Yup Bud when we were at the show with Uggs. I hope the world is still treating you well.
Aye it is and welcome to the site. It's a good one!
I was 'ere before you my friend... I have only just found this thread looking for something on tinterweb.No second place winner

No, I have the slot to buy the 7.62 now, but should it not perform as I want, 6.5 Grendel is only a re-barrel away.

Well if the 7.62x39 works out ok nothing, if the plan fails who did your build, and what is it based on.
I'll stick my oar in as you seem to feel a deer legal 7.62x39 is an impossibility, please explain why this is, and list all the loads you personally tried that failed.
I will mention one load, taken from the Speer Reloading Manual 12th edition, Powder AA1680, 28 grains of it , under a Speer 125 grain soft point, 22 inch barrel 2544fps.
(max load in more modern books is 29.5 grains and still not a compressed load)
There is room in some (but not all) cases for another 1.5 to 2 grains, and with a bolt action proven to safely handle more pressure than an AK or SKS gaining a little more ft/lb should not be that hard.
If I'm wrong I'll hold my hands up and say so, it will still make a nice light carry rifle for fox and small deer until I can afford a calibre change/re-barrel.

I never said impossible , just highly improbable. Never had one, not interested, do have a 30-30, not in the same ballpark. Thats what got me going, the widely repeated misinformation that they are comparable. Bigger case, more powder, heavier bullets, over 100 years of pedigree as a deer rifle.
We can all bandy data. You've not got one, neither have I. Archer does, but trusted an RFD to reload for him who was confident it would be deer legal. Not small deer (1000 fpe) but big ones (1700 fpe), which includes Roe in England. Perhaps the same RFD who sold him the rifle
I asked a simple question, how did the loads chrono, even offered the use of one, and it all went silent, until now.
I also pointed out some other loads that might just work.
That speer bullet you mention is also AFAIK the only one available, correct for calibre and deer legal. Painting yourself into a tight corner ?
Anyway I give up.
Keep it for the foxes and munties etc.
BTW I don't doubt at-all that it puts down roe most effectively, but I doubt its legality anywhere in UK for that job. As for the proper big deer, please don't even think about it.

Not the only bullet, but yes they are limited, especially around here it seems.
I agree it may be a struggle to get there, it may never get there, but it will get a lot closer than a short barrelled .243
Personally I think it will make it, and will be no harder to do than getting 1750ft/lb from a 6mmPPC, which was not a problem.

Good luck, you obviously like a challenge, if you get the chance, talk to Bruce Potts, ISTM he has also tried all these things. And given up.
Keep us informed.
Still waiting to hear from Archer...
It was converted by "Rifle Craft" in Norfolk. It is based on Archers old CZ527 that was 7.62x39.
It has a 22"button barrel which is threaded for a Mod also brought from RC, I had to reverse the mag spring to get it to feed properly.

Suggests 6mm ppc is also not easy, took a 26 inch barrel for him to just scrape in. By 6 fpe
Grendel appears to be the way.
As I said, I have a responsibility to check out any suggestions so I did contact the guy who reloads for me and he assured me the ammo was legal.
However, as I wanted to look more closely at the round, last month we made up some fresh rounds using his manual.
No not chrono'd yet but when I read your post#47 thought it would be good to meet up and, as you don’t have any hands on experience of the calibre, research this together, but, between starting a pm and posting it up popped #49 and tbh having read that, I’ve decided that I won’t involve you.
Cheers
Fair enough. Please don't take my words as personal criticism. You've had a year to get your RFD reloader to chrono the load, and you are cutting it fine now for the start of the buck season. It would only take ten minutes to know for sure, one way or another.
If he is still guessing at the results based on the fairy tales in load manuals and perhaps doesn't even have access to a chrono, then I would proceed with great caution.
Any RFD supplying reloads will be well aware of the (il)legalities. Unless he has submitted a batch to the proof house for pressure testing he is breaking the law. It doesn't actually cost very much.
Advising and assisting you in making your own reloads might sidestep that problem.
You have managed to get your rifle conditioned for large deer, rather surprised the police let you have it because the data they use would tell them it was unsuitable. If alternatively you can't find legal factory ammo, nor convince them that you can reload to the necessary level with published data, you would usually expect to be knocked back.
I'd be happy to give an opinion on your new load, if it has changed. If it hasn't changed, I am confident it is unlikely to deliver.
I did suggest a load with Reloder 7 that had promise, I even have a tub of it. Also I reckon it could be done with Vectan SP7 which is a very dense powder of suitable speed. These would be over-max loads.
Sorry I misinterpreted buck732's post, I thought you had got rid, which you must admit was the obvious interpretation.
Have you found a local replacement source for the components ? Perhaps ACGuns could get them in for you ?
This thread has been running for a long time. The one thing that nobody has posted is that they have personally managed to load up to the required level, and have the chrono data to prove it. Everything otherwise is just speculation, some better informed than others.
Good luck.

As you said this thread has been running for a while now.
I wouldn't expect many people to have bothered trying to prove it can be deer legal to be honest.
As far as I know there are two owners of this calibre on the forum, and one prospective owner, me.
To be honest I'm surprised you have bothered to keep reading, as
Neil.
Don't be shy, let us know how you get on, facts and data please.
Very interested to know if you manage it, from a deep interest in ballistics, internal and external.
Not interested in trying to push a sub-marginal calibre to turn it into something it was never designed for.
I don't even think the CZ527 in such an oddball calibre is so desperately cute that I would ignore all rational sense to justify having one, nevermind two. Mind you, if offered one in .223 full stock at the right price I would ignore my rational judgement.
Please don't make me wait another year to hear ... nothing.
PS: AFAIK the only other rifles offered in the calibre here, are straight pull AKs and Ruger Mini14s. I have shot these, fun but simply a platform to shoot cheap milsurp ammo. No aspirations otherwise, fine with that. The 527 carbine is similarly offered in the USA as a fun gun to shoot cheap ammo.

Edgar's have none, even the yanks have none, CZ not making any at the moment due to a huge military contract they have.
I have been chasing one since February, looking like I either wait till next year, or build one.
