Thread: Winchester 22LR Subsonic Hollow Point Chronograph results

I had the opportunity to put some Winchester 22LR Subsonic Hollow Point through a chronograph today, these were the results


1056
1061
1029
1043
1014
1044
1046
1071
1003
1019
Avg:1039fps. Box states 1065fps.

Not too bad being 25-30fps shy of the advertised velocity.

Well you wouldn't want it over its advertised velocity.

What barrel length and action style where you using?

Fired through a bolt action JW15a with a 11" barrel and full over barrel suppressor

I used to feed them thorough my 10/22 and they cycled no problem

Ok well that makes them cheaper than CCI Subs and hopefully easier to get ??
I have had a play with CCI Stingers at 75 yards with reasonable grouping but 2" higher, as expected, but was surprising at 1" to 2" the right of the settings that I was using for the CCI Subs.
Shooting 10/22.

So in your average length barrel they'll do more or less exactly what it says on the packet. I'd be keen to see what ammo from same batch do, say in a shorter semi vs a longer bolt action.

If someone wants to bring round their choice of arms we can give it a go.
These have always been very accurate and reliable for me and I think the consistency shown proves why. Is cheap enough and readily available not to need to change to anything else so if it ain't broke.......

Well that sure shows you don't lose much with a short tube with that ammo!

It's well known that rimfires don't require long barrel lengths to achieve their max vel. Traditionally, 16" was quoted as the length where vel maxes out and in fact longer barrels can deliver lower vels.

I recall reading not so long ago someone getting useful vels out out a very short rimfire barrel, maybe 10"

My Marlin 925 loves these....that 42g thud when it hits a possum is something special.

Gotta love those 42 grainers especially the high velocity ones
