Bullets shaping like hour glass???

I don't think that'll work ganderite, it's the Varget,it fills to much of the case.
And a combo of the long TMK and my magazine length.

I'm getting way to much compression at 2245.

Even at the suggested start load,from Sierra, they were distorting,from so much compression.

They would probably work well for a bolt gun,with a longer magazine COL. (Varget)

I'm going to move on to CFE,

In your case it may be too much, but it is an easy solution to a common problem. Fix your die and try a drop tube perhaps?

Lol, you got it didn't you.
You need to take some Valium dude

Well... he was trying to drug me... that doesn't bode well... "I'm going to the washroom, can you watch my drink for me?"

I don't think a drop tube would work ,as they are compressing so much.
I think I would need a COL of 2 decimal point 260 at the very least.

 

[Daver_II]

^^^^ you found the decimal point... ha ha

this thread has been a run read.... I will let you get back to it.

A drop tube will definitely help, I had a similar issue in the past, made my own from a piece of tubing and was surprised how well it worked for me with varget in a 223rem case

If somebody used a faster powder, you wouldn't have to go to all this trouble, Have tried compressed loads and drop tubes numerous times, found it was nothing but trouble with spilt powder etc. Just my thought's.

I was talking about this thread to my wife - she is a practical thinker and she thought that a mortar and pestle might be the answer. I nearly pi$$ed myself laughing...

Ok,so what would happen if you actually ground it up, using a min load of course

Grinding it up is NOT recommended. The gunpowder has coating on most of the manufactured grain to control and optimize burn rate. Grinding powder up doesn't remove the coating but it creates a lot more surface area without coating, the finer the powder is ground. The resulting gunpowder burn rate can be altered. I personally would not do it. This whole thread comes back to my very first reply. Too much compression with the seating die insert crushing the bullet. You can modify the seating stem to reduce the effect by spreading out the force on the bullet over more surface area, but when the case is full and the powder cannot be compressed further something has to give.

Just to clarify,I'm not going to grind it up

I don't think modifying the die would work.

I could trim fired brass to max length and seat to my magazine max length, using a min load of Varget.
That might work.

But why bother, I found a good load ,with CFE.

 

[Ganderite]

Grinding up powder would increase the burn rate. Not a good idea.

Hey,
I just loaded some 69 g Sierra TMK, Varget powdered.
.223
Only COL,I could find was on hodgdons site.
Which was for a Sierra 69 g HPBT.

There was a lot of compression.

Anyway,all my bullets have hour glass shape? Or kind of a indented ring,around the upper part of the bullet.

What up with that?

I did use a small amount of crimp

AND A FOLLOWUP OF:

The max load almost fills the case.
I got the data from Sierra,via email.

But they didn't give COL. ,that's why I used hodgdons site,which said 2235 COL.

Maybe I should increase the COL?

It's normal ,for Varget to be compressed.

Wow....

Just...

So much NOT to try in this thread.

So that must mean that there was an immense amount of information about what to do as well.

First off, buy a couple of reloading manuals, READ them and most importantly UNDERSTAND them. This whole thread is about someone reloading who still hasn't cared enough to perform due diligence and understand the PROCESS in detail so that they can apply them anticipate the RESULTS. You just don't take someones max load data (see quote above) and try to stuff a bullet on top. You don't grind up gunpowder to make it finer so that it packs better. If you do, make damn sure you are the only one at the range when you pull the trigger on it. I personally don't want to be anywhere close.

The things you can easily do like backing off load levels and/or changing the type of powder used should be obvious. Other things such as finding out where the ogive contacts the lands with the new bullet and measuring it takes a bit more effort but reaps rewards. Starting at minimum or close to it and working up loads watching carefully for indications of problems both as you are loading and when you are testing is an integral part as well. It is all covered in most any reloading manual and there are many available.

Take a look at Ganderite's taglines. Pretty much says it all, LOL.

I didn’t start at max load.

Started at min and still had the same problem.

No worries though, I wasn’t going to fire them , grind up powder,etc.

I got the answers I needed ,and a lot I didn’t

Anyway,I pulled them all and decided to use another powder.
