Why?

minktrapper

Just wondering what kind of range they had on foxes.bullet drop etc. Please disregard the thumbs down.

Bog Trotter99

Never even seen them except on Youtube where i think they dropped a couple more inches over 100 yards I think.

minktrapper

Easy enough to buy them in Ireland.

✋

I've used them.

Very accurate. Out to 100ish yards not too dropy zeroed at 50 yards drop approx. 1 inch ish at 100 yards. Hit HARD. No runners.

minktrapper

If you zeroed it at 100 yds what would they like. What rifle were you using.

CZ452.

Steady 1.5" at 100 yards.

minktrapper

How much would the drop be at 120yds.

About 1.5-2" (my barrel is 16")

minktrapper

What kind of group were you getting at 120 yds can you remember. Any idea as to the twist in the barrel. I presume they can be fired in any rifle chambered for the 22 WMR.

22 LR/WMR are usually 1:16 twist.

Sorry, not grouped it on paper over 100 yards and seldom use it over 90ish yards but few times I have I use Kentucky windage of a few inches which had always done the job.

Apart from RWS 40 grain they are most accurate in my rifle.

minktrapper

Never came across RWS 40gr. I was hoping to use them out to 130yds if they grouped ok and bullet drop was not too excessive. I would think they would have great knockdown power.

Would that extra 10 grains make that much difference over 120 yards?

At the moment I am using Hornady 30 gr vmax. So I would be looking at a 20 gr increase. They shoot the tightest groups. They tend to lose their energy at 100 yds+. But if they are not tight grouping they won't be of any use to me.

Quick Google says these are giving out as much ft/lb at 100y and are going a bit quicker so might carry a bit more energy to your required distance.

The lighter bullets will lose their energy faster. Heavier bullets drop faster but retain their energy for longer. Drop is nothing as they all drop. Usually heavier bullets will retain accuracy unless for some reason they are not suited.

On a fox a 3" group would be ok wouldnt it?

Bog Trotter99

This fella does 30 - 40 - and 50 grain at 100 yards. Shows penetration and drop.

Just checked out the difference between the 40 gr and 50 gr on a ballistics chart. Not much difference between them. The 50 gr retains more energy. At 120yds only 11 ft lbs. But drops 1/2" more. So hard to call which is best.

.223 are starting around 50 grain with a huge difference in power. Perhaps 40 grain is the sweet spot for .22wmr?

All the info here.

Sports shop in Kilkenny, can't remember name, down the "Butterslip", only place I found 'em. Expensive, but brilliant!

Sometimes I'm all about the numbers but then realistically what's half an inch in the field? Wouldn't worry about it.

.22 wmr is not/never was a "target" capable round.

On a fox if it holds 3" and you know you're "drops" the venerable .22 wmr will do the job, in my experience.

Hornady are ****e in my rifle

Bog Trotter99

If the cartridge is loaded correctly. The rifle made correctly. The bullet made the same as any other, in other words correctly. Then any caliber is capable of tight groups and accurate enough to use in target shooting.

At the ranges for .22 target shooting, the standard .22lr is perfectly capable, so there is no need to use a more powerful round.

The difference between a .22lr bullet and a .22wmr bullet is just a few thousands of an inch. I can guess/imagine this was done way back in the day to stop Joe public easily adapting their .22lr rifles to accept the higher pressure .22wmr rounds which could result in a few nasties?

I had some Winchester .22wmr's. They are the ones with exposed lead at the tip of the bullet. They were rubbish and had misfires with them.

minktrapper

I don't know how accurate the information is on those ballistics charts I will just have to get some and have a go. Nothing like a real world test to verify things.
Interesting that bit of info on the WMR being a fraction bigger to stop people from modifying the .22LR. Could very well be true.

Feisar

More than likely an accident of design. The WMR fires a .224 bullet, like all the 22 centerfires and sits in the case. Which obviously then needs to be larger. The LR on the other hand fires a heeled bullet and as such sits like a mushroom in the case.

Bog Trotter99

I don't know if it was true or an accident, but if you think about it, the job could be done on some rifles with a hand drill and then you have a higher pressure charge and a bullet travelling almost twice as fast in possibly the wrong twist barrel?

I dunno but why in 1959 didn't the fella who designed this just make it for what had been around for nearly 80 years already? It could have been the exact same size with just a touch longer case for the extra charge. Then the new .22wmr rifles could have fired all kinds of .22 ammo, hv and subs by using the same case.

There must have been some reason.
