anschutz 1516 17hmr 20gr vs 17grn

[Prebanpaul]

So I bought a very little used Anschutz 1516 with the two stage trigger adjusted down to three ounces in 17 hmr. The scope that I have is a Nikon target dot prostaff 4.5x18. This scope came with the gun. I fired 4 shot groups as that is what the magazine holds

First set of groups where shot with hornady 20 xtp at 100 yards

2.037
2.279
1.143 average 1.819

2nd group was with Winchester 20 grain xtp

.644
1.043
1,187 average is .958

I was Extremely Disappointed in these groups, it was a perfectly calm 65 degree day today.


So i had time to run one more set, I had a box of Hornady A17 in my range bag and pulled it out.

First round was a called flyer, the group measured .88 with the flyer with out .227
next group measured .225 so if you take out the called flyer that was 7 rounds at .226.

This thing is a shooter. I cant believe that the cheapest hottest rounds out there work ridiculous in this gun. The guy I bought this off of has the exact same model in 22lr. Cant wait to get me hands on it.

18 inch barrel threaded for can,with the two stage trigger.

The only way I can understand rimfire target results
is to use a ballistic chronograph every trip to the range.
How else can you determine if it was you or the rimfire ammo quality?

7 shots at .226 is me and great quality........

Annies are usually great shooters. Still, I would not judge any used gun on only 7 shots. Clean the bbl very, very meticulously. Then foul it with 5 shots. Then shoot 6 or 8 5 shot groups. Statistically, that will give you a better idea what to expect. It could be that the Annie's rate of twist on the bbl is not calibrated for the 20g ammo which was not around when the 17hmr first appeared. Those heavier, longer bullets need more twist to stabilize and may not work in your rifle.

Have fun

My 1517 HB likes CCI and Hornady.
When Lapua and others like them get into the 17 market we'll see some improvements.

I shoot a lot, I will shoot 5 shot groups when I get back. I have been behind rifles enough to recognize a shooter. I will post pics when back from SW Florida

Would love to have Lapua 17hmr and 17wsm ammo.

I had the same experience with the A17 ammo. Bought a bunch from the same lot and called it good. I would love to see someone pick up the ball for match quality .17hmr ammo. Just think of what these little guns could do with that!

 

[Prebanpaul]

well first shot once i got back killed a ground hog at 227 second shot 177. So its two for two on groundhogs.

 

[Prebanpaul]

So I was asked to shoot five shot groups, and had the opportunity on Friday to do just this. Changed out the scope for the Weaver tactical 3.x15 FFP. Largest group shot was .334 3 more groups largest was .224 smallest .197 This thing Fing shoots.

 

[Tucker301]

I'll theorize that the A17 is loaded with more powder than the rifle can burn, so you're getting consistent burns every time. I have some of that ammo and will try in mine soon. My CZ 455 has me considering selling the Anschutz anyway, so perhaps this will give me a reason to hang on to it.

 

[Prebanpaul]

keep me informed on how you do. I bought this gun based of a test that I have read on two different rimfire, 22 and 17 that both stated that an 18 inch barrel is the optimum barrel for SD. This might be the most accurate 100 yard gun I have. LOL

 

[Tucker301]

It won't be today. The wind is blowing rocks around out there.

 

[justin amateur]

Okay, barrel length affects standard deviation?
How can that be even possible?
Friction doesn't have any effect on SD that I know of.
SD is a calculation based on a sample of measured mv's.

Somebody needs to try and explain that one.

I've been shooting across a chronograph for a while,
the only way I can minimize the SD is to hand load center fire
or use a sample so small as to be statistically useless.

 

[Prebanpaul]

Well since your not hand loading 17, you have one constant powder charge. Basically you cant change that variable. Just like with any other specific round you will have a length of barrel that will control the speed. For example most times an 18 inch barrel will produce a slower round than a 22-26 inch barrel (I am talking generically for all of you that like to argue) So by controlling the barrel length, you control the speed of the round. What it appears in my rifle is that I am getting the most consistent powder burn out of my 17. Consistency is the key. Just google search best length barrel for 17 and 22 caliber. You will see the research that I read. Both times 18 inch barrel produced the lowest SD's with the control barrels.

 

[justin amateur]

I read the articles as requested.
My problem is with the conclusion drawn
based on the number of shots fired.
Not enough shots recorded to provide an adequate sample for analysis.

I've seen several people mention this ammo. I'm going to hve to pick some up and try it. A few of my .17's love the VMax and others prefer the TNT...none of mine shoot the 20 gr as well.
