Well Ami and went out looking for wolves and I shot the rifle to confirm drop. Input 2875 fps with all correct variables and program said 16.1 moa. 2 shots over the rock. Went 2920 and 15.5 and I was 5" high. 15.0 moa is dang close and that puts it at 2965 fps. Horizontal was dead on with 2" spread vertical I had 1 low 5" and scoped myself. What a ding bat! I was shooting off the mat and got in hurry LOL
Great posts!!! I have just soaked up 11 pages of talk.... Tells me I need to go buy some powder!!!! hahahhaha Retumbo is OUT at the local spot but the others are there so I plan on doing that... I just bought a LRH 111 off here from the guy that put it up and 10 minutes later I bought it!! hahahaah My lucky day.... I hope to get the gun in a few weeks so I will try all that you have posted and walk in your footsteps!!!! I hope to tell you what I see and shoot!!!!
Keep up the info and the results... I love not having to reinvent the wheel!!!!!!
Barrel life/throat erosion is a function of powder volume and cartridge dimension, commonly refered to as "overbore" a good example of overbore would be the fatter 6.5x284 compared to the 260 Remington. The fat hot steam of ten additional grains of powder coming out of the small 6.5 hole in the 6.5x284 generates lot more heat in the throat then the 260. Increased velocity is just a by product which is what you want in the first place. My 270WSM burned out a lot faster then my 6.5x284. My 300 WBY was gone in 500 rounds Fact is just about most of the magnums have comparable barrel life to the 6.5x284, some a lot worse. It's reputation as a barrel burner was earned by the target shooters that run very hot and are used to the smaller cartridges. They keep using it because it has super ballistics and accuracy. Shorter barrel life, comes with the ability to get the ballistics you need to kill game at 1000 yards with very low recoil. If you run a 6.5x284 at 2800-2850 FPS might as well shoot a 260. The issue is you trade off max range and ballistic performance. At 2975, the sweet spot for the 6.5x284, depending on the barrel, how hot you shoot it, cleaning process etc. You can expect 800-1200 rounds before you experience a drop off in accuracy. I'll take that any day for the ability to flatten a deer at 1000 yards.
Very sorry to hear about your dad. My dad is still with me but I don't know for how long. Worry about him a lot. I worry to much about everyone. Gonna worry myself into the grave if I don't stop, but I can't.
Rained too much this morning and then work got in the way so my 200 yard site in will have to wait til later this weekend.
I've got to do a lot of hunting with my dad over the years but not near as much as I'd like to. Hope to get several more seasons. And hope I live to hunt many seasons with my boy who's 9 months now. Off to bed now. Early morning
Thanks ShootnMathews, I lost my dad long before i got to really know him. Still bothers me today. Hard growing up without a dad. Enjoy every minute you can with yours as life is sometimes cut short. We tend to to take things for granted and then find out we're in a world of reality unexpectedly. Take care of your son and stay as close to him as he allows you. Not enough of that in our world today as i see it. Told you about the rain,same luck here. Wasn't for bad luck i wouldn't have any luck at all. Shoot Bug Holes .............SEMPER FI!
Well I sighted my 6.5 in today at 200 yards then checked the speed. I couldn't believe it so I plugged it into my bal. prog. Then dialed and shot the 500 yard target to check it. Hit where I was aiming so it must be right. 2591 fps. I really expected more. I'm now in a desperate search to find some Retumbo powder. I'm not a speed freak grasping for 3000+ fps but I do want to get at least 2850 or preferably 2900.
If anyone knows where I can order a pound of Retumbo please let me know.
Tomorrow I'm going to load some test rounds one each working up from 50.6 to see what I can push before creating too much pressure.
Any help I can get here to get my speed up over 2800, I'm open to safe suggestions. My current load is 50.2 grains of H 4831SC set .08 off the lans in lapua brass with a 210M primer.
Thanks for any help in advance.

I am a little surprised it is that low. How many rounds do you have through it now? With 4831 I saw 2900 at 4100 feet and 20 degrees. I am wondering if you have a tight barrel. Also hv1000 might be a good choice if you can't find Retumbo.
Btw my 4831 load is 54 g for Berger vld target. 53 Berger hunting. 140 grain. The targets have less bearing surface and can handle more powder and speed. My vld hunting have .040 more surface area. ? Sometimes this stuff makes my head hurt. Ha ha
