Scott, on pressure ranges consider this: At sealevel (29.92" standard) you hardly ever see a higher pressure than 30.60 in. You Seldom see a lower pressure than 29.50 inch. When you do see a lower pressure, it's with a tornado passing over you or you're in the eye of a hurricane. The...

Wow, so many ways to go on this.... From my experience of about 25 years with an original Chrony and more than that with your exact load: This load should give about 2640 fps. It's a great match for Fed GoldMedal Match (at least, as the factory loaded in mid 90's.). In a factory Remington...

Re: CZ 452 American Low Rings Needed I'm sorry this isn't a direct answer, but a word of caution. Everyone I know, and about everyone on rimfire central has had the same problem with trying to achive a low mounted scope on a CZ 452. That is Bolt handle clearance with the scope. It's caused...

Re: .17 HMR at 500 and 800 yards (video) CZ 452 VYD: You don't understand the "count". "1" is NOT "1 one thosand"--or 1 second as most often done. "1" is about .1 seconds. So you are counting from 1 to 10 over a time interval of One (1) second. As far as the method working, again, it...

Re: .17 HMR at 500 and 800 yards (video) CZ 452 I don't WANT to answer this, I'll only look like a smuck, but... Ask yourself if the shot to 500 yds is doable. I think, yes. With a 100 yd zero, and using a CONSTANT G1 BC of .125 (pretty well established as good for muzzle to 200yds, but a...

Re: I hate mirage Skinnypitt: No, I don't think you have it. What your are doing is putting your crosshair or front sight on that "closer" (understand 'other'/NOT TARGET you're actually hitting/shooting) and putting a sight correction on that is so gross you're hitting your target. Bryan's...

Re: Ballistic coefficient For L.C. use Sierra's numbers: .490 to 1000 IF you're only using one number. That's a G1. IF you have a program that will handle multiple BC's then Sierra publishes .505 above 2800 fps; .496 from 1800 to 2800; .485 below 1800. My older Sierra III only handles 3...

Re: I hate mirage Shane, you always come up with the perfect illustration! Bryan, we used "offset bombing" often in the Air Force. When you had a radar "no show" or a target that would appear late in the run, you'd update the navigation solution by placing your cursors on a good radar (or...

Re: Range Report. Lot's of load data and questions. Erik, nice report. Lots of data to consider. Did the "weird" group that "shot lower than the previous group" on day one reoccur on day 2? Just interesting... I've seen lots of rifles have their group POIs 'wander' in unexpected fashions...

Re: $99 Vortex Crossfire Range Report I kinda think we're killing this scope with lack of details and poor word choices in our posts. Mtneer What is "tunnels" at the higher powers? TargetTerror and Mtneer: What is "contrast issues" at the higher powers? Do we really mean "contrast"...

Re: $99 Vortex Crossfire Range Report McKinneyMike How do we KNOW how many are "out there"? If only SWFA is selling them, for about a year now, it wouldn't seem like there could be a great deal of them. SWFA should know almost to the exact number how many are "out there". But without...

Re: $99 Vortex Crossfire Range Report LoneWolfUSMC: Please fill in a couple "holes" in your report. What cartridge/load are we talking about in this 40 XB? And at what range?

Re: Varget Temp sensativity 1. Post the Lot Numbers of your 1st and 2nd "cans" of VarGet 2. It would take 45 mph of Cross Wind to get 3.5 inch of displacement---lets FORGET he can't tell the diff between Calm and that! 3. How long are you waitin between shots? What does the barrel feel...

Re: balistic data card question?? The answer is the same as the above, centerline to centerline. The technique of finding it is different. I put a cleaning rod down the muzzle and into/through the action. Use my calipers to measure from the bottom of the cleaning rod to the top of the...

Re: Range Estimation Tutorial Line starting with "We will use the "Army" Change "MAY other makes" to "MANY other makes" (all caps to pinpoint attention only) Good Read. It might complicate the article past an "intro" level, but you might consider expounding on taking ranges based on...

Re: Which rangefinder, Leica 1200 or Bushnell 1500 ARC Wow, once again it's impressed on me how BADLY we need a set of STANDARD TESTS and "Targets" for LRFs. I have a Leica 1200 SCAN. Been using it for almost 2 years. I'm disappointed in it. Unfortunely there is always a bell curve of...

Re: Rifle age..your thoughts I'm reading your post as a "safe service life" type question. The practical answer is age makes little difference. Things to consider: "modern Steels" are AFTER World War I--say 1920. Before that composition specs and heat treatment varied quite a bit...

Re: Mounting a scope sideways.....On purpose!? Yes, rotating the scope so one know sticks out to left works fine. It can even work if one knob is sticking DOWN if you have short turrets/adjustment housing OR an offset scope mount, and even with side focus. Fat fingered people can read...

Re: Weapons failed US troops during Afghan firefight Grounds keeper: "Some of what I ask is based on the fact that by age 8, I knew more about shooting than I ever learned on active duty. And I had access to pretty much any weapons I wanted, small arms wise. And yeah, it torques me that we...

Re: Parrallax with non AO scope Boltstripper gave the kernal of the answer. It can't be answered exactly. It also shows you need to find out what parallax is and what causes it. Read this by an Optics Engineer: http://www.snipercountry.com/Articles/Parallax.asp when that is committed to...
