Anyone have any experience with either of these running light supers? Seem a bit more suited for supers than the Blackout.

Not sure why you'd bother with this cartridge if you weren't using it in an AR15.
The appeal to 300blk is the ability to use both subs and supers, if you aren't going to use subs then there are bunch of other cartridges with better performance that work in a mini action rifle.
Unless you specifically want to use a mini action rifle with 30cal bullets I'd personally look elsewhere.
Because of another rifles action limitations (TC Contender). Which has pressure limitations but not length limitations like an AR. In a 16.5inch barrel and the fact there now a huge range if 30 calibre bullets that are made for 300blk speeds the 30 cal out preforms most other options due to the lower velocity window in which it preforms the 6MM ARC is the next bet but it still needs around 400fps more velocity on average for the projectile to function at impact.
30/30 comes to mind immediately.... could be a much simpler option to achieve same thing.
In your situation then it probably is a fairly good choice, certainly will have more oomph that a 300blk with supers.Quote:

I guess I'd go through the same thought process of choosing a cartridge, especially consider what factory ammo may or may not be available and what powder is available. I haven't looked much recently but the slower pistol type powders you'd use in 300blk/hamr don't seem to be coming into the country very often (not that its easy to find any powder at the moment).
I have been chewing on the idea of a switch barrel rifle based on a Howa Mini Action with a 223 bolt face and I think the 300 HAM'R/30 Apache/30-223 is a good option for a .30 cal in this platform. From what I have read you can duplicate 30-30 performance from reasonably short barrels.
I was trying to figure out what the most economical cartridge possible would be for deer sized game and below and I think the 300 HAM'R is pretty close.
-Easily available brass
-Small rifle primers
-Pretty much the smallest caliber to effectively use cast bullets, or a good selection of cheap factory projectiles.
-Small high pressure case so you can use smaller amounts of faster powder for the same velocity.
A cast 160gr HP going 2000-2200fps would be a sweet load.
This cartridge does nothing new, but it's still interesting.
Nope not even close.Quote:

I have a 30-30 barrel and trying CFE BLK now but it struggles to fill the case so expecting erratic velocities.
Same issue as above but more extreme. Lower pressures means incomplete burn of powder issue and burnt out suppressors. If you kept a long barrel and had a brake or bare it would likely be a great option but at that stage I'd consider 6.5JDJ etc.Quote:

I've got a 30-221 (300 BLK) Contender barrelset that Ive been pondering on what to do with for ages.
30-30 has been to the front of my thinking, mainly for practical reasons. Rimless cartridges in the Contender are a pain even though it does extract just fine, and the smaller case the worse it is.
My "main" contender barrel is the 6.8 SPC, 120gn at 2475 - it just plain works to 300M after that its out of snot. Its is fiddly to though.
I think if I was in your situation I'd just persevere with the 30-30, the erractic velocities you mention wont make any practical difference within 300M, and if you looked at some of the older IMR powders, I'm sure you'd fine a better match than the likes of CFEBLK. Cheers
You are so old school in your thinking, every time :DQuote:

It's probably just me but I don't see the appeal in a 30cal with such little case capacity.
My thought process is this:
the small case capacity means you either need to go for a very light bullet or put up with lower velocity with a heavier bullet, both result is a cartridge that will have a practical range of 300ish meters, if you are then limiting yourself to 300m then you may as well go go for something like the 6x45.
6x45 will have less muzzle energy but will have a higher BC bullet and higher muzzle velocity that at 300m you'll have performance similar to a 243 at 400-500m which most people would be happy with.
You then get the advantage of less drop and less effected by the wind.
Unless you need a lot of close range energy (like the Americans want for big game or shooting mass pigs with ARs) then I don't see the appeal in the 30/338/45/etc calibre cartridges unless the idea is also do run subsonics. I also think in the current climate where the likes of ADI have stopped producing the less common/popular powders I wouldn't want to get into a cartridge that needs a oddball powder unless I already had a decent supply.
In saying all that in the OPs situation, especially if he already has 30cal bullets and suitable powders, then 30 apache (30-223) would be a good choice as forming of brass is easy and 223 brass is readily available. If the hunting distances are such that 300blk/30-30 would be more than adequate the 30hamr/30-223 are giving you better perforamance with the only downside being burning more powder, which is likely inconsiquential in this siutation.
The appeal of cast bullets to me is guaranteed availability as long as you can find lead. Current projectile situation is exactly why I like the idea of casting. I also enjoy tinkering and I design my own bullets and machine my own molds.Quote:

The fact that you also have a speed limit of around 2200fps adds to the need for weight. 140-160gr seems to perform well at this velocity and it so happens that you can achieve this out of a little case like a 300 HAM'R, thumbs up all round in my books.
Subs are interesting and I have a short 45-70 single shot that I am loading cast 450gr flat nose projectiles at 1050fps which is great fun, but the trajectory and sights limit it to inside 100m realistically.
I have enough high velocity high BC laser beams that can kill to 800m+, cast bullets are the other end of the spectrum and is its own challenge, which I enjoy.
I would have thought you would be using 150 plus grains of projectile...the dirty 30 isnt a heck of a lot faster to begin with...the 4 loads I posed from ADI were 1500-1700fps with 150grn castQuote:

there are plenty of powders that will fill the case easily.... and some really cheap,really dirty stuff that likes cast projectiles too....it could even be said the 30/30 was MADE for it LOL....
Fair enough.Quote:
