Does anyone use 7x57R or 7x65R?

[kombi1976]

I'm interesting in chambering 7x57R or 7x65R in a custom large frame Martini and am wondering whether anyone here uses them.
What experience have you had with them and how far are they behind their rimless parent cartridges(i.e. 7x57 & 7x64 Brenneke)?

The 7x57r is the same as the 7x57 except it has the rim for being used in the english double rifles for extraction.  I believe the two 7x57 / 7x57r are equal in speed/power except one has a rim.  The 7x57 round is one of the flatest shooting rounds there is and the 30-06 was designed from it too. If you go to a ballastic caculator and punch in the numbers with a 125yd zero you will see its path only varies about 1/2" to 5/8" the whole distance out to 125yds. With ballastics right in the pack of the lower 30 caliber rounds  it sure makes a 7x57 with the lesser recoil very attractive. Now how would we rate the 7x57 round is the question?  I think its for elephant size game(max) and down right? I like the 7x57 and i think its an old overlooked round that can still hold its own even to today.  I think its a good choice picking the 7x57r for your gun. But the 7x65r would push the heavier 7mm bullets a tad better than the 7x57 would.  To me the 7x57 is limited to 140gr to 150gr max. while the 7x65r you can go up to 175gr. with more power. It depends on what bullet weights you plan on using as to which caliber you pick.

Hi All,

    Srry to get in this so late but the 7x57R has nowt to do with the English gun trade but an awful lot to do with the Drilings and combination guns favored in Central Europe.

    The 7x57R is a slightly lower pressure cartridge due to the Break action guns it was more often chambered in, the rimmer version operates at 43500 psi whilst the rimless operates at 49300ps that is according to the Vihtavuoi first Ed manual. Hope that helps Kombi :wink:

I hate to say this,but I just bought 10boxes of 7x57 with 180grain,from
Aim.

[kombi1976]

180gn!!!
What brand ammo is it?
They must be long bullets.

I have been looking into another barrel for my Encore hopefully next spring or late this fall if the wife gets the job she's interviewing for :?: Please...Please...Please!!!!  Alright that was pathetic it won't happen again.

I just got my 9.3 x 74R from MGM and I'm going to get rings and a forend at Cabela's tonight so I'll be able to shoot it later on this week or this weekend.

I like the rimmed rounds in the Encore for both extraction and looks, like I've said in my other thread they lend themselves well to the Encore.

I'm even kicking around the idea of having one made in either a 270 x 57R or 270 x 65R.  Would be interesting to see what velocity I could get with 140 gr Accubonds.  I could always just neck down the 7mm brass and have some dies made to accommodate this wildcat.

Oh well the money isn’t even close to being anywhere close to my pocket so I’ll just have to dream for a while.  Since I have a 270 Winchester I though about getting it re-barreled by MGM to either a new 270 or 270 AI.

Then again dreaming is free and the wife can’t stop me from doing that.

Josh, if you're interested in having something really interesting have you considered the Aussie wildcat the 303/270?
Forming and reloading dies can be had from the Aussie reloading company Simplex.
It's rimmed and should suit the Encore well.
And if you feel you need a little more oomph there are improved versions like the Canadian wildcat the 270/303 Epps Improved which has a 35 degree shoulder and less case taper.
While neither will match the 270 Win the Epps cartridge isn't too far behind and with the nice strong Encore frame you can load it up well.
A friend has a 6.5 Epps in a Martini Henry action and it is a deadly little number.

Then again dreaming is free and the wife can’t stop me from doing that.

I know that story well.

I'm assuming that you are basically just necking down the 303 British case fore this.  Interesting in that the 303 brass is just about everywhere, definitely going to take do some more in-depth research.  This might be the way to go!!  The improved version sounds like what I'd be after, I'll do some research on these couple of rounds and see what looks the best in the balistic department.  Thanks kombi1976 for the info.

Can't wait to get this thing to the range...I just got back from Cabela's with a new forend and Warne rings.  I have a brand new VX-II 3x9 x 40mm ready to be mounted just need to modify the forend with my dremal tool and get the scope mounted and away I'll go.

[kombi1976]

You're right.....you neck the 303 down to .270 cal(usually in one pass) and then fireform.
If you're seriously interested in the full range of wildcats based on the .303 British case you should order from Steve Redgewell(an acknowledged .303 & SMLE guru) a book which from memory is called "The Accurate Lee Enfield".
It features a whole chapter on the Epps range of 303 Improved cartridges which were created by Ellwood Epps in Canada during the 50s.
Epps was an individual and innovator and made quite a mark on the hunting industry in his time.
His shop is still in business.
Whatever the case you can definitely get reamers & dies for any of his cartridges.
Anyway, when I get home from work a little later on I'll PM you the details on how to get the book.
