I ordered more Biathlon Sport to shoot this months cz 100 yard challenge again and got different lot than the one i posted pictures a few monts ago and to the challenge. It shot well.
Tried it out from 82 yards like the first one and it was terrible.
Did not expect that much variation between lots. Can't say it did groups. It was a lot cheaper than usually, so it could be old.
Y'er results with rimfire mirror mine Finn.
One box produces surprisingly good results, the next slings strays.
Doesn't matter brand name or type. Luck of the production line lottery.
The longer the distance attempted, the more the cartridge defects affect results.
On a side note, remember the Winchester M22 results?
Ran into another box being tried at the pistol range this morning.
Very unhappy shooter. Unable to chamber multiple cartridges in a row.
Took a look to see what the problem was. Excess lead squeezed
down past the case mouth creating a lump/ring around each cartridge.
Visible defect that should have been caught at the factory.
If it had been used in a semiauto, good chance of fail to seat properly and
producing an out of battery discharge. As it was the cartridges wouldn't
Slip into the cylinder of the revolver. Makes me wonder if Winchester has
given up on any form of quality control with it's 22lr production?
Here in Finland we have small markets, about 300 000 hunters, 1,5 milloin gun of which 220 000 hand guns. Niggardly folks and tens of shops selling guns etc., strong hunting culture and if you have a bad lot its not selling. So newer fall in a good offer if you don't know what you're doing.
Fortunatly found an exellent lot of sk std+, so lucky day after all. Next to do is to check if i'll find more somewhere.
Haven't we concluded that old good ammo is still good ammo?
Only if stored properly, crankster.
Need cool stable temperatures, low humidity, airtight to slow/prevent oxidation.
Keep it on the shelf in the garage, where the ammo is subject to temperature swings
and humidity/condensation, then you end up with expensive bulk ammo.
Mine is stored in three airtight locking storage boxes with large silica gel packs.
On the floor in a closet/air conditioned, temps kept between 70-78°F.
Yes i remember. I decided to stick with sk and lapua as those are good in my cz 455 and don't buy winchester or remington at all not even to my shotguns or rifle. Exept nitro steel which is a good performer in my semiauto.
Ammo & gunpowder are a lot more expensive here than in usa, even the ones produced here, so for example tenex or best rws are not in my shopping list currently
I wasn't surprised cranky. At 8 bucks a box I didn't expect anything amazing.
It's midgrade SK with another color label to allow consumers to feel they have another option.
If lot testing was available you could probably find a decent batch.
With online purchasing it was just a roll of the dice, like all rimfire ammo purchases are.
Federal 40 grain FMJ 22wmr, rated 1880 fps
made by CCI
CZ 455 SOF, Feddersen Stubby, Sinclair
First ten shots were across the chronograph
but a loose screw on a scope ring threw them way off target.
My fault for not checking during assembly after cleaning the rifle.
Figured out the problem and corrected it.
Remaining 40 shots were on paper. Dum-adze.
Typical CCI made 22wmr
7 inches spread at 200 yards, 2.3 inches at 100, 0.7 inches at 50 yards.
SK Long Range Match 40 grain 22lr rated 1106 fps at 200 yards for score.
CZ 455 Varmint, Lilja Barrel, Mueller 8-32x44 target scope, with the screws on the rings tight.
Sinclair bipod and bags across the chronograph for 10 shots with best edge scoring.
Wind flags out front but still can't seem to time it right when there's a tailwind.
51 on this target
then a 52
Followed by a 42...one shot hit 1 inch off the paper to the right...I hate tailwinds
then a 65
and then after all the practice...
72 and 2X...I figure the wind let off for a few minutes...nothing else changed.
Remington 33 grain Accutip 22 wmr rated 2000 fps
CCI product with a Remington label
The CCI manufacture code is visible on the side of the box.
455 SOF, Feddersen Stubby, Sinclair
Not bad on the horizontal spread, but the vertical and ES aren't what I look for.
I was recommended to try this by several folks, supposed to be decent 22wmr.
It's just more CCI rimfire with a Remington label, nothing special with this box of cartridges.
