We have 9 Dashers all shooting 36.6 gr of h4350 It might not work for you but it sure does for us
Seems to me you are the only that does this. I will not compress a powder due to the problems it can cause...... jim

The only problems I ever experienced compressing powder was that it shot much more consistently.
R15 and varget in the 223 and the 55 grain bullet for example. Basically as much powder as it will hold and seat the bullet. Immune to all conditions. Pain the butt to load bulk but man does it shoot.
I know. it shoots good .Seems to me you are the only that does this. I will not compress a powder due to the problems it can cause...... jim
View attachment 1075622 View attachment 1075623 View attachment 1075624 My 6BR barrel now has 2,400 rounds on it and still shot a 598 35x score at 600 yards 2 weeks ago. Look at the targets from my F class shoot shot with 34.6 grains of H4350, they show the SD at 13.8 and 17.4, a pretty stable load. I measured some leftover ammo from 2 weeks ago and the seating depth has not changed. I’m running .002 neck tension. Attached are some pictures of a 6BR case with 34.6 grains of H4350 right at the neck shoulder junction. This is not a compressed load. The brass has at least 10 firings on it and is doing fine. My drop tube is just under 6” long. It works well.
Jim,That maybe fine for F Class mid range SD of 1 or 2 would shoot smaller, in fact SD. doesn't enter the picture ES of single digits is what I seek. The records now at BR 600 are 5 shot groups in the .3 area 1" is quite common.....jim
Unever pressure on the bullet, hard to hold seating depth, hard to load and it doesn't shoot as consistent as non compressed loads. what your referring to is an AR? sub .1 loads aren't going to happen, if you had one it would not repeat..... jim
Jim,
I think those SD’s are measured at 600 yards by the electronic target system. With all the environmental variables effecting the bullets flight, I would think a SD of 15 out of a 20 shot string measured at 600 yards is pretty darn good.

Pssshhh... Whatever. No, it's not an "AR".
Great information.View attachment 1075487View attachment 1075488 View attachment 1075486 This load was primarily developed for F class. I do not shoot benchrest. Here are some targets. I do not have flags and I did not adjust hold for wind while shooting these groups.
Why yes it is 4 years old...Hmmmm a 4 year old thread. Probably a couple barrels since last post.

Find a fiberglass or carbon fiber arrow of the right diameter(most sport stores have an assortment of long arrow blanks), wrap electrical tape around on end until it makes a tight fit for your powder funnel, chamfer the other end so it fits over the mouth of your case. Build a simple stand to hold the drop tube vertical and your set.Now to find/make a drop tube. Thanks much.
