam up in the drop tube.

2. Flake powders like H335 seem to meter pretty well, but you are not going to get the same degree of accuracy that you would if you meter by hand.

Taking that into consideration, what I've been doing is using the LNL for deprime/resize/prime, then I weight each charge individually, then put the round back in the press to seat the bullet. I do that because I've found Benchmark (extruded powder) works great for my rifle, but otherwise do the full cycle when loading with flake/ball powder like H335.

I think that the reality is that assembling high-precision ammunition is a very labor/detail-intensive process and you may want to use the LNL as a fancy single-stage press or just get a nice single-stage unit like the Forster co-ax if you can afford one - I'm kicking myself for not having researched presses more when I bought the LNL, because now I'm getting more into precision shooting and I think I would have gotten better mileage out of a Forster single-stage than the LNL.

Anyway, for what it's worth I hope this helps.

Cheers,

Russ

David Tubb uses a 650 Dillon with a Promesthuis (spelling)
powder dispenser. You can get a floating die holder for the 550 and
650 which apparently aids in die alignment.
 
Re: progressive ok for long range precision??

thanks guys, i got the LnL for pistol matches where bulk ammo rules supreme, so i guess in short i can use this for now and weight charges myself, and will prolly get a single stage also because not toys is never a bad thing
