I have owned a 452 varmint in HMR for 15 years or so. Always thought that by rimfire standards, it was a fairly accurate rifle, especially at longer ranges. With match ammo, both my Kidd and Anschutz will outshoot it handily at 50 yds, but not at 100 yds or more. That is where the CZ excels, pretty much MOA with most polytip.

TNT and XTP, the most accurate and you could expect 0.40 groups

I was wondering if a HMR load with a 25 grain bullet from a WSM would work well. Just looking for the best combo that does not field dress the game for you.

"TNT and XTP, the most accurate and you could expect 0.40 groups."
"At 100 meters"

Nope.

That is hard nope with a period; although I do agree that TNT and XTP/Game point are the most accurate on average.
Makes no difference what brand, because CCI makes all of them on the same machines, with the same components, powder, primer mix, with just the tip color being different on the V-max's.

All you have to do is check out this RFC link to see how rare a .40 group average is at 100yds, let alone 100 meters.

And yes, I know this thread is almost a year old.

LOL, good catch. I think I read this thread last year and just kept scrolling.

This weekend I was testing an Anschutz 1907 that seems to have a very good barrel. Conditions were good and so I was getting 'one-hole' groups at 46y. So, let's say 1/4 moa. Even though I don't target shoot, I'm already planning to make the pilgrimage to Lapua testing in Ohio and find a case of ammo that really sings in tune with it. It's the least I can do.

A couple of guys showed up down the line and after introductions one of them admitted he was completely new to firearms. When they asked how I was doing I said pretty well, because this rifle is shooting one-hole groups. He seemed amazed and asked how far the targets were. (They were right *there*, not far away). "Is that 200 yards?". I politely answered "50 yards". (I also knew right then that he wasn't a golfer)

This reminded me that not everyone has a firm realistic grasp on the three variables of accuracy: actual size of a group, actual repeatability of a group, and actual distance.

I sought out an 18" barrel based on this kind of data and wound up with a Ruger Predator. Notice that barrels longer than 18" (1) don't make more velocity, and (2) are less consistent.

My gun has been consistently a 1.5moa with ammo it likes... Either the 16gr leadfree or the 20gr FMJ. Sometimes it'll shoot sub-moa, sometimes over 2.0moa, but typically 1.5moa or so.

Having run various loads over a chrono, the 16gr leadfree and 20gr FMJ were more consistent than the other loads (at least the lots that I have).


Given that the gun cost $275, shipped, and the ammo costs <20/round, I'm quite satisfied with 1.5moa...



To the OP: Just buy a box or two of each available load (there are really only a half-dozen or so), and try them all.

When you find one that your gun likes, then buy a couple thousand rounds and call it a day...

Having shot every iteration of 17HMR ammo through 3 different rifles, I remain convinced that the quality of the rifle comes first and the quality of the ammo, while important, is second. My Anschutz 1517HMR simply shoots better than the other two. Mind you, a 3 rifle comparison is hardly definitive, it cannot be coincidental that the same rifle produces the best groups, regardless of ammo, every time.

I agree.
A poorly made rifle won't produce consistent trajectories, not even with match ammo.
On the other hand, not even the best rifle can make cr*p ammo shoot bugholes.
And even a great rifle and ammo, in unskilled hands, isn't going to do so well.
Need all three legs of the tripod to get 'er done.

Got to keep the barrel clean ...

The .17 HMR has a jacket and the barrel will pick up copper. Being a small diameter, it adversely affects accuracy sooner than with larger diameter rifle barrels. Clean often and well. My experience.
