i been reading all over the Bull's Eye Pro website trying to find out just how much BOOST can be had, i'm sure the 3x and 4x won't boost a 24x weaver up to 72x and 96x..they seem to avoid the subject.

anyone use these things and which one would help a weaver v24 the most ?
 
accurate shooters

ok..found another site that says boost 30%..are they the cat's ass or snake oil ?:D
 
i found and watched the instructional video..duh..answers most questions but
brings up more...

like they said the ultra brite was for rimfire shooters and the multi coated for centerfire that deal with mirage, well i shoot rimfire and have had to deal with mirage both indoors and out, it speaks of a thin black line on the edge
of the mirage.....is this line always visible in the lense or just shows up during
a mirage condition:confused:

call Gene Davis, save yourself a few bucks and he'll give you the correct answers. they do not boost 3 power, they boost approximatly 30%. a 36x would be boosted to 47x and a 24x to 31x.
 
Power booster

I've tried them .....in low light conditions I found them darker than a regular scope.......our summer rimfire league finished at dusk, bright sunshine they were good.

Where did you find the instructional video? Can you post the link?

Thanks,

Gene told me a 3x would add 3 more power - a 36x weaver with a 3x booster would be 39x. What ever booster you buy just add that number to your scope. Got the info from Gene Davis when i bought mine. They work ok but i didn't like loosing my lens cap and didn't want to take the booster on and off so i don't use mine every often. Jack Chastain
 
Have a look at Video #1 on this page:

http://www.bulzeyepro.com/media.php

About nine minutes into the video a caption comes up which states the 3x booster enlarges the image by about 35-55%. I have my doubts about this, 15 to 20% would seem more accurate.

The Bulzeyepro does darken the image, which can be an advantage or not depending on the conditions. It also increases the width of the reticule, so worth keeping in mind.

Brian, the reason they show a 35-55% depends on the grinding/polishing and field of view of your particular scope. the booster will change the width and focus of the reticle, but remember the only function of the ocular adjustment is clarity of the reticle and plays no function on ao adjustment.

Jack, I bought 2 from Gene and he was very thorough with his explanation and that explanation did not include increasing by 3 power only.
 
Yes Earl I used one last Season

Yes I used an optical booster. I used the 4x. The boost is .4 x 24 or 9.6 gain. 24 plus 9.6 = 33.6 total. Very good set up!

Also I am reluctant to use stronger firing springs. Neil Stepp AND Glen are worried that the harder zap will set up vibations. I switched my Annie 1607 back to a stock configuration because of this concern.

Regards, Bruce

replace those springs. all 5 of the factory springs in my cz's varyied in length by .090. can anyone tell vibration differences in those skinny stocks? I don't think so. sometimes people think too much, change those springs your competing don't take a chance..
 
Martin you and Bill Calfee are in agreement

" Calfee: Friend John
Friend John:

Friend Scott has given you about as good an answer to your question as one can. You might go to Snipers Paradise, click on articles for the year 2004, then click on "Partners in Crime"

This is a Precision shooting article I did about rimfire ignition. It may help you.

A real short answer to your question would be: Stronger ignition, when done completely safely, works much better than weak ignition. You want as big, and deep, a footprint, striking just inside the rim, that is also safe, that your firing pin system can give you. Let me emphasize the "safe" part. (no sharp corners or pointed pins tips, nothing that could cause a case rupture) You might read the above article, it talks about some of these things.
Your friend, Bill Calfee"

Amazing Bruce:D

We would both agree that the picture shows acceptable striking force after the modification. The pin should strike just inside the rim.

Bruce,I printed off your reply, last meeting of the tooners prior to spring break. our research and topic of inventing and use of a reverse taper barrel has pretty well established that the position shooters were first to use such and being well established that a patent for a tuner was first filed in the 1950's we are looking for new material. hope your kicking the pneumonia.
 
Bruce, as an FYI, if you check i think you will find he's talking about the inner radius of the rim not it's outermost dimension. The theory, I believe, is to avoid any part of the rim radius which will vary as to how much it work hardens under forming. A pin the hits regularly into that radius will vary as to depth of strike...i.e. inconsistant ignition.
