Re: 1000 yrd qualification

At 69 years young, I can't remember anything that wasn't uphill, so the terrain is familiar.

The date is esablished (May 1), so we take the wind we get. Meet at 7AM so that is the quietest part of the day. Don't know how many others there will be but would guess maybe 10?

I am somewhat familiar with ballistics software as I developed an extensive external ballistics program that was used & sold internationally in the 80's (prior to Windows). It was used in Virginia and White Sands by the military and made available through Chrony with their chronograph. The military said it was the most accurate of anything available to them at that time. Hence the handle "Ballistx" which was the name of the program, as it couldn't be more than 8 characters long and work in DOS.

But I didn't have a 1000 yard range available to do any actual range work. However, I have taken a few 1 shot kills on deer in excess of 600 yards. That was with the 06 and the 2x7 Redfield with the accurange.

Fortunately this isn't a once-in-a-lifetime chance to qualify. Just need to pick the best options I have on the equipment I have now. And all this info certainly helps. So, Thanks MUCH for the input.

Ballistx

Re: 1000 yrd qualification

Ballis- the three are real close balistically with the nosler partitions. one of the great great hunting bullets. for most target shooting they are not concentric as a match bullet. it is geometric ; 1000 yards is a long ways. shoot a 115 berger in the 25-06, or a 115 balistic tip; a 130 balistic tip ; or 135 match king in the 270; or the one of the ones i mentioned in the 30-06. if you don't reload ; you need still should shoot one of these from a factory load. what scopes on each? have the triggers been adjusted? easily done google "remington crisp". are you hunting in new mexico?? from new mexico?

If he's going to go with factory Ammo I'd suggest Wincherster Supremes and Hornady.

I've had great luck with both. It all depends on what his bbl likes best.

Re: 1000 yrd qualification

The first thing you should do is dial up on your elevation turrets with each scope to see how much "up" elevation you have left from your normal zero distance.

Then run the numbers through a ballistic calculator to see what is required to get the job done out to 1000.

You will soon work out if it is possible with the scopes that you have.

If your scope has enough travel, shooting out to 1000 in 100 yard increments is quite easy, so dont stress over it. Its fun.

Re: 1000 yrd qualification

Are you going to be able to test your load at range before or not? I have had custom turrets made by leupold that where way off at 1000. That was with todays best eguipment to work with. Just because a ballistic program says a drop doesnt mean its right, it usually is'nt and needs to be field verified, for sure at 1000.A though I was busting rocks yesterday out to 1016 and my intial dope seemed to be on, which is rare for me.

Re: 1000 yrd qualification

I have worked up reloads for all three using the Sierra boat tail bullets and that is what I will be using. The 25-06 is a little more accurate than the 270 (.75 vs 1 at 100 yds). The 6x24 scope has the range with some to spare. I haven't tried the other 2 that are in the 4x16 and 6x18 but would guess they do.

We will be moving back from 600, 800, 900 & 1000 so there will be a chance to verify and compensate for the tracking errors. Don't get disqualified for short shots until the qualifying 10 rounds.

The scopes don't have mil-dots.

I am leaning towards the 25-06 as it is lighter recoil and I know that it is good with the rounds I have worked up. Will just need to make up my mind and switch the scopes if that is what I decide.

I won't be using the partitions for this, just for hunting when the time comes. And that I have decided will definately be the 270.

I have rung it out on my ballistics program. If the muzzle velocity is correct, I have 100% confidence in the trajectory being accurate. That program was rung out by the 50 caliber shooters association back in the 80's out to 1500 yards and at all elevations. They said it was the only one that confirmed their actual findings relative to elevation. And we are at about 5,500 ft elevation at the gun club.

I am currently in Albuquerque and will be shooting about 20 miles NW of Albuquerque and hunting Oryx on the Stallion Range the end of September.

I don't have the time to set up the chronograph and develop loads before the qualifications, so will go with the ones I have and have range trajectories for already. I always have them taped to the side of the rifle ahead of the trigger for instant confirmation when hunting.

I will have to decide this evening on the scope situation as tomorrow is the only time I can actually get out to the range and run them out to 300 yards to make sure they are on there. Just need to determine now if it will be the 270 or 25-06 as primary and will take the other, with the required 100 rounds, along JIC. Always like to have a backup.

Thanks again for all of the input.

The value of an accurate weapon with which you have good accuracy, lots of experience, and absolute confidence can never be over state.

One thing. You will find that there are an enormous number of better bullets than the Nozler Partition for long range accuracy. With the flat base and odd sectional density they are very high drag, and tend to get very squirrely (read unpredictable) beyond about 750yds. Perfectly adequate for things like Elk but for smaller species I can give you a list of at least twenty better bullets beyond that range.
