O'Hara Maybe you need to go back to RL 15 ,105 Hybrids and a Dasher. Could hurt may even help LOL

Lol I thought those were just for making you look like you knew what you're doing! You mean I can actually use those ? Lol
Too hard to make good cases with consistent blow length , and I am at the end game .... jim
I just received from Billy Stevens my barrel chambered in 6mm Dasher. it is a Brux 7.83 twist/4-groove. I plan to shoot 1,clean for 4 shots, then 3-shots, clean for 2 cycles. Then I will try to tune with Re 15 and I have several bullets to try. I will try the method used by several short range shooters to find ideal seating depth. This method involves using two or three charges (from mild to hot) and several seating depths. When a seating depth will shoot in the same relative position on the target with all charges, one has found the ideal seating depth.
If you don't have a chrono, how do you know you go back to the same speed?
Most of my barrels want to shoot around the same velocity then I'll have one that doesn't. So I check the velocity but let the barrel tell me where it wants to shoot.
I believe that's what James is doing.

I'm just a flintstone with a couple of barrels and no chronograph. But assuming all the other components are the same, I just use the same seating depth you used before and start a .3 gr (depending on case capacity) per trial powder test, starting around a grain low, and obviously stopping at pressure. Fine tune from there. If I hit pressure early, retest and start lower.
So if I had a load before with 31 grains of powder, I would test 30.1, 30.4, 30.7, 31, 31.3, 31.6
The paper will tell you what it wants.

Alex: My recent purchase has your name on it. Would you mind telling me what “Dasher ST” means?

ST would be the initials of the person who designed the reamer. Thats how JGS labels them.

And here I thought you moved to Dasher St. Should have known better. That was an old address.

Mike you cheap SOB. buy a Chronograph looks like a lot of work to me! I don't think your going to be hard to beat this coming year, think your losing your MO Jo. Seen it coming the day you sat and waited. LOL

While breaking in the barrel, I noticed that with even 33.0 gr. of Re15 and 105 VLD bullets, there was vertical in my groups at 100 yards. It was about 40 degrees, and did not put up wind flags. Another thing I noticed was that the Re15 was VERY dirty. Even after one shot there was several coal black patches. Maybe this is caused by the anti-copper coated (supposedly) used by the makers of Re15. My next session, I will shoot three charges of Re15 (32.7, 33.0, and 33.3 gr.). With these charges, I will shoot at +.005 and then shorten the seating depth until I jump ~.020. The depth which shoots all three charges to the same relative position on the target will be my seating depth for further testing.

Rl15 was so nasty i abandoned it. It shoots good though

Probably not, since I'm still not buying a chronograph lol. Paper is cheap though.
I love when people say rl15 is dirty. You guys keep not using it. That was one of the reasons I didnt entertain it much at first, because that was the general consensus. But if you do start to use it, you'll find it shoots good, even when you're a little off. God forbid it requires you to use 2-3 more patches when cleaning. I dont care how dirty it gets, if it shoots, thats what Ill be using. rl26 is the same way in my 260ai.
Is rl-16 dirty like that too?
Seen it to Mississippi I like clean my barrel if I am winning !!!
