load development

  1. Shot my first load development, results not great

    I am new to reloading for precision rifle. The rifle is a ruger precision rifle in 6.5CM. I watched a bunch of ultimate reloader's videos on load development and followed it to the best as I could and my numbers weren't that good. Is there something I'm not taking into consideration that can...

  2. Check me -- Load data for Superformance powder, in 6.5 Creedmoor

    Am considering doing up a load for a Savage 12 LRP in 6.5 Creedmoor, using the Hodgdon Superformance powder. But I've noticed that the Sierra 6th Ed. manual has a significantly higher max powder charge listed. No listings for the Nosler RDF bullet with Superformance, but here are the closest...

  3. Data gathering for barrel design theory

    Hello everyone, I am gathering data to try to explain a certain phenomena. Why do some rifles center of groups trend down or up as velocity increases. The goal of this thread will be to develop a calculator that reliably calculates barrel length and profile required to produce a flat or...

  4. Load development in winter vs summer?

    Just got a new rifle (bolt- 6.5 Grendel-22” Howa barrel) Worked up to a mid weight load (25.7gr of IMI 8208 XBR) with 130gr sierra game changer OAL is at mag length (2.310”). Manual says max load is 26.4gr. I’m going up in 0.2gr increments, showing zero signs of pressure thus far. Shooting temps...

  5. Burn rate vs barrel length

    I have a new 224V with a 30" Bartlein 5R bull barrel, progressive twist to 6.5, reamed for an SMK 90 grain, and I'm curious about burn rate vs barrel length. I've never tuned a load for such a long barrel. The gunsmith, Joe Carlos, developed a load for the rifle using N-140, but as I come up...

  6. Need a Good Target Design For Load Development

    I'm about to start load development for a hunting rifle and I'm not happy with the typical targets I use for sighting in. Is there a target design that does a particularly good job of helping center the crosshairs on exactly the same point? Or maybe I should ask it this way, what's your favorite...

  7. loading data does not match my rifle

    I have a Swiss made Mosin 7.62x54r that slugged at .312" all the loading date is for .308" bullet. The British 303 loading data is for a .312" bullet. Lets say both the 308 & 312 bullets weigh 180gr. Which of the two calibers loading data should I use?

  8. Burn Percentage

    im working a load with a .308WIN 116gr custom bullets (reserving the manufactures name for the time being). I don't have much data on the bullet so I'm going by best guess and the manufacture recommendation of 48gr of Varget @2.8" COAL. The closest match I can find is a 125gr or 110gr Berger, or...

  9. Load development sequence - Help

    Given that there are many variables that factor into an optimum load such as: Bullet manufacturer Bullet weight Powder type Powder weight Primer type Seating depth Can someone suggest a sequence to go about establishing the optimum load considering these variables. Which...
