Will, I would like to respond to your message in two parts: First, I agree with the last part of your post concerning my statements about the sight alignment needing to be small compared to sight adjustments - I didn't think that through carefully enough before I posted it. I have edited my previous...

While discussing this topic on another forum, a member raised the question of why sight adjustments work if eye movement doesn't cause a shift in the Point of Aim. After some thought I gave the following reply, which I think adds another piece to the puzzle: "In thinking about your question aga...

I am re-posting the link to the paper that Doug and I wrote. The paper has been updated to include tests that use a camera to investigate the phenomenon. Doug performed all of the setup and testing, and the results conclusively demonstrate that the effect of parallax suppression is real. It also pro...

In conclusion I have to say that (in my opinion) correct and consistent sight alignment to a rifle shooter is a very important thing. Inconsistency and the inability to easily find correct sight alignment is usually an indication that somthing else is wrong with the position, and as such the import...

Robert, Was the rifle used sighted in before the experimental shots? Your mention of the shooter eye and the apeture being a "geometric" intersection, would cause us to look at the range of an error factor in a rear apeture. ... Your research would then point shooters to use a smaller ape...

Jonno, I agree with your statement about needing a consistent head position. In our paper we mention that fact. It seems that you agree that "sight misalignment" does not directly alter POI. The secondary effect of changing the hold on the rifle and its recoil behavior is nearly impossible...

Bill, I was one of the authors of the paper, and I conducted the shooting test. I have been shooting NRA Highpower for the last five years and have a Master's classification. I'm not surprised that you are skeptical. I offer the following simple experiment to demonstrate the effect I am talking abou...

Proper Use of Aperture Sights

When aiming with an aperture sights it is almost always stressed that careful attention must be paid to centering the front sight within the rear aperture. Offsets of the front sight within the aperture are said to constitute a change in sight alignment and will result in a misplaced shot. I have re...

Savage MarkII

What type of accuracy could I expect from a Savage MarkII rifle? Savage has started offering this model with a heavy barrel and peep sights. I recall reading that these rifles were originally manufactured by a Canadian company that was known for making target rifles. I certainly wouldn't expect a mo...

I finished reading (at least for the FIRST time) the section of this book dealing with prone shooting. It was better than I had hoped. Lots of practical guidance for improvement. One area that has always puzzled me was muzzle jump. I new that lots of it was generally bad, and that variation in direc...

Mike, Thanks for the suggestion. After toying with different options, I decided to get a Rimfire upper for my AR-15. I knew this would put me at a disadvantage if I ever wanted to actually shoot in a smallbore match, and I thought it would be fun to have a different rifle than the AR (I had the chan...

Marcus, Thanks for the reply. I do not plan on competing in smallbore competition. I only intend to use smallbore for backyard practice to supplement my regular Highpower shooting. I think I may have mis-stated my premise about the difficulty of smallbore vs. highpower, but you indicate that my scor...

Cross Training

I compete in Highpower Rifle, but I have recently purchases a 22LR target rifle and intend to shoot smallbore so that I can get in more practice time. The concensus from what I have read is that smallbore is more difficult to excel in than Highpower. I am wondering if this is because it is inherentl...

I recently purchased a Daisy 953. Same barrel and receiver without the wood stock or match sights. I planned to put a scope on it anyway so I didn't miss the sights. Nice little rifle. I tore mine down to work on the trigger, so I am familiar with the mechanism. One thing that I thought of is the pu...

Different Types of Smallbore competition

I am trying to understand the different types of smallbore competition available. Is it correct to say that all Olympic style smallbore is shot with metallic sights? Is there a category known as "International" (like 300m fullbore) that is different from Olympic style? I am assuming the NR...

Paul, Interesting that the barrel is shrouded. Never read about that anywhere before. I wonder if it is a tensioned barrel or just a cosmetic shroud? I found a manual for the CM2 on the EAA website. There are pictures that show the rifle with an (optional) removable box magazine. Did the rifle that ...
