    Took the Magnetospeed to the range yesterday

    Holderofthehorns, I did not see any appreciable difference on poi to 700 yds. I was impressed. I had the unit measuring underneath the bullet and have heard that it can push the bullet in the opposite direction. Maybe subconsciously I knew that and compensated for it, lol. Overall, it...

    Took the Magnetospeed to the range yesterday

    KYpatriot, The first thing that comes to mind is temperature. The powder in your rounds could be affected. But most importantly, you mentioned that all of them were affected similarly. Thats good? Just a thought.

    Took the Magnetospeed to the range yesterday

    Had a chance to test out my V2 Magnetospeed yesterday on my 7mm mag Sendaro. This is a great chronograph and simple to get data. The attachment strap gave me a little trouble, but once I figured it out, it stayed on without any trouble. I found that my once fired brass gave me a standard...

    Range Report Temperature?

    Hi George, So the temperature difference does affect my drop 1.2 MOA. I am guessing that since I loaded my last rounds at the range ( the rounds I shot at longer distances) with my pocket scale, the scale could have been off. I re-ran the number with 30ft/sec less and it makes up the...

    Range Report Temperature?

    40xs: what caliber are you shooting? Looks like my gun shot 25-27" low at a thousand, but the interesting thing was that it was dead on at 700. Maybe the longer distance played a big enough of a role to make the diffference. George63: I ran the calculations on the calculator, the computer says...

    Range Report Temperature?

    Hi SH, Last week at the range, I noticed that my 1000yd shots were falling short than previously in the warmer weather. 700 yds was on target, but I needed raise my elevation about 25" than i have in the past for the 1k shots. The temperature difference was about 50 degrees (75 in the summer...

    Signs of Brass Nearing the End of its Reloading Life?

    Range Report Can anyone explain what happened to this brass?

    Kevin I also have a question. I did a simple search on SH and accurate shooter. Seems that everything that is reported about the 7 saum is primarily focused on velocity and cost effectiveness compared to the 7wsm. My simple search did not show results of these bullets at 1k, which is what I...

    Range Report Can anyone explain what happened to this brass?

    Damoncali, I believe the team is using 7mm mag and 180 grain bullets, which I believe are Bergers. Official U.S. F-Class Open Rifle Team Website

    Range Report Can anyone explain what happened to this brass?

    Ksthomas and damoncali, I appreciate the feedback. I wish we were in a climate where I could go out and buy whatever components I want. That would be nice, but this is not reality right now. I like the 7mm mag and want to stay with it, just wish I had access to great brass as we all do...

    Range Report Can anyone explain what happened to this brass?

    Thanks for all the responses. I talked to the tech support at Hogdkin, Hornady and a local gun builder. I believe the issue came from older brass (10 yo) that I saved when i purchased the rifle, thinking one day i would get into reloading. Also, I used the directions to set my dies that came...

    Range Report Can anyone explain what happened to this brass?

    Damoncali, Good points. Thanks for the input. The theory you stated doesn't seem that far off. I am glad nothing happened besides the case indentation! I plan on buying new 7mm mag brass, cuz it was a bit scary how easy the brass came apart. That case indentation caused me to loose a nice...

    Range Report Can anyone explain what happened to this brass?

    John-K, It's a 7mm mag casing. These rounds had a slighter higher bump .005". In addition to shooting yesterday, I was hoping to fire form the brass. You bring up an interesting point: could the belt separate first after discharge causing the pressure on the out side of the casing to be...

    Range Report Can anyone explain what happened to this brass?

    Hello everyone, does anyone know what is happening to this brass? This happened to me twice today at the range. I know the brass is a little old, but this is the third load using this Federal brass. The bullet never made to a 1000yd and fell short of the target about 50 yds. Weird looking...

    Variation in headspace

    Thanks for the responses. I use Imperial wax with my expand mandrel and while neck turning. It seems to work well. I own the K and M shooting neck turning tools. Great equipment, owner is not only helpful but knowledgable. He recommended I get the window riser to help during the...

    Variation in headspace

    After checking carefully, I believe I found that the process of expanding the brass through the expand mandrel can cause my shoulder to be bumped 2-3 thousands in headspace measurement. My expand mandrel has a stop at the base, which I may have hit if I am was not careful. The manufacturer...

    Variation in headspace

    Thanks Turbo54, My concern was that I gerenerated heat while neck turning and may have pushed just enough to lose a few more thousands. I believe I am taking the right steps to minimize heat, I am still figuring this out and appreciate the feedback. Which 7mm brass has worked best for you? RG

    Variation in headspace

    New to the board, need some help. I have taken several measurements in headspace and seem to have a variation of 3/1000 from fired to sized. However, after neck turning and case trim, I am off another 3-4 thousands. Does anyone know if the process of neck turning or case trim can affect...
