Calibre Decision!

Hey Ladies and Gents!

Greetings from the UK.

Have used a .22-250 for fox and long range vermin for a couple of years, and am after a longer ranged rig... you know how it is!

Am now in the market to have a long range rifle built, am thinking of a 6mm or 6.5mm platform. So would a factory .243 Remington 700 Varmint action in an AICS be adequate or is it worth going for a custom barrel and thus pursue the 6.5X47 Lapua?

Bear in mind getting these things done in the UK costs easily double what you chaps pay! I hate the UK!

The reason why I choose these calibres is low recoil and excellent long range performance.

Am after the lowest recoil possible to try and spot my shots, although the rifle will have a sound moderator and be fitted into an AICS... weight will be my friend.

a) how do the .243 and 6.5X47 compare in terms of recoil? In a heavy rig anyway?

b) what bullet weights could i fire from such calibres and what would be the effective range of both in terms of fox shooting?

cheers, ed

Re: Calibre Decision!

Sounds like your ready to move up. Nothing wrong with either the 243 Win or the 6x47mm or 6.5x47 Lapua. What you might want to consider is; “brass”… that you already have; 22-250 Rem. I did a Weatherby MkV miniature {early} action’.., that was an originally a 22-250 Rem. I re-barreled my Wby to a 6XC, a very nice cartridge. If I had to do over again I might have went with something like a 6mm-250 mainly do to all the brass I had…. and its availability. Now hunting performance of all the aforementioned cartridges are all about the same. As for long range target work’…, well that’s where the beer(s) and the conversation kick in.
On recoil, {depending on bullet weight} there all about even; with the 6.5’s having a tad more there’s nothing to be concerned about. As for twist; I think I’d stay with 1-12 for general hunting, 1-14 for varmints and 1-8 for target at long range.
Good luck.

436,

thanks for your response.

my thinking is that if a remington 700 varmint action and barrel will do it with the .243 then great.

for coyotes, for example, with a 87 - 95 grain vmax (.243), what would be the longest range you'd have a go at... providing a .5 MOA rifle and shooter?

my thinking is that the 6.5mm would give me more range and power if i ever wanted to push the envelope... plus a custom barrel would result in great accuracy with handloads.

for coyotes, with the lightest 6.5 bullet... is it 100 grains?... what would you reckon would be a humane distance?

cheers, ed

Have you looked at the 260 Remingtion (A 6.5 /243).

You can buy the rifle from Remingtion if you don't want to build a custom.

Good bullet selection, plenty of brass =243,260,7/08 and 308 and factory loaded which means
standard reamers,standard dies and plenty of reloading data.

This round is very popular with the recoil sensitive folks and devastating for varmints and deer
size game also it has a good following at 1000 yard matches.

I would have one myself if I didn't already have a 7/08 (Very close).
