I recently acquired a CZ 527 (7.62x39) and got a chance to fire form some brass. Using a Hornady head space insert I measured fired Winchester brass and got a spread of 1.215" to 1.217".
Measured some Lapua brass that I had reloaded and fired, the spread what much less 1.2175 to 1.218...
This is for a Bulgarian AK47, I reload for this rifle, but I'm running into problems when seating the bullets. On some cartridges (50%) when the bullets seats I can literally spin it- there is no neck tension. Even if I run it through the Redding taper crimp die (Not the Roll crimp) the...
Would it be a fair statement that a powder charge that produces the most consistent speeds (low SD between shots) would be the most accurate, assuming the same projectile, projectile seating depth and brass is used?
Ive been toying about getting a chronograph to help with reloading. I use...
243win- interesting. The speed I quoted (1732 fps) is from my chrono trials during autumn.
I thought the burn rate between 5744 and 1680 is practically the same.
For example, the laupa brass HS measured 1.219" pre-fired.
24 grains of AA1680 and a 123 gr. FMJ projectile gave me an extreme of 1.227 on the high end, down to 1.213".
A couple of months ago all I had was AA 5744 powder so I worked up a powder puff load of 18.5 grains with a 123...
I have that model, but the problem is that rim on the 7.62x39 greats chewed up by the extracting mechanism, so while that would not affect the function of the cartridge in the AK, the resized cartridge won't fully insert into the case gauge because it gets hung up on the "rim" of the brass.
I am reloading 7.62x39 for an Arsenal AK47. I know thats blasphemy - but hey I reload for all my firearm calibers.
In the past to determine my headspacing measurement (so I can set up my resizing die and later the Giraurd trimmer) i'll take fire-formed brass from my rifle and using the...
Im looking for an insert that will measure the 7.62x39 russian (AK47) and one for the 300blk. Not sure which ones

resized without the expander - tried to seat the .310 again and the bullet did seat. There is a bulge in the brass neck where the bullet begins.
But doesn't this just confirm that the resizing button is too large for the Hornady .310"?
So I had some Sierra .311" pro-hunter bullet- tired...
Thanks for the suggestions. After a little reading the original bullet was .312, so instead of trying to make a Hornady .310" bullet fit, I think I will buy .311 Sierra bullet instead and solve this problem. Of course in this frenzied climate, I'll be be waiting until winter for the Sierra...
Im reloading for my AK47 (7.62x39 ) using a hornady .310" fmj bullet. Resizing and reloading some winchester and some Remington cases that I shot gave me a several that the bullet was loosing in the neck. So I pulled them out and reset the Redding die (tightened it down). the resizing die now...
I am going to start reloading for the 7.62x39, so I'm building up my supply of brass by shooting Winchester and Remington ammo that I buy at walmart. I started measuring the headspace (Hornady Headspace comparator)
on my used brass that I shot from my rifle. Heres the problem - not only do...
Im looking at adding the redding competition seater die - does the Redding model measure and press off of the o-give of the bullet ?
I have a Hornady seating die while it does have a movable sleeve, i've noticed that it came with a seating adaptor (round nose vs flat nose) so I'm thinking...
Just wondering if anyone had any experience with this rifle: is the muzzle brake effective? How badly does it rattle your sinuses?
Whats the overall impression of recoil feel compared to an AR15?
I recently purchased a "higher end" bulgarian SLR101 AK47 and I would like to start gathering reloading components for. One of the first things I will need to get is brass, I'll probably buy loaded boxer primed brass and save the empties.
Since reloading for this caliber is not common...
Im trying to find a general consensus - my LE wilson case gauge dictates 1.355", but just reading posts on the 300 aac, the trim lengths are usually longer 1.365" range.
