Hi!
I have a really nice load for my 25-5 with a 175 and 200 Gr LSWC and 6,6 Gr VV N310.
I use standard primers but I´m thinking of switching to magnum primers because of a lot of powderresidue. Does anyone of you have any thoughts on this?

Edmond
I reduced the powder residue by increasing the diameter of the bullet in my model 25s.
My 45 acp and 45 auto rim use .453 and my 45 Colts use .454. In both cases I fit the cyclinder not the barrel.

Edmund,
Welcome to the forum. Yes, I have thoughts of doing this very thing with HS-6. Now, I think that VV N310 is 15% faster than Bullseye. I would find it hard to believe that changing primers would help with the residue left with that fast of a powder. I'm not overly familiar with VV powders. Is this a tendency with all of them? I know that the Accurate powders, mostly AA#5, have the same problem. In an auto it is of little consequence, in a revolver it can stop your match! Let a few grains of that stuff get under the ejector star and your cylinder won't turn!
Now, like I said earlier, I'm not familiar with VV powders but if your load is towards the top of the data make sure before changing primers you reduce your load back to starting levels first. Work up your load from scratch again. Pressure can spike drastically with the faster powders when you change just one little thing.

Be careful, maybe you could call VV and speak with one of their technicians.

JP,
I am using a Phil Sharpe modified Elmer Keith bullet. The crimp COULDN'T be more unless I were to cut the bullet in two! The crimping groove is full to say the least.

Like these:

Edmund,

Welcome to the forum.

I was looking in the newest VV Manual in PDF and saw where they were using a LP primer with the loads they had listed. However, I also didn't noticed any loads with N310.

I'm curious about why you aren't using a local powder, like N2020 or the Bofors equivalents of Alcan 5 or Alcan 7?

Good morning, in my end of the world!

Thank you all for your answers.
The bullet I use have no crimpgroove so I use a Lee factory tapercrimp die.
My bullets are .452 and I will try to get hold of some .453 or .454.
I did a lot of reloading during the 90´s and back then I used Bullseye and 2400 but those are hard to get by here in Sweden today.
I have been in contact with VV but they do not have any reloadingdata for this cartridge/powder cobination.
This is a load that I have tryed out myself and it works fine in my gun.
I will try a rollcrimp to see if the powder will burn more completely.

Have a nice day//

Edmund,

The extra crimp may give you enough bullet pull to clean the burn up, but a heavier bullet may do as well too.

You should be able to tighten the Lee FCD some more and possibly do as well as a roll crimp. I think you'll lose a little accuracy with a roll crimp, but that may not be a factor in a hand gun.

I have shot 200 gr SWC with 4.1 gr of VV310 for years. I usually load VV310 like Bullseye. IMHO 6.6 gr of VV310 is pretty stout, particularly in a Model 25. I would back it down to 5 grains or so if it were me. What does your primers look like, are they flattened or cratered?

Edmond
Here's another trick to try.
Taking your case neck expander, polish down the shank that expands the case, not the part that flares the case mouth.
Between this and your crimp you will have a much tighter grip on the bullet causing more resistance.

Hi!

Thanks for all info.
I will give it a go tomorrow and try with a roll crimp.
The primers looks just fine, compared to factory ammo that usually are more flattened out.
I thought that 6,4 gr of VV310 was a little too light charge, hardly any recoil at all, I compared with Bullseye and backed of a bit.
Hopefully I get hold of a chronograph at the end of the week and can get some speed on my loads.
Tonight I will take one of my expander tool apart and give it a go.

Tank you all!
Best regards from Sweden
