.223 rem reloading with hodgdon BLC-(2) and sierra 69g HPBT matchkings


Recommended Posts

I don't know about a 69gr bullet. But I use BLC2 in my 223 using 27gr of powder and a 55gr Blizking bullet. Perfect!

Thanks for that im target shooting with a 1:9 twist,so after a hevier bullet. According to my speer book it says magnum primers only the others dont say anything about pimers,could you shed any ligjt on the matter. I will be using cci bench rest primers.

Cheers Albert.

Any newbie reading this be aware lighter bullets generally can handle a higher charge of powder opposite to what many might think

I can not guide you on your 223 question.

 

What I can tell you is that I used lots and lots of BL-C2 in 222 for many years and many bullet weights and it is very forgiving. It does like to flash in low light. I have used it in 308 also.

 

The magnum primer requirement is due to it being spherical powder. Most spherical powders need a hot flame to get them going especially if no compression exists in the loaded round.

 

I did my 222 loads without a mag primer but all my loads were compressed!

 

Don't be put off from using it, it is a good choice.

Cheers and thanks for that,it was only the speer book said that magnum primers must be used,all other used standard for the tests. Im going to test them on The range on sat, weather permitting.

Thanks Albert.

that bullet prefers a 1 in 8 but you might be lucky sierra in my manual states blc2 start 25 and max 27.4 col 2.260 whilst hodgdon states start 24.5 giving 2833 40,600 cup max 26.5 giving 3029 50,100 cup(pressure) so it looks like your starting nice and low good luck check for key holing on your first batch make sure they are stable

good luck mike

Thanks mike That's the same info I found.

my .223 is a 1:9 varmint and info says 69g is the one to use. not shot with said bullet,but shot 69g ppu match factory before. Still not tested the homeloads due to range being shut due to weather.
