Official .260 tOBR Thread-Pics/Range/Loads/Updated Thread Index (Page 19 of 188)

OP-Keep practicing taking photo's through the scope. It's like lining your eye up with the scope but a tad more difficult :) While holding the phone with both hands use the volume button to take the photo rather than the on screen button.
Also it would be handy if in the OP you had "thread updates". With direct links to posts within the thread with info another Larue 260 shooter could use. Such as which ammo gives best groups, reloading data, tips & tricks. If it was all in the OP people who don't follow the thread could find the info easier. Just a suggestion. |

Maybe you can relate to my situation if any of you are homeowners. My wife and I have been bringing van loads of stuff to the Salvation Army for 15 years. Somehow, after we clean out the house for the umpteenth time, there's still more "stuff." I honestly think the stuff reproduces at night like rabbits. Same with my Battle Mixers, I kept finding them throughout the basement and garage, a few here and a few there. I gathered them up and I have a dozen that aren't being used and a couple more that were used. Are they following the script and reproducing? I have enough already! 
My Whidden bushing die arrived along with some of the neck tension bushings. A bushing die allows you to play with the neck tension of the cartridge so you have suitable bullet tension given how deep, or how long, some of these projectiles are seated. I hope to play a bit with it tomorrow and will report. As to reloading, I'm going to work up loads at 2 grain increments and at COAL, hopefully for shooting this Friday. I'll also give the imperial wax a try.

I need to play with the neck tension a bit and the only way to do it was to order multiple bushings at $15 each. |

I shot with it today for the 1st time. I noticed a 2 MOA shift down and had a 5-6 FTE's out of 60 rounds shooting suppressed. Anyone else notice these issue when installing the PRS? |

Some of you with kids who have left the nest will relate to this, but we still have animals they've abandoned, specifically two cats. I didn't know these damn things lived so long! All they do is eat, sleep and poop; they lack compassion and could care les about us, until we don't feed them. They also drag their conquests into the house if we're foolish enough to leave the screen door open. They'll play with the poor victim until it hides someplace and dies, leaving us to search for it once it starts to smell. I heard a potential victim squealing today and ran downstairs to find this poor vole being batted around. I was able to save it and get it to the backyard hill we have where it hangs out in a system of tunnels. I can't wait until these cats die off.
I loaded up some rounds today, hopefully for a local range trip on Friday. I broke out the Wilson case gauges and measured 50 pieces of Lapua brass. All were within COAL tolerances so I didn't trim any of these virgin pieces. 
The case gauge has two measurements, one side is case length and the other is headspace. You place the brass into the case gauge and then look at where it falls within the gauge's minimum and maximum shoulders. The Lapua was virgin so the headspace was all in specs. The case length varied a bit, but all were within a ten thousandth. Because these were in specs, I did not trim them. I also checked the case mouth and no chamfering/deburring was needed. 
Out of 50 virgin Lapuas, there was only one where the case mouth was flattened: 
Then it was time to prime the cases, which I do using the Forster Co-Ax press, which has a priming area on the top of the press. You simply center a case using the primer tool and then set the case holders. Then you install the correct primer pocket tool and you use the stroke of the press arm to prime a case. The Forster automatically sets the primer and seats it under the case head so it's properly resessed. 
I decided to crack open my stash of Federal 210Ms to use for this load development. 
After a few minutes I had 50 primed cases. 
I decided to load the Hornady 130 ELD-Ms so it was off to the Hornady manual to see the specs and load data for the .260. 
Oh, oh, no 130 ELD-M load data for H4350. Off to the website to pull an update: 
I'm going to do a 10-shot ladder test so I decided to load in 2gr increments between the minimum and maximum. I loaded 40.8, 41, 41.2, 41.4, 41.6, 41.8, 42, 42.2, 42.4 and 42.6grs of H4350. Why I loaded so many across such a spread will become clear in a bit. I used the RCBS Chargemaster to drop the powder. 
50 rounds charged and checked: 
Now it's time to seat the bullets. I'm using Whidden dies and the seater has a micrometer that allows you to dial in a very specific depth pretty easily. COAL is 2.800, but I loaded to 2.730. 
All done and ready for the range: 
So, why did I load 50 rounds across such a spread? Easy answer I wanted to maximize my range time on Friday and hopefully narrow down a good load in one trip. Now, I'm using a 10 round load development concept that I read over at 6.5 guys and that had origins in Creighton Audette's testing. I'm going to shoot one of each load and chronograph each to find the spot where there is minimal deviation in the speed. That point, for example where 4-8grs makes minimal speed impact is where I want to be as it's a SD sweet spot. After all, it's not about how good a 100 yard group you shoot, but how low a standard deviation you can have, which translates better at long range. Once I find that velocity sweet spot, I'm going to fire the rounds in that grain range to gauge accuracy, From there I can tweak a bit and work COAL. You can read more about the ladder test as follows. Any rounds that don't work will just be pulled and re-loaded. 6.5 Guys 10rd Load Development Audette's Ladder |

You've probably seen this, but if not: What the Pros Use I have used both of the optics you mentioned, as well as the SB. I just come back to what will I be happy with. And I even thought about the Nightforce as well. Its just that the SB has a mag range that is awesome, a lower low and a higher high end, both which are functional. Most of the others I have used the clarity degrades at those extreme mag levels, low or high. |

Look at the Dillon 550 since you are here in AZ. With a whidden tool head they are really good, make concentric ammo. They have a model without all the bells that is much less. |

Glad I have most of the reloading gear I "need" already, only need to pick a die set for the 260 and bullets , have a rock chucker, a pacific single stage and a old texan loadmaster turret press on the bench (along with a dillon SDB 45acp and getting ready to order a XL650 for my 9/40/223 3 gun ammo)
This scope talk is also relevant to my interest =) need to pick whats going on my 260 as well, I'm current considering a Sig Tango6 5-30x56 w/ DEV-L MRAD reticle. Looks pretty good and street price is about the same as the Gen2 HD... |
