But hopefully I can find some good bits of data that will be useful to you. I wouldn’t argue with someone who has measured results different from my own. Just a note: Some of the Powder and Bullet company links don't go directly to the 6.5 Grendal data, so you have to do some searching. None of this is anything that you can't find yourself, but I hope it will save some you some time. Your elevation, temperature and barometric pressure will vary from my testing conditions as well. I've assembled a bunch of links to 6.5 Grendal load data from across the web. I plan to run my tests through several barrels of each length, but whichever barrel you have might perform a little bit differently. 2927 Notes: maximum load compressed powder charge COL: 2240 49,400 psi 85 Sierra HP IMR-4198 Subscribe to 2645. The same document also indicates a 120gr load using Alliant Power Pro 2000-MR at. ETA: Finally found some published load data for AR-Comp in a Grendel and it indicates that 25.3gr is a maximum charge for a 120gr bullet, so my load above is a greater than max load. Just as a quick note, none of this is meant to be definitive. The load is 123gr SMK HPBT, 27.5gr AR-Comp, CCI 450, Hornady brass, 2.260' COAL. Federal Gold Medal Berger 130 grain OTM.Federal American Eagle 90 grain TNT JHP.Wolf Military Classic (Steel) 100 grain FMJ.The ammunition I’m using is listed below. The barrels I’m using are 16″, 18″, 20″ and 22″ Liberty barrels made by Satern in Iowa. I’m not sure if this has ever been done before, but I haven’t seen anything quite like it. Measure velocities, calculate energy and trajectories and then post the results for you to reference. What I’ve decided to do is take the four most common lengths of 6.5 Grendel barrels and shoot through them the eight most common and readily available factory loads on the market to see how they perform. Intended use will be hunting, deer and hogs.The Plan. Since Ill have a CZ I realized this would probably be the better place to ask What is a good all-around load for this cartridge, for use in the shorter barreled rifle I am buying? I found that none of my manuals have data for this cartridge, and as I said online data is somewhat difficult to sort through. So Ill be buying new powder, new bullets, new dies (ordered already) and new brass. I have 6.5 bullets but they are all 140s which generally appears to be considered a bit heavy for this cartridge. However, the 6.8mm SPC and 6.5mm Grendel, need a new series of links been. I was surprised to find that dies were rather expensive, and that none (zero) of the many powders I have on hand appear to be recommended for use in this chambering. If the rifleman's basic load of ammo is kept at a constant weight, the box. somewhat confusing, maybe due to much of it being for AR type rifles. I have hand-loaded for over thirty years, but have no experience with this cartridge, and online data is. It is the synthetic stock model that has the shorter barrel which is suppressor ready.
