Thread: Wanting to build a new varmimt rifle

I've decided to have a new varmint rifle built from a Remington 700 that I have currently in .243
Problem I'm having is which calibre to re barrel to using the .308 bolt face.
I'm leaning towards .20Br. Using a trueflite match barrel.
Any suggestions or advice gladly accepted

do you reload

How far do you plan on shooting? If out a far way why not stay with 6mm and heavy for cal bullets?

I would do a 1-7 twist 22-243 and run the 90vld

have a play with some 6mm varmit loads

Have tried a couple in the .243 pencil barrel. 58g Sierra and 87g v max. It doesn't like either of them

Good old 22-250, the heads the same plus if you ever need it ammo is everywhere unlike a 22 243 get a fast twist so you can chuck heavier pills as well and everything from rabbits to deer is sorted.

I have a 22br. 1:8 with heavy pills they only need to be about 100 fps faster than the 6br to be equal. less recoil. less powder than 22-250. and really accurate.
the 20br is not the go I hear from a guy with both. I forget why, probably barrel life and pills too light.
you won't be disappointed.

Me personally the .22-250, about to re-barrel mine to a 1:8 or 9 twist at 22" so i can throw some heavier pills, had it 12yrs and love it, just want to be able to have options.

Be it 40g to 77g she will be great to shoot once done.

That said I have 60g & 70g pills for .243 but have just shortened the barrel, handy for close work on smaller critters.

Thats a nice rifle dude,shame it doesnt like those varmit loads.i use the 85 gn hollow point from hornady,works well on rabbits to reds.i kinda agree with the guys suggesting the 22 250.

I d go 20 br. A mate has one and shoots magpies at 400 yds pretty easily . I have a true flight barrel waiting to be rebarreled soon in that calibre.

For long range varmints I have been most inolressed with heavy 6mm projectiles in a range of cartridges (6br, 243ai etc) 105 amax was very impressive. 6xc is in my head as something I want to build but got a few other things on the go at the moment

I have heard that sum of the short BR cartridges, are difficult to get to feed well from the magazine, I have had problems with the .17 & .221 fireball and one 6MM ppc, my sako 6PPC is fine. As is the single stack L46 sako in .17 fireball, I sold of three Remington's, for poor accuracy and feeding/jamming. two fireballs, one PPC.

so single shot use, or magazine feed, hunting rifle, ?

I likely look at a fast twist 22-250 or AI, for a long range varminter, or a .243 fast twist for a more dual purpose rifle. 6xc might be a good option as well.

20 BR is way over bore, you will smoke the throat in no time, unless shooting 50gr plus

I have a 20 vartarg on a cooper MTV, and get 3750 fps with 18.5 gr H4198 and a 32gr blitz or v-max, 39gr @ 3450 with a grain less,

The 20 br is not much more over bore than the 204 Ruger. And barrel life really depends on how many rounds you are going to fire consecutively in one session.i don't see why shooting heavy pill would lengthen the life of your barrel.
You could also go 6mm-284. Easy to neck size down the lapua or Norma brass . Is magazine feeding an issue when you single load for just shooting the odd round at a distant target?

If you are going to do volume firing then stick to the 223.
