Enfield chambered in.308 with a 303 barrel

[desporterizer]

I don't see what the problem is with loading .313" bullets into the .308 case, I'm assuming that they would chamber.

I checked & they will indeed chamber. Just makes for one oddball gun.

Desporter was looking for a genuine 7.62 barrel, and I too wouldn't be pleased with a reamed .303 barrel. So while there's likely nothing wrong with the barrel, I see where you're coming from.

I've shot a lot of .308" bullets in .3105" and .311" bores and haven't had any accuracy issues to date.

Correct for No4 MK1 LongBranch and Brit made No4 MK2

Ardent, most enfields have a groove diameter around >313-315.

No1 MK3 only, with the exception of some Aussie made rifles


I have been shooting .308 bullets in Enfields for years.

Going back to my DCRA days (Dominion of Canada Rifle Association), it was done all the time.

Many team members of the NRA, British NRA that is,
shot the same at Bisley from about the late 40's right up till around the year 2000.

That configuration of the rifle .308 chamber on a set back .303 was the easy way or shall I say the budget way.
You did not have to re-barrel.

There was a chap here, years ago at the Ancaster Gun Show (Ontario) that used to bring in used Match Brit NRA rifles from the UK.
I have seen a least over 50 of these conversions over the years.

In one way, it is all part of the history of target shooting within the Brit NRA and the DCRA.
This conversion is a collector within its own category of target rifles.

Most just shot .308 rounds from these conversions.

If you wanted to shoot .303 rounds out of your re-chambered .308 conversion they followed this simple trick,
which is no trick, use a .308 die set with .303 neck expander in the F/L or Neck size die.

Like us, we did not re-chamber, we shot .308 bullets from a .303 case.
We used a .303 die set with .308 neck expander in the F/L or Neck size die.

You have to use the right bullet with these conversions.

Nosler 165 grn Ballistic tips, wow, those suckers worked flawless @ 600 yds.


We experimented with 2 up to 6 groove barrels, all shot excellent.

I am planning to neck size with a bushing die & use cast. Jacketed. .311 might be correct but only one of my barrels slugs at less than .313 & they are all in very good shape. I think my 45 lonbranch would do well with .308 bullets cause the bore is .301 but why bother?
