36gr vs 40gr CCI Mini-Mags, why?



Log in to see fewer ads
I inherited a fair amount of 22LR ammo from my late father's hoard. It includes 2.5 bricks of both 36gr and 40gr CCI Mini-Mag. I'm sure he just grabbed whatever was on hand. In the end it doesn't matter all that much to me since I'm primarily a plinker, but what is the intended purpose of 36gr? Seem like an unnecessary SKU for CCI to stock.

Competition for the Federal 36 grain cphp would be my guess.
Almost the same mv. Handy squirrel, rabbit and rodent round.

I think the 36 gr is hollow point & the 40 grain is solid soft point.

So, what makes the 36gr round "better" for small game than the 40gr?

This, the HP expands and kills quicker on a less than perfect shot.

Check the boxes and see if they are Omark with the big C head stamp or Blount with the small C head stamp or another company. It will help date the ammo. I really liked the older Big C head stamp CCI. When it was a smaller company I think it had a better product quality overall.

I'll look next time I get a chance. That said, I'd have to guess it is 4 to 6 years old. He has been gone for 2 years and the previous 2 years he couldn't really shoot but that wouldn't have stopped him from buying ammo.

70s through mid 90s CCI was really good. Nothing wrong with the current production except people seem to complain about the lack of consistency

Competition before 1997?

Blount Industries, during its previous ownership of CCI, purchased Federal Cartridge on November 04, 1997. Ever since then CCI and Federal have been under one companies proverbial wing.

Lack of consistency?

Yeah, that'd be an accurate description.
Some batches appear to have been assembled with a modicum of quality control.
Some batches come off the assembly line full of dents, dings, chips and poorly seated bullets.
Set that chronograph out front and it confirms that vertical spread is mv related.

CCI never claimed it was intended for benchrest competition.
So why should we complain, right?

Sure NIB, competition.
If the Federal version is selling well, offer a similar cartridge with a CCI label.
Seems to work for Hornady, Federal, Norma and Remington with the rimfire magnum cartridges.
Wait, those are manufactured by CCI too. Why would they do that? Market share? Maybe.


Or could it be using brand loyalty to improve sales?
How many products are made by one company,
yet are sold under various labels at different prices?
Cars, dishwashers, dryers...all about the money, ain't it.

I have a lot of Mini-Mags, some of it recent production, and I have yet to see dents, dings, chips and poorly seated bullets.
Winchester M-22 yes, you'll see all that and more.

No, CCI never claimed Mini-Mags were benchrest quality, but they are and always have been pretty consistent for hunting ammo.

I hear ya' sandog.

Some of us are just lucky when it comes to the rimfire assembly line lottery.
Some of us ain't.

Dents, dings, tilted seating, bullet material compressed down onto the brass.
At 25 yards it won't prevent you from taking a squirrel.
At 50 yards it'll cause an inch plus of spread.
At 100 yards y'er looking at 3 inches plus.

All about the OCD, Al.

Gives me an excuse to point out the obvious, right?

Not surprising that most folks simply load and fire as fast as possible,
then accept the blame for strays and fliers, or point the finger at the rifle.
I know I'm doing everything I can to hit what I aim at.
When I don't, I have to know why.

Good photo example of the three 22LR cartridges showing your point.
The contributors to inaccuracy that you have pointed out are obvious.

In general as well,

I might add that the different OAL of the rounds, the out of concentric
cartridges, bullet seating and misshapen and different ogive contours
are all contributors to poor performance.

The different ways that bullets enter into the throat or lands is extremely
variable. The minute and slight differences in angle of the bullet ogive
as it leaves the case and enters the bore, slightly different pressures due to
how much jump or contact the bullets are making with the bore.

It could be an issue of SAAMI max/min cartridges & SAAMI max/min chambers.
Any combination of the above might cause a ctg. to be a few thousandths off
of being dead straight in line with the center of the bore.

Seriously, if we obsess about these things we will go nuts. I am thankful
that the common ordinary range ammo is as reliable and accurate as it is
under the numerous possibilities to be even crappier ammo.

Please excuse me if I have intruded here with non topical musing.
