I enjoy the research prior to buying any of the reloading components. We are blessed to life in a day and age where knowledgeable people, like yourself, share their experiences. Components are expensive and if you can start closer to the final solution based on the research, you can shoot more enjoyable groups. Thanks for sharing.
The 153.5's already have Bergers Meplat Reduction technology and a G7 of .356 I'm running them in a 26" 1:7.5" Bartlein , 2,745 with about 200 rounds on the barrel.
Great video. I’ve been having great results with the 140 for a long time. I hadn’t thought much about trying the heavy Bergers in anything other than a 6.5 PRC. Based on your info I’ll give the 153.5’s a shot.
Also, just to note, not all electronic targets have a target velocity. It depends on the design of the target. Hollow acoustic targets don't provide and speed data. Radar targets do. I shoot in Canberra Australia, there is a guy here that used to build electronic targets, when he starts speaking about target design, whoa that is some deep engineering lol. I think he said his son worked on the gravity wave detector.
Keith I use the 156 in my 6.5 x.284 hunting rifle, 8 twist no problem. I’m at 2890 - 2915 fps . I haven’t yet tried them in my f class 6.5 x.284 but plan on it with the long barrel. My Creedmoor likes n-150
156 is a good bullet, but I don't know any top level shooters using the 156's if they can get the 153.5s. As far as that goes, there are very few top level shooters in the PRS using 6.5's. The 6 Dasher is by the most utilized cartridge in the PRS, especially among the top shooters, and for very good reasons. Regardless, if you're looking to go the 6.5 route, then the LRHT 153.5 is the candidate you should be testing since it's already pointed AND has a higher and more consistent BC...and how to reduce those SD's. ;)
Good choice. I am shooting this in competition. However, I have slightly faster twist than you. But still it's the closest thing there is to Hybrids in terms of performance and consistency.
Realistically each chamber should only have a small window of bullets available. Say if you shoot 7mm from about 130gr to 160gr will be a standard length freebore in most cartridge stock chamber offerings. Now step up to 168gr and you will need more freebore, and you might be able to shoot 180gr. I just ordered a reamer for 7mm-08 AI and had the freebore set to .240" so it will shoot 180gr seated in front of the neck shoulder junction, if I want to shoot 195gr projectiles, well the boat tail ends up .100" past the shoulder case junction, doable but not ideal. So realistically you would want a barrel for 168/170's another for 180/184's and another for 190/195's all with the appropriate freebore to allow for some jump but still be out of the donut area of the neck.
I never could get the 156 bullets to shoot nearly as good as the 140 berger hybrids in my 6.5 creedmoors.. they did ok being pushed hard in my 6.5prc.. but for me I found the berger hybrid 153.5 shoots alot better in the 6.5 prc.. I stuck with the 140 hybrids in the 6 5 creedmoor
Why do you not shoot with a silencer? Do you find that it makes the barrel inaccurate or do you live somewhere that they don’t allow it? I find when I shoot my guns with a silencer it makes it shoot better. Perhaps because it strips the turbulent gasses away from the projectile.
It’s too much trouble dealing with the legalities. I choose to just stay away from them for now. If it were an over-the-counter thing without special tax stamps, etc., I would love to give them a try.
I enjoy watching your videos even though I don't shoot competition. As I pick up little snippets of info that I use in my reloading. I noticed tour bolts is fluted, what is YOUR reason for doing it please? I spoke to one of the gunsmiths I use, and he suggested I jewel mine and not flute it! Sorry for this silly question, you have talked about pointing your bullets! When doing that, are you compressing the point to another shape or trimming metal off it? Thank you for sharing your wealth of knowledge with us.
I'm curious to see what bullet you land on in the 6.5 Creedmoor, what powder you use and what the velocity ES and SD are for your match load. I've been playing with my first true precision 6.5 Creedmoor (after several Tikkas and semi autos) and haven't been any to settle on anything. The barrel is just barely fully broken in, but I've yet to really see clear evidence of what bullet I'm going to use. In part that's a good thing because everything has shot fairly well, but I need to commit to something and purchase a few 500rd boxes (or 3k round cases) here soon
Higher BC is OK. But what is the heaver bullets lower velocity and higher BC have effect on time? I never see anybody talk about this. Say my 30-06 Shots 1 MOA at 600yds. The Sierra 200g leave at 2800fps. 230g Sierra leave at 2630fps. Its takes the 200 to get to 600yds in .733 of a second. To get to 1200yds it takes 1.701 seconds. Or .968 of a second to cover the last 600yds with the 200. So you divide .968 by .733 = 1.32. Multiply the 600 yrd 1 MOA group by 1.32 and you have a group size at 1200yds of 1.32MOA. The 230s Take .772 of a second to get to 600 and 1.765 to get to 1200 Doing the math says a 1 MOA Group at 600 becomes 1.28 MOA at 1200. But it is spending 3.5% more time in the wind. NDR
Just curious, how do you get a 7.83 twist barrel. I get that you custom order one or multiple, but how did you end up at 7.83 twist instead of 7.5 or 8.83?

Thanks, enjoy the scientific side of your videos.

I do enjoy your content

Hi Keith, are you still starting your load development with .010 in lands for vlds, .005 off for tangent and .015 off for hybrids?
My process hasn't changed from what I disclosed in previous videos.
What you think about the 6.5x47L for heavies like 156's compared to the 6.5 creed?
Higher BC is OK. But what is the heaver bullets lower velocity and higher BC have effect on time? I never see anybody talk about this.

Barrels are custom ordered from the barrel maker.
interested in what is sitting on the shelf that you can’t utilize.
Sorry I’m a newb- another question, do you actually work the tips of the ammo to make them more pointy? If so, how?
I believe there is a pointing vide.
What brand of adjustable butt pad do you use on your F class stocks
Go back through his log. He has some great tips.
Thanks for the good video.
Whichever video it was on, it's pronounced "MAY-plah" according to a hornady catalog.
