after owning and selling 2 hmr`s (cz452 and a 1517 thumbhole) ive always fancied a 22 wmr

 

They have a place, as does the HMR etc etc......

 

I like mine, and as I always say, "it gives me a feeling of confidence", and the 30g V-Mag is excellent for my requirements!

 

...and some people are getting their wires crossed, the HMR is less effected in the wind than the WMR, and retains its energy better at looooonger range, look it up yourself!

Deker your right all bar the energy bit.

 

From Hornady Website, like I said, look it up yourselves!

 

HMR17g V-Max Muzzle 245ft lb, 100 yards 136ft lb, 200yards 72ft lb Energy loss in 200 yards 173ft lb

WMR30g V-Max, Muzzle 322ft lb, 100 yards 134 ft lb, 200yards 67ft lb Energy loss in 200 yards 255ft lb

In the above case the HMR delivers more energy at 100 yards than the WMR which started 77ft lb more!

 

The 40g WMR isn't quite so bad but still sheds energy much faster than HMR.

Cheers for that. was an interesting read, its a good reason to leave them alone for a few more years, these problems always get sorted out in the end so in the mean time HMR owners beware !!

[Deker 3,478]

The 40 gn .22wmr defo has more energy up to and slightly past 100yds.At the BASC open evening I attended alot of the audience reported the same problem i.e that the hmr was getting a round lodged in the barrel and if a second round was subsequently loaded and fired the magazine would blow out or indeed barrels have exploded!A theory as to cause is the powder in the case is being contaminated by water or oil and failing to burn.The primer detonating is enough to force the bullet into the barrel but no further!Then bang!Same scenario as 12/20 bore mix up!

 

HMR has ongoing ammo issues, it is well known.

 

I have no argument with this and evidence has been shown of mags blown out, as regards EXPLODED barrels, you are in the land of the fairies, show me one!

I had never realised the two rounds where so close together. but i must admit i was surprised to see that the WMR regained its composure after 200 and held its energy at about 20 or so ftlbs more than the HMR. doing a comparison an interesting point is that the .22lr carries more energy than the HMR after 220yrd, not that you would be shooting a 22lr that far, interesting though

In the land of the Fairies??Stupid comment I live in the LAND OF DRAGONS!, read the post on SD! 40gn .22WMR does out do 17 hmr at 100yds.

Energy

Velocity is an important factor in calculating kinetic energy, but so is bullet weight. We have already seen that the .17 HMR is by far the faster cartridge, but the .22 WMR shoots a far heavier bullet. Energy is important because it powers bullet expansion and penetration, and is a major factor in killing power.

Here is the energy of our comparison loads, in foot-pounds at the muzzle, 50 yards, 100 yards, 150 yards (when available), and 200 yards (when available):

• .17 HMR, 17 grain V-Max = ME 245 ft. lbs., 185 ft. lbs. at 50 yards, 136 ft. lbs. at 100 yards, 99 ft. lbs. at 150 yards, 72 ft. lbs. at 200 yards.
• .17 HMR, 20 grain XTP = ME 250 ft. lbs., 187 ft. lbs. at 50 yards, 137 ft. lbs. at 100 yards, 99 ft. lbs. at 150 yards, 72 ft. lbs. at 200 yards.
• .22 WMR, 30 grain TNT = ME 325 ft. lbs., 200 ft. lbs. at 50 yards, 120 ft. lbs. at 100 yards, ft. lbs. at 150 yards.
• s.22 WMR, 40 grain JHP = ME 324 ft. lbs., 230 ft. lbs. at 50 yards, 162 ft. lbs. at 100 yard.

Here we see a different story. The .22 WMR starts with about a 75 ft. lb. advantage in kinetic energy at the muzzle. At 50 yards the 40 grain .22 bullet is carrying about 45 more ft. lbs., and at 100 yards the 40 grain .22 bullet still has a 25 ft. lb. advantage over the .17 bullets. At 150 yards the .17 HMR has an energy advantage of about 20 ft. lbs. over the 30 grain .22 bullet, and we have no figures for the 40 grain bullet beyond 100 yards.

What we can conclude from this is that the 40 grain .22 WMR load is the most powerful cartridge out to at least 100 yards, and beyond that adequate data is lacking. I would guess that the 40 grain .22 WMR bullet retains its energy advantage out to at least its maximum point blank range of about 125 yards.

Note that the energy of the 30 grain .22 bullet falls behind the 40 grain .22 bullet by 50 yards, and behind both .17 HMR loads by 100 yards. Also note that there is no practical difference in energy between the 17 and 20 grain .17 HMR bullets at any ran

Thank you for confirming what I said......

 

"....and some people are getting their wires crossed, the HMR is less effected in the wind than the WMR, and retains its energy better at looooonger range, look it up yourself!"

 

Your examples above

HMR 17g energy loss at 100yards 109ft lb

HMR 20g energy loss at 100yards 113ft lb

WMR 30g energy loss at 100yards 205ft lb

WMR 40g energy loss at 100yards 162ft lb

 

I'd say that shows very conclusively that the HMR retains its energy better!

 

Edit, any time you want to show a blown up HMR barrel feel free and I will apologise, until then live with the fairies.

that was fairly rude !!!!!

[roe-buck 63]

I think you have your wires crossed those figures of mine are retained energy not energy loss, the 40 gn 22 wmr has clearly got 25 ft ib of energy more than the 20 gn 17 HMR at 100 yds!What we can conclude from this is that the 40 grain .22 WMR load is the most powerful cartridge out to at least 100 yards, and beyond that adequate data is lacking. I would guess that the 40 grain .22 WMR bullet retains its energy advantage out to at least its maximum point blank range of about 125 yards.

Please READ my post, you have confirmed that whichever way you want to look at it the WMR sheds energy FAR quicker than HMR.

Did I say anything about which was the most powerful, (even though the HMR is often more powerful at distance), I SAID ...and retains its energy better!

 

Your examples

HMR 17g energy loss at 100yards 109ft lb, that is 245-136ft lb. Retained energy at 100 yards is 55.5% so energy loss is 44.5%

HMR 20g energy loss at 100yards 113ft lb, that is 250-137ft lb. Retained energy at 100 yards is 54.2% so energy loss is 45.8%

WMR 30g energy loss at 100yards 205ft lb, that is 325-120ft lb Retained energy at 100 yards is 36.92% so energy loss is 73.08%

WMR 40g energy loss at 100yards 162ft lb, that is 324-162ft lb Retained energy at 100 yards is 50.00% so energy loss is 50.00%

 

In all the cases you quoted the HMR retains its energy better than WMR, put another way the WMR sheds energy quicker than HMR.

Well to my mind at all practical ranges for Fox with a rimfire I would choose the Magnum.Lots of people actually seem to be reverting to that if they don't go the centerfire route,which is more practical for serious Fox control anyway.

I have no idea of any .22lr, HMR or WMR figures over 200 yards and as you say they should be of no practical use to anyone, but out of interest what is your source of this information?

We seem to move on then!

 

Do you have a WMR and a HMR? What experience have you had with them both on Fox, with what ammo at what distances in what situations?

 

I have a lot of rimfires and centrefires and Shotguns and I do a lot of serious Fox control, there isn't "a" rifle, "more practical for serious Fox control" , every situation is different and I do my best to take out the rifle best suited for that situation.

 

Fox and .22lr

 

Fox and HMR

 

Fox and WMR

 

In these cases they were all stopped with the rifle "more practical for serious Fox control".
