22-250 or Swift & 22 cal VLD's?

[Chopaka81]

My goal is to build a LR Pairie Dog / F-Class rifle.

I recently read the article that appeared in varmint hunter magazine regarding the use of 75 gr & 80 gr VLD's. The bbls were 1:8 twist. It is a very intriguing idea - wonder if anyone here is using them?

Apparently some are having success in F Class competitions too.

I have a fast twist 22-250 and shoot 75gr A-Maxes. The BC is reported to be .435 which is just okay. If you want to shoot the 90gr Sierras you better have a 1 in 6.5 or 1 in 7 twist barrel.

I think a fast twist 6Br or 243 would be a better choice for varminting and open F class. A 105gr A-Max will stabilize in most 243's with a 1-9.25 twist barrel and they have a BC of .500. If you get a 1 in 8 twist you can shoot 107gr Sierras which stay above .500 all the way down to 1600 fps. ...Also, 243's are just wicked on P dogs.

I don't want to talk you out of the fast twist 22-250, after all I do own one; but with that being said my 243AI is my go to gun for long range varminting.

TAC,
Good point, one of the contributing factors for choosing the swift is that I have dies for it.
You bring up the 6mm's... I do have a Ruger #1 in 6mm Rem. It shoots 5 shots into the 4's with the Sierra 100gr SBT. I will do a little more range work, perhaps switching the scopes out might be the proper solution for the time being. Not sure what twist the Ruger has, it is a bi-centenial rifle. I will have to look into that possibility. Exbal here I come...
I had such a great time shooting PD's that I am itching to go deeper - much deeper.
Thanks for the advise!

Just ran the numbers on the Sierra 100gr GK @ 3000fps vs. the 107gr MK @ 2900 fps.

Looks like the MK has about 3" less deflection with a 10mph cross wind the the GK @ 500yds.

Not sure if I would be able to tell the difference in the field. Looks like one could benefit from the MK's higher BC in energy. I will have to see if the #1 will stabilize the MK.

Very interesting indeed. Looks like I may have to do a trigger job in the #1. The war dept will love that...

I don't know if you've messed with your #1 trigger before... they are a difficult to work on and a pain in the butt to get to. Then again, If you're getting that kind of accuracy out of it I wouldn't mess with it.

Depending on the age of your 6mm you may have a1 in 12 or a 1 in 10 twist barrel - most likely the 1 in 10 if you're stabilizing the 100 gr SBT. Try the 105 A-Max first, a lot of guys can still stabilize those in a 1 in 10.

If you're thinking of re barreling the 220 swift don't let the dies be a consideration since you can sell then on this site along with your brass. Also do rule out the 115 DTACS from David Tubb for an all out long range rifle... DavidTubb.com.html

I have a 22-250 with a 1:8 twist Pacnor shooting 80gr smk's at 3230fps. This a really good set up for long range pds. There is not much difference with this and a 6mm with 107's at 3050fps out to 1200yds. This is actual side by shooting with both. I think you would like it, however the available brass might be an issue. If doing this again I might consider a 22br or a 6x47 in order to use Lapua brass. Good luck.

John--Lapua is supposed to be coming out with 22-250 brass soon.
