6-284 long range antelope load

[xring01]

I regret to say that I did not have the time to read this entire thread.

My 6/284 loves 49grs of R22 and a B105VLD. My best 4rd group is .087" @ 100yds. The load consistly shoots in the .teens if I do my part. Velocity is about 3200fps depending on the OAL to the lands.

Anyway, is not the fastest load, but it is very veery accurate.

Hey Kirby Allen I have this months Varmint hunter magazin in my hand.I tip my Hat to you! Congrats on 902 yards hit on a rock chuck.Wow!!! Hey whats the difference between a Rockchuck and a Priare Dog. Do they live side by side?What kind of hold over did you apply? What kind of scope? [img]images/icons/cool.gif[/img]

Iron worker,

Thanks, I had four qualifing shots for the 500 yard club, three with my 6mm-284 at 714, 715 and 774 yards but I felt the 902 with the 50 was the best for the 500 yard club.

Rockchucks live in smaller colonies of around 10 to 30 chucks compared to a P. Dog town that is often in the thousands of members.

They are also much larger. We shoot only the mature chucks and they will weigh in the 10 to 15 lb range comapred to 2 to 3 pounds for a P.Dog.

Generally the chucks colonies in this area are in rock formations generally no larger then 30-40 yards in size.

I do not have my drop chart with me right now as it is in the truck but I know that for a 900 yard shot, I hold on the top of the first mil-dot up from the main cross hair.

I am proud to say this was a in shot kill as well, I also admit there is a fair amount of luck involved as well but I will take that as well.

No doubt when the 50 finds its mark, also no problem spotting bullet impacts. The load I used was 225.0 gr H-50BMG under a coated 750 gr A-Max in BR prepped PMC cases and lit with a CCI-35 primer. This load produces 2720 fps from the LAR's 36" barrel.

I also have a 1000 yard qualifying shot on a chuck with another one shot kill with my 6mm-284 using the 107 gr Matchking but I did not build that rifle and will be going for the 1000, 1500 and 2000 yard club with the 338 Kahn I just finished building.

Kind of silly but I would prefer I do this with one of my own rifles, I suppose its good advertising at least!!

The scope on the 50 was a Burris 6-24x50mm Black Diamond with the Ballistic Mil-Dot reticle riding in Leupold MkIV rings.

Thanks for noticing!

Kirby Hey a while back I ask you about pressure signs.I mentioned that the last degree of rotation is where my bolt sticks.You said thats not a pressure sign,rather it might be a rough spot on the bolt where it "cams" Well I can't find a "rough spot" Compared it to my 300RUM[right at where the bolt connects to the body of the bolt][is that what you mean] and there was no difference.But the thing still sticks there.I back off seating depth by .030 today and all I notice was a 50 FPS drop in velocity.I don't think I know what I'm looking at our even in the right place.But if I'm not harming my rifle,than dose it matter?

I am guessing your b105 vld at 3200fps is a
Berger 105 vld,good choice in stopping at
49gr.RL22 mine blow's them at 50gr.RL22 at
3300fps. if this happen's to you switch to
sierra 107 mk's and live happy ever after

Iron worker,

The burr can be in two places that you will ba able to see easily.

The first is on the bolt extraction cam surface which is the angled section of the bolt handle where it attaches to the bolt body. You generally do not see it here all that much.

The other place is on teh reciever where this surface on teh bolt contacts teh reciever.

Other then that, it could be a burr on the bolt lug locking recesses.

It could also be that your cases are getting hard. How old is your brass. If it has been fired alot, it may need to be annealed. If the brass is loosing its elasticity then it will expand and stick in the chamber enough to cause harder extractions.

Check all of these out.

What velocities are you getting again?

Sometimes cases with alot of baring surface or cases with minimal taper can be a little sticky to extract. Also chambers that are not polished properly can cause the same problem.

Good SHooting!!!

Hey Kirby I'm getting 3,650 with the bullet touching the lands.Seating it .030 deeper gives me 3,600.It seems to shoot better with them touching the lands.Yes I'll check out what your saying.Thanks for your attention.
