Why?

minktrapper · 10-06-2021 6:59pm

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

Bog Trotter99 · 10-06-2021 8:41pm

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

minktrapper · 10-06-2021 9:07pm

Easy enough to buy them in Ireland.

BSA International · 10-06-2021 10:34pm

✋

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 · 11-06-2021 8:42am

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

CZ452.

Steady 1.5" at 100 yards.

minktrapper · 11-06-2021 1:37pm

How much would the drop be at 120yds.

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

minktrapper · 11-06-2021 2:15pm

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.

Feisar · 11-06-2021 2:30pm

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 · 11-06-2021 7:24pm

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?

minktrapper · 11-06-2021 8:46pm

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 · 11-06-2021 9:24pm

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.

BSA International · 12-06-2021 12:25am

.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 · 12-06-2021 5:36am

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 · 12-06-2021 9:12am

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 · 12-06-2021 10:42am

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 · 12-06-2021 11:11am

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.

Or he knew that just over 40 years later there was going to be a .17hmr...... sorry a 'shoot flatter' .17hmr.:p

minktrapper · 12-06-2021 2:11pm

Just gave a look at the Cartridges of the World book. There was a .22 Extra Long. Introduced around 1880. Now obsolete. It used the same outside lubricated 40gr bullet that was later adopted to the .22Long Rifle. More powerful than the LR but not but not noted for accuracy. Loaded with black powder. All of 6 grains. Was advertised as a 200yds target cartridge. But would not qualify by today's standards.
Any rifle chambered for it could load and fire a Short,Long or Long Rifle. Not suitable for high or hyper velocity cartridges as the chamber might not be strong enough.

There you go a possible reason.

There is a whole lot of science goes into a bullet and suitable gun.

The weight of the bullet can affect the amount of pressure that builds up as it is fired. The twist has to be correct for the speed and weight of the bullet.

minktrapper · 12-06-2021 4:37pm

At 140yds there is a 40lb difference in energy between the 30gr and the 50gr. Which is considerable in my opinion.

Like Feisar said it's not a heeled bullet like the 22lr it sits in the straight wall case like a .38 ,45-70 etc
Also for the thickness of the brass pick up a .22lr case and a .22 magnum case they're thicker brass make the brass that thick on a 22lr you lose case volume
Though they could've just made it a little larger to make up for that ....
Could be to do with getting a more positive extraction on the larger rim

Actually the .22lr extra long is still made although with a 32grain bullet instead of 40 to fit in standard chambers
The casing on a CCI stinger or segmented hollow point is not a long rifle case it's a "Extra long" case
