6-284 long range antelope load

Fiftydriver · #43 08-19-2004, 07:03 PM

Brian B,

My rifle is fitted with a 30", 1-8" Lilja barrel.

The load I was using was 57.0 gr Rl-22 in Prepped Win cases.

I have a very tight neck in my chamber, .266". I alos have a long throat in my chamber to allow the 107 gr Mk to be seated very long for the 6mm-284.

On top of that I coat my bullets which I have tested to increase top velocities but an average of 50-70 fps.

On top of that my barrel has a 3 groove rifling design which I have also found to allow 50 fps or so more velocity from a perticualr load over a conventional 6 groove design.

That load was averaging 3599 fps for a 15 shot string with an E.S. of 12 fps and it was shooting 3/4" three shot groups at 500 yards!!

This is a very hot load and brass was letting loose after 4 firings so I downed the load to 55.0 gr Rl-22 which produced an acverage velocity of 3510 fps with very similiar e.s. and group size.

May be a fast barrel but thats what its doing. The 6mm-06 I just built for a customer is getting the 105 gr A-Max bullets to 3600 fps from a 28.5" barrel. Shooting in the 3's as well at 100 yards.

That rifle has a 1-9 twist though.

My Lilja 1-8 will top out at 3200-3250 with the Berger and Hornady 105 gr pills. This is also the reason I had to go with the 107 gr Mk.

Good Shooting!!!

Ok I thought seating the bullet out to rifling lands increases presure thus more velocity,That is what is presented in the drawings in the begining of a Hornady reloading manual when seating the billet is talk about..... .I was excited about 3,650 with the H4350 and Hornady 87 V-MAX.Hey just yesterday I drilled some sguirrles,Man that load blew them up big time,I mean were talking body parts 30 feet away from impact.That is when they were oh 75 to 100yds away.

Iron Worker the pressure will go up when you seat the bullet into the lands but not the FPS. The reason is you cannot get the same amount of powder in the case as you would be able to with it off the lands a little bit. That is why Weatherbys are Free Bored. Try it for yourself take your load back the bullet off 30 thousands and see how much more powder you can get in the case to achive the same pressure and see if the FPS goes up.

Dakor I'll try it,hey what is your scope? I'm useing a B&L 6x24 4200 elite.At 500YDS squriles look like dots. What about a 30MM tube say a 8x32 power,what about that combo? [img]images/icons/confused.gif[/img]

Iron Worker,

I use a Burris Black Diamond 6-24 on my 6mm-284 set and calibrated for 19x with my drop chart. This is where I set up all of my 1000 yard rifles and have no problem at all sniping chucks out to 1100 yards. What power are you shooting off from with your B&L?

THe 8-32 is a great power range on paper but in the field it can raise some real problems.

If it is cool and dry then you can use almost all of the power the 32x has to offer. If there is much humidity at all or it warms up, the mirage will kill you on the higher powers at long range and you will be forced to turn the power down anyway.

This is why I set up my 1000 yard rifles up at 19x. This power will set 2 moa between each mil dot making it easier to figure precise holds and it is also about the most power that one can use all the time so that there will not need to be any power adjustment which in my mind just makes the accuracy level of the set up increase if your not spinning that power ring alot.

In my mind, a 6-24 is a great combination and I also like the 30mm tube, more for elevation adjustment then anything.

As far as picture quality, in varmint hunting light, the top end 1" tubes are every bit as clear as the larger 30mm tube. Only in low light is there any advantage at all and then only with the very best 30mm scopes.

There just isn't that much difference in picture quality, its more a matter of vertical adjustment increases.

GOod Shhoting!!

My scope on my 6-284 is a Simmons 6.5x20 44 Mag and I love it! [img]images/icons/grin.gif[/img] I know what you are thinking a Simmons? But I like it I could use a Leupold 6.5 x 20 but why fix it if it's not broke. I typicaly dont use any scopes over 20x because the the mirage gets pretty bad after that.

Dakor,

I have a mil-dot 6.5-20 Simmons 44Mag on my 6.5-06 AI and I have been very happy with it.

The field of view os less then some top end scopes but it is clear and very accurate as it will steer my 6.5 well under 1/2 moa out to 500 yards.

I'm sure it will do farther then that but I have not had a chance to put it on paper at my 800 and 1000 yard targets yet.

I agree with your comments, for the money, the Simmons 6.5-20 is alot of scope. Certainly not designed for heavy kickers but great for the rounds we are discussing here.

Good Shooting!!!
