long range chucks

[maddysdad]

I use to see where some of the 1000ard shooters in pa used their rifles for long range chuck hunting.do any of you do this ang what are your thoughts on the guns that you use.i have seen 7 mm on big cases and 30 calibers also on big cases.

I am only just getting into long range bench rest type shooting, but started shooting Wood Chucks at all yardages back in the 70s. My friend and I would set up a bench with a spotting scope and a number of firearms and we would rotate shooting.

For shots out to about 50 yards we would use a S&W K-22 Masterpiece with open sites. From 50 yards to 250, a Remington XP-100 in .221 fireball. From 250 to 500 a Remington 700 BDL Varminter in .22-250 and for out beyond 500 a 7mm Rem. Magnum. Now that I learning the ropes, I hope to him more out beyond 600 yards with a 6mmBR Norma and a 6.5x47L.

Will just have to see how that works out.

BTW, this is the only kind of hunting I do these days.

That is what me and a few friends do. Nothing like sitting around glassing hills and shooting hogs from a couple hundred out too 1400 or more. every now and then someone gets 6.5X284 but usually it's a .284 and larger. At the moment everyone is shooting 300WSM's RUMS and one 7SAUM

Maddy'sdad -

Howdy !

I'll repeat a rule-of-thumb that I've used for years, when considering cartridge/case/bullet combos for use on " Soybeanus Digestus ".

For consistent clean kills on groundhogs that receive a decently-placed shot:
The minimum energy required when shooting " varmint-type ' bullets is 450ft lb.
I'm aware others might debate that, but it is a good guide line none-the-less.

Using 450 ft lb as a reference energy level, one can review terminal ballistics charts/graphs to see what combo's can provide at least the desired minimum energy @ the anticipated range(s).

Run the math on various .224" cal, 6mm, and even .25 calibre varmint bullets.
For example: What MV is required to still have 450 ft lb on-tap @ 1,000yd , when shooting say... a .224" call 75 "A"-Max ? Or, a 6mm 95Mk ? Or, say a .25 call 90gr " BlitzKing " ?

Then, what case capacity & barrel length will be needed to " get you there " ?

IMHO.

varmint-type ' bullets

This is critical! A bullet that doesn't expand will let them make it back to their burrow for a slow death. Even some bullets, especially at longer ranges/reduced velocity, marketed as "Varmint" will pencil.

 

[maddysdad]

hi,
thank you for your imput on this.i am going of on what I have read from articles in some sights and magizines.i have talked to some people on the pnone about the guns they have used.the 7 mm on the 300 weatherby being one and the 30 cal on a 416 rigby is another.these shoot 168 in the 7 and 220 in the otherusing 30 in barrels a case that tom Drummond made up in the 70s from the 1000 yard mathes at Williamsport are another.

+1, very true.

A lot of things have changed since the 70's. In the 70's they used a lot of 30-378, 7-300, 6.5-300 and various 30 Ackley's. Now they use a lot smaller more efficient cases. Like the 6 Dasher, 300 WSM, and 7 SAUM. The smaller cartridges are just more accurate and in turn get the job done. The old guns are still around and people continue to hunt with them, Mostly longrange deer hunting. There is hardly any new guns chambered in them. A lot of guys switched to big 338's for hunting. The 300 grain bullet has less wind drift and lots of downrange energy. A Dasher with a 105 hunting type bullet will get the job done to 1000 and do it very accurately. Another thing that really changed is that most have switched from Sierra Match kings to Berger bullets. Matt

How do you like the 7 SAUM AI? What type of velocities are you getting from the 162?

 

[Phil]

The 7 saum AI is new to me.

I`m waiting on BAT to get my bolt done so we can chamber it up, i don`t have any true velocities with it yet.

As you can see this is a ever evolving project and the 7mm is just the latest step.....

[daniel brothers]

what would it be if you could ONLY have one...?

 

[Phil]

what would it be if you could ONLY have one...?

Me?

If i could only have one it would be the 6 Dasher.

7.83 twist shooting the 105 Amax, 115 Dtac or Berger.

The Shehane is GREAT but i don`t have much time with it and the 162 Amax.

For a long day of shooting the 180 Bergers tend to make me sore..... ;D

So the 6 Dasher it is, for me at least.

Phil.

 

[maddysdad]

ok,
what kind of damage to a chuck at long range can I expect using a dasher in 6 mm?
I have a 22 br in a shilen ?

[Hydenseek]

Hard to believe the ethics committee hasn't attacked this post yet.

 

[Phil]

The 6 Dasher will put them down, nothing spectacular at longer ranges, but it gets the job done.

What twist is on your 22 BR???

Phil.

 

[Phil]

My 6 Dasher pushing a 105 Amax at 3000 fps has 461.9 ft lbs of energy at 1000 yds.

According to the Shooter Ballistic app.....

I think if you are using the very bestest of varmint designs, like TNTs, SBKs and V-Maxs, in applicable calibres, then 300-ish ft lbs is a reasonable figure.

Many guys that shoot long range woodchucks go for larger calibres, like 7mm and 30's... where there are no SBKs and decent V-Maxs, (the 30 cal 110grs are junk!!) so they to go to more and more ft lbs to make up for poor bullet performance.

And of course, there are about eleventy kadrillion woodchucks that went terminal to the lowly 22 Long Rifle with 90 ft lbs that have a vote in this too

 

[maddysdad]

hi,
my 22 br is 1/14 twist at 25 inchs long.
shooting 52 grain br type bullets.have some powder that is said to move them out at 3750 to 3800 fps.
