Partial vertical stringing

[PowellSixO]

If you're going for a mild load I would try under that 42gr load and see if that group gets any tighter. If not, play with the seating depth a little at 42.

This ^^^^^^^^^


Also, I wouldn't waste money on a bolt on muzzle break. Either get the muzzle threaded for a break and do it right, or leave it as is. Too many potential problems with a bolt on muzzle break.

I would load up 42.1 or 42.2 and do seating depth testing.

May I ask why you also stated try a load at 42.1 or 42.2 instead of just doing the seating depth testing on the 42grain load I already shot? Just curious.

your stringing seems to be powder or loading related .. but on a different topic

boyds laminate stocks are relatively soft material -- and even though they seem tight they still give . and screws will come loose

i recommend a pillar job on all boyds laminates ,and a action bedding while you are in there

i would like to try some of these , next time

The stock is pillar bedded and action bedded already.

Bobby Hart once told me ,if the shots string add more power??? My remedy is sent it out to 300 below , she does a good job ,quick turnaround, Sent seveal factory barrels out the stopped the stringing, Most factory barrel are not stress relieved properly

Good idea but this is not a factory barrel and has actually had great groups with factory ammo and one set of reloaded accubonds. I'm trying to load a lighter bullet at a low charge to get a lower recoil round for my wife since she will not be hunting white tails past 250 yards.

Ok here goes. I'm working up some loads on a savage 7mm08. It is freefloated and bedded in a Boyd's stock. I'm shooting off rear bag and front adjustable rest. I loaded 120 ballistic tips .040 off the lands. I am just shooting at 100 yards. I started my charge weights at 42 grains and then went up .3 grains every 5 rounds until I got to 43.2 grains. Purely shooting for groups, not doing ladder test or ocd test. I started with the lowest charge and went up. Here is where it gets weird. I shot 3 rounds of 42 grains and get a .6inch triangular group. I decide to not shoot the last two rounds and move on to 3 rounds of 42.3 grains. Again I get about a .6-.7 inch triangular group. I I then go to 42.6 grains. FYI I'm waiting 15 minutes per group of shooting and about 1-2 minutes between each shot. The 42.6 grain grouping was a vertical string 4 shot group with almost no left and right deviation but 2 inches vertical. Each shot was progressively lower than the next so I'm thinking maybe heat. So I let the barrel cool 20 minutes this time. I went and shot four of the 42.9 grain rounds and the same thing happened... it is pretty hot out so I'm wondering if the barrel is just getting hot and I should wait even longer? This is a savage magnum contour barrel so just a step up from a sporter in thickness. Thoughts?

Give these a go. Loaf then full tilt and recoil will still be mild. They will handle anything with hooves in North America to the distance you are talking. If they don't do what you are needing, we will buy them back.

There is not a lot of data on that target but I have always had the best luck in the middle of a node and it appears you have one around the charges I mentioned.
