Thread: CCI subsonic issues

Bought a rifle off a cobber and was able to get out and test it today.
Fired a 160 cci subs testing it and had a say 1 in 25 maybe more fire but not cycle the action. Shots hit low seemingly under charged.
You could feel and hear a marked difference when they were fired.

Otherwise they went very well and accurate as usual.
Thought maybe I got a bad batch.

Fella I bought the rifle off says he had the same issue with around the same frequency.
Anyone else having the same issues?

What sort of rifle? I've put thousands of CCI subs through my 10/22 and never had an issue with them

Doubt it's the rifle as I have had it once or twice recently in my son's 795.

Its a marlin 60 DLX suppressed.
Impact goes 3-4" low as well.
I will put them over a chrony tomorrow to make sure.

I couldn't get .22lr to register on my magnetospeed

I have an old crappy optical one for pistol loads and such😆

My V2 sees 22s no probs. But, had to adjust bullets type to"slugs". Not sure what the V3 calls them.
Did velocity tests for maybe 8 different type of 22. Some had real shit ES.

Pull the bolt out and flat it with 1000 grit, rub down imperfections inside the receiver. Also, the heavier subs like win 42 have a bit more energy and cycle better.

Oh, and buy a marlin

Did you change the bullet material setting ?

yeah although I only tried to use it on the .22 once, and didn't spend much time mucking around with it.

my norinco bolt HATES the cci subs..they shot like crap and I wasn't impressed with hitting power on hares
the 42grn power points are in a whole different league.

Mate had a bad batch of CCI subs a little while ago. Suppose it happens.

I've noticed all the Norincos I've used prefer Winchester over CCI. Feeds better and shoots straighter.
My current 10/22 (I go through phases) prefers CCI. My first 10/22 hated the stuff.

Can't get up the range today due to weather. But it is not the rifle. It is a well maintained marlin 60 DLX.
Shoots like a small bore target rifle.

It is an under charged shell.
Bad batch I spose.
Will confirm on the chrony when the wheather clears.

How much of that batch have you got??

Weather is fairly fine up here in Gladstone (e: cloudy though, I guess it's the same down there, shit for a chrono)

One of my stainless 10/22's doesn't like CCI Subs, so I keep a healthy supply of Magtech subs handy for it, - they're not the most accurate out there, but they'll hit most things.

Rifles a lemon, send it back.
