HM2 long range?
 
I like to shoot rimfires on steel at 200-300 meters. I have a Remington 540x that is begging to be built into a custom HM2. Can the HM2 be effectively shot to those distances on steel? Is the ammo consistent enough and the bc of the bullets good enough for decent hit percentages on 2MOA targets at those distances?
I have never owned an HM2 so I am asking from a perspective of true ignorance.

If you get a good lot number of ammo that is accurate they shoot good. Your distance is pretty far, I did several years back shoot a marlin at 200 yards on paper target and it shot well. Some of the recent ammo I bought was very poor accuracy wise. It does not matter how good your gun shoots if you can not find consistent ammo.

Inconsistency of performance is the Achilles Heel of Mach 2 ammo. I personally would not have faith in it as a long distance round. That said, I have made some very long shots on squirrels, 90-125yds.

I'm getting keyholes at 200 yards with my 17hm2. Several others have also mentioned this with theirs. It's a light bullet that is effected by the slightest wind and other environmental influences. My theory is the projectile becomes unstable when it goes through the transonic stage somewhere between 180-200 yards.

At those ranges I'd look at the 17wsm. Mine works well out that far.

My Cooper key holes at 200 yards

Thanks everyone. I am taking your collective advice. I will stick to 22lr for rimfire long range shooting.

My 17 HMR on the other hand doesn't go transonic until about 300. For farther, I have a 17 Hornet but that's centerfire.

Thanks for some good information. I have been trying to decide what scope to put on my FV and 180 yard max makes a difference not that I am likely to shoot that far but you never know. I am trying to get the weight down and a 6 oz lighter scope is a good thing.
I checked the weights on Boyds stocks and the Rimfire Hunter looks like the lightest at 2.4 lbs. The plastic stock weighs 2 lbs. Have to see how it shoots.

When the hm2 came out in 07' I bought a savage markII and installed a 20moa mount and Mueller 6-24x. I was able to easily drop them in with a mil-dot recticle on a large stump 350 yards across a lake. However that gun was sub MOA with the first batch of Eley that came out and would occasionally clover leaf at 100 yards. I am sure the 21.5" barrel helped but I was still having to aim up 5-6 feet to get there. It probably wouldn't be able to do it without a 20moa base. A 17WMR would have less drop but I find the mach2 more accurate. I don't see why it wouldn't be more accurate than a 22lr. Especially at those distances.

There was a guy by name of Kiwishooter, or something like that, that has many YouTube videos of long distance shots with his Savage 17hm2.

17M2
 
I have a Sav MkII in 17 Mach2 also. It is fitted with a 4-16x Zeiss optic. I have shot it several times at 230y and it seems as accurate as my other 17's at that distance but the bullet drop is significantly more than the 17hmr. The 17WSM is point blank at that distance when zeroed at 100y. I was only plinking at clay birds so I cannot tell if it was keyholing. Going trans sonic will upset the round but that transition alone should not cause the bullets to tumble. Wobble perhaps. I was consistently hitting 2" & 3" shards of broken clays with the M2. Not every shot but most of them.

What twist is your barrel?

Long
 
I hit a prairie dog at just over 300 yards (laser range finder) with a converted 10/22 in South Dakota about 5 years ago. Took just under a full box of ammo before I hit it. I think the bullet came down, hit it on the top the head, and knocked it out. Please note I did not say "I killed" the prairie dog because it fell behind a burrow and I couldn't see it. Actually, I'm not even 100% sure I hit it. It may have fallen over laughing at me. I'd consider it the unluckiest prairie dog ever if it was killed by the shot. :o

Short version: Nah, I don't recommend the HM2 for long range shooting.
