I took a long shot ....,Warning Dial-up users BIG Picture)

and MADE IT ! This afternoon late and after work I went out to my favorite honey hole for groundhogs. The hay had just been cut last weekend and rolled Tuesday so the groundhogs are real shy and nervous. I had been popping a few coming in just a few feet into the fields from out lying taller grass and brush. From my bench on a trailer that I keep parked on top of a ridge overlooking the fields are a few holes that are over 500 yds. but most are within 300 yds. I had been hitting them pretty good between 300 and 400 yds. but couldn't connect much further for one reason or another until tonight. I have been using my Remington 40x in a Shehane Tracker II stock with a 25" Pac-Nor 11" twist 20 Tac barrel with a muzzle break. Mounted on the rifle I have a Leupold 6-20X Vari-III with 1/4" clicks. I like the muzzle break not cause the 20 Tac is a hard recoiler but because I can see my hits,and misses) with the 20x power scope shooting off a Harris BR bipod. This rifle likes H-4198 and 40 gr. VMaxs. Anyway, a storm was moving in from the next valley over and the wind was getting up and everything was getting cooler and darker and I saw these two hogs two hay fields over. I lasered the closest tall grass at 620 yds. Then estimated the wind and clicked 4 clicks of windage and 30 clicks of elevation.

I missed the first shot cranked more windage and still had one hog still out, missed another shot and both hogs had run off now. I ended up clicking 14 clicks of windage and 33 clicks of elevation but had to wait 15 minutes before one of the hogs stepped back into the hay field. The wind was getting up and then dying so I tried to squezze my shot off in a wind condition just like my last missed shot and finally I had what I thought I needed and squezzed it off and to my real surprize the 40 gr. VMax connected and I got to see it all in my scope. When the ghog's tail started wiggling up in the air I knew my shot was good.I drove over to the hog and lasered 618 yds. back to my bench.

Nice! Great shot of the fields and the sun too!

Man shrink those suckers down to about 800 pixels across!! :)

What's the BC of the 40grain Vmax...

6ff993m.jpg
 
The BC of the 40 gr. VMax is claimed to be 2.75 by Hornady but I use 2.65 in my Palm Pilot with EXBal ballistics program and it seems to work for my purposes. I think this 40 gr. bullet does have the highest BC of the commercial bullets from what I have heard. This Pac-Nor 1-11 " twist barrel is the first barrel I have owned that liked the VMax though the others preferred the Sierra 40 gr. BK.

That's pretty high when you consider that it is only 40grains. Does anyone make VLD's for the 20cal yet? That could be interesting.
 
Yes, I have heard the 57 gr. BT that Don Unmussig makes called a VLD but I am not sure it is a "true" VLD bullet. I have shot his 50 gr. bullets and they must have a BC of around .300. Anyway, he makes excellent bullets.
I am in the process of building a 20 PPC with a 9" twist and I am planning on getting him to make 55 gr. BT bullets for it . I think the PPC case should have about the "right" capacity for this caliber. If the 20 PPC is not competitive in 600 yd. IBS BR matches I'll still have a heck of a long range "critter-getter".

That is some fine rifle shooting. The fact that your experience out there told you to stick with it after the first couple of misses and go ahead and set your scope for a better shot is the trait of a man that knows his rifle. Most cannot figure that in their head. You were getting close to a 600m shot on that one, 658yd for 600m. Looks like from the pics and you said after work that it was approaching a faded light situation. How did the scope look to you as you scoped the field?
I started a Mid-range Thread on the Comp Page where your rifle would fit right in. Great shooting for a Pennsylvania Yut.

Sounds like a nice plan. However, I'm not sure I'm sold on the smaller-lighter projectile/cartridge combination for long range shooting competely. The recoil savings seems very nice but I just get the feeling that once you much below 224 diamete bores you tend loose alot of potential in the drag/mass ratio of the bullet and potential BC's become lower. Of course this is why I was curious as to what if any VLD development has been done for the 20 caliber lately considering its popularity. Myself I think 6mm or 6.5mm bullets seem to off the best compromise in BC and recoil given their most efficient cartridge combinations for average shooter. However that is just me. But I'm always interested in changing my preconcieved notions so I would love to hear how your 20PPC of the future or the present 20tac work out in varing conditions.

Clearly, my biggest problem with favorite rifle is a low twist rate something I intend to change on my custom rifle, but a .223 with 1:12 twist to me is worthless beyond 400yards in wind. Now I don't shoot varmints or any animal for that matter. I'm strickly a target shooter but I find that 52grain HP's are great up to 400-440yards but after that they're as squirrelly as they can be and they the same basic BC as your 40 grain 20tacs but I'm sure the 20tac is shooting at 3400-3500fps almost with 40grains where as my lowly 223 is only doing 3200 which is of course a great benefit in both drop and deflection. But still I wish to go up to the 6mm in a 243AI or perhaps a 6-06AI maybe 6.5x55AI Swede I'm not sure right now the 243AI is winning out. I would love to know what your experiences are with the 1:11twist 20tac.
 
Might take a good look at www.swampworks.com. He now carries some of the old 22 cal. JLK Low Drags, with the following BC's,as far as i know the highest BC's available for their twist rates)--

52 gr/14 twist/BC-.302

60/12/.339

65/10/.397

Thanks for the help. I'll have to look into them... That 60grain sounds perfect for 500-550 yard work...
