Enfield No 4 in 6.5x57r or 6x57r

Post by andym79 » 24 Feb 2019, 10:56 am

Hi guys I have an Enfield No 4 with a worn barrel. I am thinking of barreling it in 6.5x57r or 6x57r i.e a 6mm remington with a rim. The latter would be made using 6.5x57r brass.

I am looking for a varmint rifle good for 200-400 yards.

I would prefer to go the 6mm route, I am thinking 1:12 twist with 70 grain bullets.

I think the magazine should work well with it, it seems to function okay with 7x57r, might need a tiny file as case is less tapered than 303.

What do you think, should it work.

I think starting loads would probably be max for this action though so would give up 200-300 fps compared with 6mm remington.

Thanks Andy

What do we think that should work?

Well, my suggestion is to rebarrel the No.4 to 303 and get a 22-250, 25-06 or a 243Win. for the varmint rifle.

I know someone who is playing with 7x57R conversion in a Enfield, a new barrel is all that is needed basically. If the rifle needs a new barrel, converting caliber at that time would be logical.Considering projectile choice in 7mm it makes a lot of sense. As for the 6.5’s it sounds like a good idea depending on usage I guess. Be interested to hear how that goes. Cheers

My only concern is the magazine and feeding, the bolt will be fine as will the barrel shank size and action strength. But I put three 6.5x57R in there earlier and it wasn't feeding well at all. I am guessing the magazine will need altering or replacing. Looking at the case I thought they were sure to be okay, the rim is almost the same as is body size and length, only the extent of taper really differs.

Does anyone have a hint for the magazine?

Why not just go 6mm-.303? Then you know it should feed fine.

Back in the day 303 was wildcat into all different calibers. I’m not sure about 22, but of the top of my head they went from 243 up to 375 . Back in the day lots of fellas had modified 303’s cause it was cheap compared to a new foreign made sporter. And it was uniquely ‘straylan. Lol

Mostly correct, kind of.
Yes there was a 22/303. From memory it was called a 303/22 Falcon.
All these wildcatted 303's date from an era when the Australian government policy was to protect Australian industry rather than let it die a natural death as is the case now.
The imports were expensive because they were subject to stiff import duties and quota limits. As these restrictions began easing in the late sixties the 'poor relation' sporterised 303's became undesirable and there was a period when they were unloved and unwanted to the extent that sometimes you couldn't even give one away.
Those days are well and truly gone.

Had a SMLE Mk 1 fitted with 7 X 57 R barrel, great scrub gun for pigs. Pressure within SMLE limits, 170/175 bullets.
