Changing FMJ bullet for V-Max


Recommended Posts

I've just bought 100 55gr V-Max bullets for use in my .223 but haven't ordered the powder yet. Whilst I'm waiting, I do have some boxes of Sako FMJ ammunition that was pretty cheap. Thinking about pulling the bullets on 20, weighing the combined powder and splitting it evenly between the cases (might take off a grain or two) and shoving a V-Max back in. Would I need to resize the cases as they haven't been fired?

I wouldn't, I'm not going to say it will exceed safe pressure because I don't know, do you ??? What powder is it ???

You probably won't need to resize if you decided to. Just go out and practice on some target's at various ranges, 200-300 & 350 yards and see what you're groups are like.

I know a guy that has used military 7.62 by just pulling the bullet and replacing it with a 150 soft nose bullet and did very well too, we are talking Deer not targets.

I expected there to be a big difference because of the difference (not a great deal) in bullet weights but it seems that as the original bullet was held in with shellac and being slightly lighter than the replaced bullet, they worked out OK.

I should imagine it would work out fine using commercial ammo as long as the bullet weights were identical.

Every few years I ditch my reloaded brass buy 100 Federal American Eagle FMJ pull the bullets with a collet puller in the press ,replace with V Max still 55 grain .These shoot about 1 inch higher than my standard reload I then have 100 fire formed brass ready to start reloading .I have even sold the FMJ heads to make the V Max cheaper . I have 100 FMJ heads now if any one wants them £10

Further to this post, looking here (more for my benefit really)

 

http://www.sako.fi/pdf/datatables/SakoCartridgesDatatable2010.pdf

 

it appears my Sako FMJ (Speedhead) which are 50gr use 21.6gr of Viht N120 powder. This should give me 432gr total from a box of 20.

 

Now, according to this:

 

http://www.lapua.com/upload/downloads/brochures/2011/vihtavuorireloadingguideed9eng.pdf

 

a 55gr .223 bullet needs between 18.7gr and 20.7gr of N120 (maximum total of 414gr, leaving me 18gr spare - at £75 a kilo that's nearly 20p worth :D)

 

If the bullets come out OK that's got to be worth a punt...

I did a thousand Radway Green 223 ammo for a keeper years ago, he is on his last few 20yrs later. Binned the fmj and just shoved a 55grn Btip on the same charge, I dread to think how many fox's have copped it from that ammo!

 

If you want to be safe just go a bit lighter on the bullet.....

The thing is - never just guess in the loading room! I don't use any powder from my own pulled loads 99.9% of the time I am sure you will be fine doing as you suggest but still.

Necks will generally reseat on the slack side but this depends on the brass metallurgy, might not be good for field use away from practice

Going on the prices of my local rfd, Reloading my own ammo would still be way cheaper than using the cheapest Prvi .223 55g fmj rounds......

Quite so, but I've got some FMJ ammo and some VMAX bullets. Seems a shame to fire the FMJ purely to reload it with new powder/primer etc.
