Savage 111 LRH 6.5-284 Loading Questions

[BrentM]

You are certainly free to do what you wish but fliers can be from a large number of factors. A lot of times from powder charge. IMO I would do 3 at .075, .100 , .125. I load in the field and 2 at a time. If I get a tight pair I load up 2 more. That's just me though.

I totally agree. There is a lot of factors that could cause flyers. But the flyer was low. At 6 o'clock when seated close to t he lands, <.025". The only thing I changed was the seating depth to .050" and he flyer moved from 6 o'clock to 12. I shot multiple groups of both with i dentical results. That makes me think that is a seating depth issue. Here is the last two groups I shot. Flyer at 12 o'clock incase this picture posts sideways. The group with overlapping holes is 50.5 grains and the one wih two side by side is 50.2 grains.

For today I loaded a group the same length as in The pic but at 49.9 grains. To see if it will pull the flyer in. I also loaded a group at 50.2 grains and with .040" jump instead of .050". Hopefully one of these loads will pull those flyers in. If they do not then it could just be a problem with the tension on this accustock. I think I will be replacing the stock before long. It just adds another factor into the mess of tuning.

I set my stocks to 45 inch lbs. I have 2 identical rifles and have pulled them apart several times with no issue getting same accuracy. I am not sold on the accustock one way or another but both my rifles shot .3 or better consistently with a tuned load.

FYI- I had a flyer issue at .075 off the lands with my bergers and 57.5 grains retumbo which netted 2975 fps. Usually a 12 oclock flyer like yours. I increased the jump and reduced the load to 56.5 at .100 and the rifle settled in at .25 MOA at 2940 FPS.

The only other thing you might try, to rule out the shooter being excited about shooting a tight group, is to shoot 4 instead of 3.

Also, remember that increasing and decreasing the depth does change the pressure in the case and not just increase it by a number but also via a spike. I see more spikes in pressure closer to the lands then I do with more jump. In fact I often reduce powder charge when seating to the lands and still get pretty high velocity. You probably already know all this but it is easy to forget.

I'm not sure what the poundage is on the stock now. I think 40 lb but I'm not for sure. Ill check it tonight and set it to 45. If it worked for yours then maybe mine too.

I'm sure it's not a shooter issue. I burn a lot of powder a year doing long range shooting. I'm confident I'm not pulling the flyer.

If these next two loads don't group up then I might jump back to .07 jump or so. My buddies 300wm likes a long jump. He gets flyers when set anywhere less than .05" to lands. I just have so much bullet in the case now that I want it as long as possible. With the berger 140s I had less than an 1/8 th inch in The brass. These are totally opposite. It's like the whole bullet is in the case. I bet the boat tail of these is down past the shoulder.

I noticed last night that the flyer in the 50.2 grain load was lower than the flyer in the 50.5 grain group. So I loaded one group at 49.9 grain. I shot it a few minutes ago. Very satisfied with it. Two side by side touching with the 3rd stacked neatly on top forming a nice clover leaf. Ill shoot the group with less jump also to see what it does before loading more of these

( picture will most likely rotate 90 degrees left)

Here is the other group. It is more horizontal than the last. Ill load another group of these and try them again.

 

[ShootnMathews]

Loaded another group like the last. 0.90" at 250 yards. I figure that to be .344 Moa. So it's doing much better now.


Ouch. Just ran numbers thru shooter. It calculates 2650 fps. That sucks.

Did you zero and then shoot drop? Seems pretty low

I zeroed it. Then measured drop at 250. But it might be right. The Nosler has AT LEAST twice the bearing surface as the Berger. Maybe more. And I was shooting g 52.7 grns with the Berger. 50.2 with this Nosler.

Your velocity seems right to me with that load

 

[ShootnMathews]

I will say my velocity with this load is depressing. My drop with the Berger was 13 Moa at 800. Will be 23 Moa with this load. I needed something consistent and packable for hunting season. As soon as I get this tuned a little better so I know I can hit my game out to 509-600 yards, I going to start load work with the bergers again. I'm going to seat them plenty deep enough for holding concentricity and do another ladder test. Start from scratch again. Try to get them where I can trust them. I hate to lose those those ballistics.

Broke in new barrel. 2 different loads shoot well. Here is my favorite. Drop at 500 shows to be 3050.

That's a nice group Brent!!!

Thank you. Here it is mostly done. Art work on muzzle and chamber
