6 dasher problems

[hoene72]

Hi I am having a hard time getting my dasher to shot. It is a savage target action,brux 1-8 twist,on a sharpshooter supply dog tracker stock. Have tried reloader 15 and varget using 100,105 bergers and 107 sierra bullets. Not having any luck. Any idea what I should try next.

Did ya get the case in the chamber, can you pull the trigger, can you hit the target??

My point, while it may appear to sound sarcastic, its not meant that way.

The point is we need more info, whats it doing, not doing?, etc.. Load data, etc...

Using CCI450 primers,Varget started at 31 grains went up to 33.5,and the same with reloader15 with all bullets set so the bullet is pushed back in to case when closing the bolt. Loaded 3 shells in half grain increments and shot them. The best group was with 32.5 grs of varget. The group was around a 1/2 to 3/4 in group at a 100 yds.

Dont own a Dasher but do have three BRX's and a BR, they all shoot the 107 better jumped somewhere between .020 and .040, I take special care to assure consistent neck tension, I run .001-.0015 of bullet grip and anneal after fire forming and every three or four firings thereafter, are you full length resizing?

Pull your bullets back, try 0.020" 0.040" 0.060" & 0.080" off the lands

whats your bedding situation, i had forgot what you had told me. Did you re-bed that stock? How much torque are you putting on the action? I have a feeling it is a bedding issue more than anything else. It is also quite possible you have a lemon barrel. it doesnt happen often but it does happen. Also you said something about it shooting well with 95gr bullets. whats the story there? We will get it figured out when we go to the range. Lets talk about it a bit here though. maybe we are missing something? Lee

I spent 600 rds trying to force my dasher to eat bullets it didnt like. 4 powders , 3 primers seated from .140 out to .025 in and every place in between 4 different bushing sizes. Then I tried some Bibs and it was like flipping a switch. What im saying is dont waste a lot of time and barrel like I did, be willing to change.

Try H4895, 32 grs. with the Sierra 107

 

[skeetlee]

If an 8 twist dasher won't shoot re15 or varget with a 105 to 108gr bullet it isn't worth having.. something is wrong with my buddies rifle or barrel and I don't really think it is the bullets or powder he has tried. I have been wrong before though. We will get something figured out. Lee

Started with bullet jamed,also tried seating the bullets off. Went in 10 thousands at a time. I bedded the rifle with devcon gun didn't shoot so took dremel to it and took it back out. Thought there might have been something wrong with the bedding job. Scared to try it again almost stuck the action in the stock.

I had the exact same problem ith my savage brx that SSS built, but i spent ove 1000 rounds to try to figure it out with no luck. the best it ever shot was one group at 5/16". sent it to nat lambeth and he re-did it all and it shoots everything now. the worst its done now is 1/2"

Dashers in my experience are kind of like peeky two strokes. No two are alike and need to be loaded/tuned correctly. I own several and all shoot different loads with different results. I have two 22Dashers that have .022" difference between the base to datum. Obviously they like different loads. I have noticed that small things like neck tension, powder charge and bullet seating can change velocity spread greatly. When I stumble upon a load that shoots I keep some as a control. I then test as I don't shoot competition so I'm always testing. If I get a load that shoots all over the map I go back to my known good load to see if it is the load or me or something like a clean barrel or a dirty barrel. Try eliminating variables from the equation; like assemble all the test loads with finger tight neck tension. Weigh every load with an accurate scale and weigh it twice.
Check all the volumes of all the rounds you have and segregate them by volume. Then segregrate them again by velocity. Start jammed and load every load just like that until you find the most accurate, seek the most velocity with the most accuracy. I have one that wants 2888fps and nothing more with 108 Bergers.

I'll chime in for 2 cents worth. I am not sure if your rifle ever shot or let go. If Varget, Rl 15 and H4895 won't shoot groups, I mean is it throwing one out? Then I would be very suspect of bedding. The bedding is often more important than people realize and Dan D told me he has seen several accuracy issues with bedding. Another is a Dasher downfall (short neck). Same issue with 6.5-284's. Often new barrels will create the carbon ring which can be a bear to get out! in a newer barrel it can form faster than an old one. They are also picky on bullets but I have never met someone who couldn't get a Berger to shoot lightly jammed. Sierra's and Hornady's can sometimes be tought to make shoot o.k. Dashers also seem to like FL re-sizing and very often the head space will be off depending on the reamer/die combo. Remember to pull your firing pin and check your shoulder bump and base re-size. This will contribute headaches also. Don't be afraid to take .0020 of your shell holder if need be. Keep us posted.

... Don't be afraid to take .0020 of your shell holder if need be...

Funny you brought that up... I had to do that, but went about .003"

Hi Again
Well went to the range and tried again. This time I removed the middle action screw and torqued the others to 50in pounds. The 3 loads i tried where cci 450, varget 32.5 grains. The first was 107 sierra vertical 1.280, hor .953 then berger 105 vld ver 1.013 and hor .952 the last was bibs 107 ver .690 hor was 1.660 . Fired all at 200 yards cleaned barrel and fired 2 fouling shots before each group. All bullets in the rifling. What do you guys think the best group would be to work on and what should i try first. These are some of the best groups fired.
Thanks

And the velocity spread is? And the neck tension is? And the barrel length is? Do you use quick load and the OBT tool? I'm trying to help but if there are too many variables it is hard to get anywhere. Measure the length of the barrel from the muzzle end with a cleaning rod with the bolt closed. That will be your barrel length. Next weigh your cartridges with the spent primers in. Now fill them with water and weigh them again. Subtract the dry weight from the wet weight and that is the grains of water. Post back here and I'll calc it in quickload. I should get pretty close as I have Quicload set up for Dashers and I get fair predictions. Measure your twist and make sure it isn't 9 or 10 if it is 10 it will shoot the 75VMax like a laser if it is eight it won't. Didn't you say that it shot 95s better?

Hi
Neck tension is.002, the barrel is a 1-8 checked with cleaning rod. Empty case weight was 129.2 full of water is 170.6 . As far as the 95 grain bullets they shot the same as the heavier bullets. Going to put it on a differant action and stock.

Impressive offers and information to help. Wonderful.

Paying attention because I gave up after 500 rounds with my Dasher. Been waiting months for another barrel from Krieger. My old McGowan had me give up. Tried most all of the ideas I see here but not all.

Darn you guys are good.

 

[dogdude]

My DASHER (krieger 8 twist) loved sierra 107's, 30 off with VARGET but it would not shoot light's out till I was going way to fast. the brass took a serious beating,but I had to do it. I don't recommend it to anyone else. switched to 6x47 to get a little faster fps with out tearing up the brass. good luck with your DASHER and please take your time and work up SLOWLY all best dogdude

I have never seen a Dasher that didn't like 33.2 grains of RE15 and as you have gone all the way to 33.5 in your gun I would start there.
I would also stick with the CCI 450 primers for right now.
First thing I would do is clean the barrel thoroughly meaning it will take you several hours.Put plenty of whatever cleaning fluid you use in it hit it with several passes of a bronze brush and let it soak for an hour.Repeat this as often as possible for the better part of a day and then run some dry patches through it.
With the erratic velocities you are getting I suspect you are pushing the shoulders back way too far.If you can? neck size your brass only.
With the spent primers out of your cases measure from the casehead to the shoulder and if you don't have the right tools improvise by using a larger case.I will try and post you several pictures.
You want to use the longest brass you have that fits your chamber as the shorter cases will scrub away too much velocity.
Load up 30 rounds at 33.2 all to the full jam length then set groups of 3 rounds back 0.005 at a time measuring at the bullets ogive.You need to seat each bullet seperately one at a time no matter what press and dies you use.
Report back what you find out.

P.S. I can't figure out how to post pictures here yet as they are all too big
