Daystate Pulsar HP .25 and Caldwell Magnum DeadShot FieldPod

[AnimalHitman]

I just got back from the range where I zeroed and grouped my new Pulsar HP .25 using my new DeadShot. My zero was Chairgun optimal (42.9 yds). I then shot groups at 50 yds, 75 yds, and 100 yds. All groups were five shots, no mulligans ;-). I know I probably can get better groups with JSBs, but I am willing to sacrifice a little accuracy for the incredible stopping power of the H&N Hunter Extremes.

Pretty good shooting. I like the target holder as well. Where did you buy those?

Well, Crush; that's just my Primos Trigger Stick tripod w/ two-point rest multipurposed! I actually use that for hunting. I only drag out the heavy machinery for zeroing

Nice set up and awesome pup. I’d like to see you try JSBs for comparison. I hear what you’re saying about the stopping power of the H&N Hunter Extremes. However, if the shot placement is off, the stopping power is voided. 

A well placed 25.39 or 33.95 is going to drop quarry very effectively. Just my .02, take it or leave it. 

 

[AnimalHitman]

Yeah, zx; now that I have a DeadShot and can get credible groups, I'm going to try the JSBs. In fact, I just ordered a tin of King 25.29s. What kind of groups should I expect?

 

[Oregun]

You should expect groups like or better than your zero @ 50 & 75yds.

 

[AnimalHitman]

Really? That would be amazing!

I do have a question. I've noticed that when grouping, people are not aiming at the bull's eye (except for the zero). The focus is on precision, not accuracy. Is this valid?

Here is my process: When I encounter a new pellet, the first thing I do is a full-bottle shot string to get an average fps for entry into Chairgun. Then I zero at the Chairgun optimal zero. When grouping at various ranges, I use the Chairgun hold-offs with my mil-dot scope, aiming for the bull's eye. So, I'm measuring not only the precision of grouping, but the accuracy of hitting a specific aim point (bull's eye). Am I grouping wrong? 

 

[Guest]

Yes.

 

[Guest]

Let me explain. Shooting for groups is an exercise in not only your guns repeatability with a given round, but more importantly your repeatability in shooting the gun.

 

[AnimalHitman]

Why would using mil-dot hold-offs to hit the bull's eye throw a skew into the grouping process?

Please detail your grouping process.

 

[Guest]

An optometrist and psychologist would likely explain this better but our brains like things to be symmetrical and using a crosshair satisfies this. So when I shoot groups I rotate 10 or so clicks up or down so I have a clean point of aim. I try to ignore my pellet impacts so I don't try to adjust my aim.

 

[AnimalHitman]

Oh, so it doesn't matter, by definition. The cross-hairs would be at the same spot for each shot regardless. I am merely measuring both precision and accuracy at the same time. Two birds. Thanks for clearing that up.

 

[Oregun]

For me, I start off by shooting groups. Once satisfied, I'll adjust my turrets to the bullseye... in other words, aim at the bullseye and adjust the turrets to the center of the group. This becomes my zero. After that, I like to shoot onesies at each bull, unless I have a flier or make a mistake. 

I have a long way to go before I'm EBR ready.... hopefully, I'll get some good practice time this weekend.

 

[AnimalHitman]

Thanks for that, Oregun

 

[Oregun]

No problem, AH!

I'm learning a lot. I shoot with my buddy @dwilson050. Dave started air-gunning for the 1st time, last Dec. He's an excellent shooter (former Marine/always a Marine). 

If you look at the bottom target, you can see a solid line. Usually, we start by shooting at a vertical line (not horizontal as pictured)... to get our bearings/aim point as John-in MA points out. This is another discipline that Dave has thought me. After these three processes, we're ready to shoot!

Carl:

So you don't see any problem with using Chairgun mil-dot hold-offs to group after the scope has already been zeroed, right? It's merely combining both precision and accuracy.

 

[Guest]

Precision is a measure of the guns repeatability, accuracy is a measure of how well you shoot a repeatable gun.

 

[AnimalHitman]

yes

 

[Oregun]

Precision is a measure of the guns repeatability, accuracy is a measure of how well you shoot a repeatable gun.

Indeed. You can use anova gauge R&R to measure repeatability and reproducibility of you and your set-up... if you wanna "geek out"
