    Seekins HAVAK Precision Rifle

    My favorite is the metal aics. It feeds a bit smoother than the PMAG.

    Christensen Modern Precision Rifle

    Here is a video by Alex Wheeler displaying how the primary extraction should be measured on a 700 action or clone. As I stated earlier, it is important to remove the firing pin to get an accurate measurement.

    Christensen Modern Precision Rifle

    I've seen that video and although he does a decent job of explaining primary extraction, he didn't correctly measure it. He really needed to remove the firing pin, make sure the bolt lugs were fully engaged against the mating surface in the lug recess and rotate the bolt straight up to get a...

    For those wondering about the case weight and variance of ADG 6.5 PRC cases. It's 224 +/- .5 grains.

    Rifle Scopes So, what about Leupold Mark 5 ?

    I ordered a set through the mil program during the first week of December, and I just found out they shipped yesterday. Popular items I suppose.

    ADG 6.5PRC brass

    How much do the cases weigh and what is the weight variance?

    Flyer's

    I'd work seating depth. .010" on both sides of your current depth.

    Powder recommendations 73gn ELD Match

    H4895 works well with the 73 ELD-M for me.

    Flyer's

    If you can determine that the flyer is load related, not rifle related you can make adjustments to your load to pull it in. I've fixed random flyers several different ways. If it's 2 together and one kicked out, often times a +/- .010" seating depth adjustment pulls it in. If it's a four or...

    First OCW Test

    You are really hung up on something. Wow! I even agreed when you had the node at 44.3. And guess what you said the 42.5 to 43.7 is another node, I disagree that nodes are that large but I'll go with it on this instance. You drop your charge right in the middle of that range and you have your...

    First OCW Test

    If you actually understand and you use the percentages a lot, why are you arguing about their usefulness in predicting the nodes? Newberry will tell you the nodes are ~3% apart, which means the accuracy and scatter nodes are 1.5% apart. Again, it's a very basic OCW concept used to predict...

    First OCW Test

    You act like the percentages are something new. This is a basic concept from Newberry's OCW theory. I'm not making this stuff up. The percentages are used for prediction and they align with what's on the paper. Honestly, how consistent do you think his load would be at 43.6 - 43.7...

    First OCW Test

    You're still arguing a moot point. The predicted nodes are correct on the paper.

    First OCW Test

    I agree. The calculations agree. 43 and 44.3 are the nodes. I don't know what you're disputing.

    First OCW Test

    I don't doubt it. Im going by what I see on the target and applying Newberry's system.

    First OCW Test

    OCW nodes, accuracy or scatter are ~3% powder charge apart. Accuracy nodes alternate with scatter nodes. A scatter node is opposite of an accuracy node and it falls halfway between the accuracy nodes. When you find a node, accuracy or scatter, you can predict where the next node will appear...

    Rifle Scopes Leupy Mk 5, 7-35 Announced

    It's a 52mm. It's the same tube as the VX-6HD 4-24x52mm

    First OCW Test

    Look at the scatter node at 45 grains. All you have to do is multiply 45 x .985. The calculated high node OCW is 44.3 grains. Based on further calculation, Your low node will be 43 grains.

    Good powder I can use for a 223

    8208xbr is the stuff for me. 23.6 grains with a 77 Nosler CC in LC brass is the magic combination in my Seekins 223 Wylde barrel.

    Christensen Modern Precision Rifle

    The Christensen side baffle brake is extremely efficient. I have no problem spotting hits with this brake on a 300 WM. The tunable ports are a bonus. I shoot a Christensen Ridgeline with 215 Bergers and starting from the shooter side, I pulled the first and the fourth plug from the top of the...
