    Concentricity

    Re: Concentricity The runout will get better after firing the brass and even better after firing it again. All my new brass has runout usually around .001-.005 with Lapua brass and .001-.008 with Winchester brass at first but that is cut in half usually after 1 firing and again reduced after...

    Spin drift

    Re: Spin drift Yeah So what you are obviously saying is no wind dope and spin correct only, yeah?

    Range Report Chronograph accuracy question

    Re: Chronograph accuracy question I spoke to the owner of CED (Charles Hardy) about this. He spoke with one of the engineers about the spacing of the sensors on the bracket. The engineer responded that the sensors need to be precisely 24" apart as that is what the calculations are based on. I...

    Spin drift

    Re: Spin drift FWIW, today we shot @ 705 yards. I shot first @ 100 to verify the zero and then to 705. First 5 shot group was about 3.5" right with a 3-5 mph wind from 12 o'clock. I corrected .5 moa left and second 5 shot group was on bullseye. <div class="ubbcode-block"><div...

    Range Report Itouch BulletFlight questions?

    Re: Itouch BulletFlight questions? Thanks, I tried to send an email thru the link on BulletFlight's website, but I couldn't get it to go thru. RSilvers is a member here, but he doesn't accept pm's. It would be nice if he seen this and responded.

    Range Report Why density altitude?

    Re: Why density altitude? Thanks Lindy for a great explanation. I believe I will go ahead and get the 4000 so I can build a DA dope table for backup. <div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Lindy</div><div class="ubbcode-body"><div...

    Range Report Why density altitude?

    Re: Why density altitude? I would not think pressure, temp and humidity would change that much, that fast, but I may be wrong. I just loaded bulletflight on my Itouch and it doesn't have an input for DA, just pressure, temp and humidity. Is DA more accurate than inputting pressure, temp and...

    Range Report Itouch BulletFlight questions?

    Can I change the yardage increments on the yardage scroll wheel under the Calculate Simple tab? It comes @ 25 yard increments which I believe is too much for any decent distance. Also, if I set the app. to consider spin drift, it does not ask length of bullet or twist of barrel--should it? Fwiw...

    Range Report Why density altitude?

    Is there an advantage or reason to use density altitude. I'm about to order a Kestrel and would rather order the 3500 to save considerably over the 4000 or 4500. The 3500 does baro. pressure, temp and humidity which is what density altitude is (a combination of these three), so why do I need it...

    .338 Lapua and .50BMG chocies

    Re: .338 Lapua and .50BMG chocies I was unaware that Hornady made 338 lapua brass. I don't mind paying extra for lapua brass quality, so I will pay the difference. Thanks for the info though.

    .338 Lapua and .50BMG chocies

    Re: .338 Lapua and .50BMG chocies First reloads for my 338 lapua cost around $3-3.50 but drop considerably after that depending on how much I use the brass. I don't buy loaded rounds, but the good stuff I think is around $4-5 for the 338. I don't shoot a 50, but would imagine 80 loaded rounds...

    .338 Lapua and .50BMG chocies

    Re: .338 Lapua and .50BMG chocies I think it depends on how far you're shooting and what you're shooting. Target shooting (steel and/or paper) out to 1500 yards, and I believe you have overkill with the 50 not to mention the cost. <div class="ubbcode-block"><div...

    Spin drift

    Re: Spin drift DaveV, if it's very calm, I factor roughly 1/2moa spin drift starting @ about 600-700 yards. If the wind is blowing over 5mph, I focus more on trying to figure it out than spindrift. Some say it does exist, some say it doesn't. I believe it does based on my experience, but my...

    6.5x47 barrel length vs velocitys

    Re: 6.5x47 barrel length vs velocitys Go check out some of the guns of the week over @ 6mmbr.com. There are several 6.5x47's to read about. Zak Smith has a really good article about his AI 6.5x47. I get around 2940 with the 130's and 2850 with the 140's. I did try RE17 with the 140's-I got...

    Difference at 100yrds?

    Re: Difference at 100yrds? DirtyRod, if you don't want to do the reloading route yet (you will later!), do a search on the net for Federal Gold Medal Match 168 or 175 grain match ammo. If your not shooting farther than 600 yards, get the 168's, past that 175's. I reload for all my guns except...
