Hi All
I have recently acquired a 1st model Newton, and RCBS dies. The dies came with some brass, which are devoid of any brand name or calibre markings, so I can only assume they are resized .30-06 surplus.

I intend to test loads with Win 760 (that's the powder I have, won't be getting more) and various Nosler and Hornady projectiles ranging from 100-120gr. I will start with a 6.5x55 max load of around 45gr of 760 and work up. Has anyone any experience to suggest this is not a good starting point?

With regard to case trimming, I have read (Can't remember the source exactly but I think it was either a Handloaders Digest article or from Ken Waters, someone correct me) that 2.40" is sufficient trim length, a fraction shorter than original specs. I usually use Lee case trim gauges but I do not have one for this length, and can't get my hands on a 9.3x62 gauge - serious supply issues) What is your experience with varying trim length?

I will also source some new brass to reform new cases, my preference is Norma 25-06 or 270, but will see what is available. What are your experiences with forming cases for the 256?

Thanks in advance
Regards
Ben W

Just the aside... Big congrats" on owning a great rifle, that Newton edition of 1916! Particularly so if "original" condition. Only about 4K total production & of those, most altered in the century plus 'out there'! My own original in "30 Govt", a gem!
Best! John

Thanks John. The condition of the stock is best described as 'sad', with a considerable crack around the action which needs some kind of repair. The bore looks reasonable, but hard to determine for sure until bullets go down the tube and groups can be measured.
Unfortunately It also has an aperture/peep sight fitted to the rear of the receiver, which I suspect is not original. This modification, along with the poor woodwork, makes it something of a 'beater', but I'm pleased to own it anyway. Its also the only one I have ever seen here in New Zealand. There may be others but Ive never seen one.
It certainly won't be a safe queen, I intend to take it walking and put a deer or two in its sights. I'm excited to get some rounds loaded up and see how it shoots!
Are we allowed to post rifle pictures here in the reloading forum or is this too off-topic?

Thank You for posing the question.
While I can not help with an answer or even an opinion, it did lead to a bit of Google-Fu concerning both the cartridge and the rifle.
Given the interest this might generate perhaps it would be best to start a separate thread in another forum although I don't know which would be best for it.
For myself, I would like to see pictures and ask a few questions.
If you do start a thread, please advise as to where you place it.

As for the cartridge and your question, the bits of info I did find revealed that in its original configuration it closely matches the now current 6.5 Creedmore in performance, albeit in a larger envelope.
The general consensus in the articles I read point towards IMR 4895 as a goto but most of those articles are quite dated, more modern powders might work as well or better.
As a start point though, how does WW 760 compare with 4895 in the burn rate charts?

Hopefully, someone who has hands on with this cartridge will respond and give some tips for you.

the WW760 powder will definitely be on the slow side of performance for this size of case. something in the 4895 burn rate range might do better. another good idea would be to check the barrel's rate of twist; knowing that will help with choosing the most suitable weight of bullet, for accuracy.

I have a 1925 Meeker (long story but a Newton offshoot) in .256 Newton. Chas. Newton was going for speed and designed the rifle to shoot relatively light bullets. I had no success getting 140's to shoot well and settled on 129gr (I think...away from my notes). Performance and loading are very close to the 6.5-06. I have brass converted from '06 but did score a bunch of properly marked brass (Qual-Cart, I think) all brand new. I don't know about trim length as I've never trimmed any...yet. For powders, I am using 4831-SC and it seems to work well.

Thanks for the update! These rifles are sufficiently rare, just owning one in "shooting condition" obviates the need for any apology... At least such in my book! I agree that "how it shoots", likely the 64 dollar question as intent to 'field it'.
Can't speak for this Forum, but probably the GB Commercial & Military Sporting Arms Forum, would a good place for photos, w/link here. I'd sure like to see your specimen! You do that & I'll post up a few pix too. Maybe throw in one or two of my Buffalo Newton! Needs a few small parts and... Dang! Walmart's still "out of stock"! :)
Hope for 'rendezvouses' there! Get some dialogue started on the Newton subject.
Best!
John

Nonte 1967 page 297 lists trim length of 2.457". The powder loads he lists use 4064 up to 120 gr bullet, and 4350 for 160 gr bullet. He cautions on checking neck diameter after resizing from 30-06 but you may be OK using .270 cases (neck spec = 0.289").
