Vertical stringing

[Canhunter35]

I have been doing alot of dry fire practice and really fine tuning my npa with my hips and getting zero reticle bounce when dry firing. Also paying close attention to my follow through.

I am seeing the reticle come up and right (left handed shooter) a good about under recoil. I'd say 5 ft up and 5 ft right at 100 roughly. It's got a good brake and I can shoot it all day long but there's still some recoil being a 300 win with 215's


I took a video I'll try to upload it and see if anyone sees something I don't.

I read a good article someone shared on snipers hide on how to use your hand during firing, but I would say there's something in ur fundamentals that's not allowing you to control your recoil better.
Trying squeezing the most with ur pinkie and ring finger, you will notice if your squeeze with ur middle finger ur thumb will move,

Ok so I made it back out and shot 74.5 gr with h1000 and did a seating depth test with the wiser precision mount. Here's the results

.000" 5 shots- sd-20 es 48

.020" 4 shots sd 33 es 73

.040" 5 shots sd 4 es 11

.060 4 shots sd 10 es 22

.080 3 shots sd 14 es 27

I haven't measured the groups but they're all poor as you can tell. Those are 1" dots for reference. Notice how .040" had pretty good es and as and the group went horizontal and not as much vertical. My question to you guys is what would you do from here? Should I try .030" and .050"? These groups are making me want to abandoned the load all together but I'm not sure if that's the best move.

I was able to confirm the stringing is not velocity related.

I'd try .050 and see what happens. .040 and .060, groups didn't look to bad. Then try the three at 600 and 1000 yards.

I have a hard time with not seeing better performance at 100 yrds. These are probably 1.25" groups.

On a side note I was able to really get a better grip on the recoil management and my second sight pic was watching the hole appear on the target.

I start load testing at 600 yards. I don't care what it does at 100 yards!

If it doesn't shoot at 100 is it going to shoot at 6? I personally don't like contending with wind when doing development but maybe I should try to stretch it out

 

[C.O. Shooter]

In reverse as well. I've seen loads shoot bug holes at 100, but at 1000, it looks like the target was shot with buck shot!

 

[Canhunter35]

Regardless, joe is right, if he's hammering 1.25" at 100, 8-9" won't tell him anything else. The only benefit at 600 at this point is he will focus more on the reticle instead of the target and might shoot better groups because of that

Now that you have an improvement on vertical with seating depth try powder charge, primers, different powder. I'm no expert but I generally dial in a seating depth early on.

Went back out this weekend with imr7977 and was able to get a good load well under an inch for 5 shots. .7 with as of 9 and es of 21. Took it to 660 yards and shot this 5 shot group. If was super windy with a 10-20 mph wind while out. I'm pretty happy with it as it was so **** windy! I'll try again once I can get out with less wind

Stop painting my rocks! Darn kids!
Just noticed you're in my neck of the woods. If ya need a hand let me know. No expert, but I might be of assistance.
