    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    Wow, that's detailed info! Thank-you! I have only been able to test 2 powders, as they were the only 2 that I could ensure I could buy more of if they worked. They are Accurate 4350 and IMR 4350. Since I bought them, the Accurate 4350 has become no longer available anywhere here in Canada...

    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    Everyone agrees on at least one thing: You gotta know how to observe, read, and react properly to what the wind is doing. THAT's another whole challenge I have yet to address. Right now, I am familiarizing myself with a Kestrel, but that of course is not enough. Jim G

    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    Yes, that's likely true, as I was never before that interested in long range shooting simply because I had no access to a range of sufficient length. Now I do. I have 300 yards 18 minutes from home, and 1000 yards 2 hours from home. The 2 hours each way for the 1000 yards is not great, but the...

    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    I know that there is disagreement about FL sizing versus neck sizing, and that some excellent champion shooters say to do full length sizing. BUT, those shooters are using custom-made dies and custom chambered rifles, made specifically to match each other. I have a production rifle and...

    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    The "sizing" I am doing for each cartridge is: Necksizing only to .291" OD NO body sizing required yet NO shoulder bump required yet - only 1 previous firing on the cartridges reloaded to date. Note that the case base-to-datum gew only .003" after that first firing, to 1.5365", which is still...

    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    The chamber IS tight. The rifle has only 200 rounds fired since new. No carbon ring (as would be expected with only 2 firings on the "oldest" cases). The brass thickness new was .0145" and within the attainable accuracy of a Mitutoyo digital caliper, it has not changed. Chamber is cleaned...

    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    Yes, taking that measurement is an "acquired skill". Hornady warns you about that in their instructions! Why not resized? Because: 1. I had only 2 types of Lapua 6.5CM cases: brand new and once fired, and brand new is NORMALLY way too different from a fired case fired in your specific rifle, to...

    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    Thank-you, High Desert Duck. You have provided a good perspective, and the reminder on the muzzle brake affecting the performance of the rifling is timely, as my thread protector has finally been delivered, and the additional recoil will surely have some effect on my F-Class shooting AND my load...

    Thank-you, 6.5SH. Those are helpful. I will check them out. Jim G

    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    That was uncalled for. I shoot 0.6" groups at 25 yards with my SIG pistol. And 0.2 and 0.3" groups at 100 yards with the rifle show that I do have some basic skills. I asked a simple, limited scope question about shooting from a bench. If you can't provide any help, why are you posting? Jim G

    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    High Desert Duck: Thanks-you. I knwo you are ocrrect about "never being ready", and plan to "get ready" by participating! The muzzle brake is removable - it threads off and I have a thread protector that replaces it! (I did check the F-Class rules) :) What I think many of the above posters did...

    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    If you "already know", why did you tell me that a 1 MOA load is "already good enough" when it clearly is NOT given a 1 MOA 10-ring? And if you "already know", you nevertheless apparently did not even know that F-Class shooters can use either a rest or a bipod. I asked specifically for...

    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    Maybe a 1 MOA rifle is fine in PRS, but not F-Class. The 10 ring in F-Class is ONE MOA in diameter. The X-ring is 0.5 MOA. So, a 1 MOA rifle won't cut it. I am in Canada, and my rifle was built by PGW Defence Industries - the folks that are equipping many International armies with their sniper...

    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    Thanks, Oregun. I intend to use the Bench shooting ONLY for load development. I'm hoping to avoid annealing, as my cases don't seem to grow much with each firing (tight chamber and moderate loads - only 2700 fps with 120g bullet), and my F-Class buddy, who does have rifles that need case...

    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    I agree that a fully specialized F-Class rifle might not be suitable for PRS, but I don't have a fully specialized F-Class rifle. Attached is a photo of my rifle. Note the Harris bipod. I also have the Rempel bipod for F-Class that mounts on the Picatinny rail visible in the photo rearward of...

    Now THIS (see photo) qualifies as a shooting stool suitable for benchrest testing of loads: - Solid, smooth, no-give thick, heavy wooden seat - Seat even reinforced with metal frame to which the ret of the stool mounts (NOT just screwed into the bottom of the seat) - Huge adjustment range...

    Brass Plated Steel

    Nickel plate cases provide some corrosion protection in wet environments. However, they react a differently than brass when sized and since Nickel is harder than brass, they could notably increase wear on dies. I suspect that is why no one recommends them for reloading. Jim G

    Techniques & equipment for load testing F-Class & PRS loads on BENCH?

    I disagree about shooting load development with exactly the same gear and position as in F-Class. I think it is important to know how well the combination of rifle and ammunition can shoot with the human input minimized. That's the only way you can know if there is a defect (or perhaps an...

    This sounds important. What specific differences make the rifles for F-Class and PRS non-compatible? Jim G
