260 and 308 palma brass

[Barlow]

Do any of you 260 Remington shooters use necked down 308 Palma brass? If so, what are the pros and cons. Barlow

That is a big case for reliable ignition depending on the powder being used and the temp.

There have been several posts here about that and several shooters have used Palma brass successfully. It allows higher pressures which can be good but also necessary to be very careful to not over due it. Like many things a little is good, a lot is not.

Have a look at German Salazar's primer test:

A Rem 7.5 primer SR primer will light anything a BR2 or 210M will light.

I have often wondered if it would be worth the trouble to use .308 palma brass for my .260. The heavier web/case head and SR primer interest me. I think there may be some work involved on the necking/turning side. I would not mind finding someone to split a 100 with just to see. Hope more folks reply.

Here are my thoughts on the subject. You can, for all intents and purposes, run ALMOST right with a 6.5 x 284 using 140 class bullets out of the .260A.I. AND Palma brass. You will be pushing it hard >> BUT that brass can take it. Now, there is no "free lunch" as the adage goes, and that is true. If you run the .260A.I. with palma brass and run it hard, you WILL burn barrels out just as quickly as you would with a "straight" 6.5 x .284.. SO WHY do that? I am getting my 2nd .260A.I. barrel ready for chambering and will, once again, use "regular" .260 brass (L/R Primers).. The reason is, is I want to get to 2900 f.p.s. with 140 class bullets without PUSHING it to it's limits. That will increase my barrel life significantly and NOT make a lot of difference down-range.. If I want to push 3000 f.p.s. with 140 class bullets, I would simply go for a regular 6.5 x 284>>>fabulously accurate, with very little recoil. These are my thoughts after having 2 / 6.5 x .284's and now on chambering my 2nd .260A.I.

Never messed much w/260 but I'm a fan of Lapua's Palma brass. I use it for that (Palma) with superb results, as well as for forming up 6XC cases and this year a 7mm wildcat dubbed 284INCH by it'd designer Robert Chombart (CG trigger design, CG INCH action, RPA Quadlock & first Quadlite, Millennium actions). Stuff takes it time & again w/o stretched case heads. Were I shooting a 260 I wouldn't hesitate to use it for that too.

Thanks for the replies. I'm inquiring for a friend who has a 260. If I had a 260 of my own I would already have tried it. After I asked the question I did a search and found a lengthy thread from 2011, but sometimes things change. Thanks again, Barlow

Hi Barlow,

I don't know if my experience is 'normal' or if this would be a positive for you, but I am on my 21st loading with my batch of Lapua Palma brass -all of it full power Palma loads (155's @ 3025).

I do anneal after about every other firing.

I have had a couple of neck splits, and about 3-4 cases ready to separate that I tossed, but the primer pockets have held up great -still tight.

I did follow Steve Clark's advice (I think it was him), and shot a slightly reduced load for the first firing, but after that it was full on loads.

Your mileage may vary, but those are my experiences.

I use this excellent brass in my 243, if you neck turn slightly into the shoulder/neck junction you shouldn't have a donut issue.

I was never interested in pushing the .260 hard with the Palma brass, just wanted to try a little stronger brass. So far the Lapua I shoot has held up well at my current loading.

I had the same idea but what is the performance in term of speed and accuracy?

I have about 100 pieces of PALMA brass that has been neck turned and Fire formed in a .260. I do not shoot 260 anymore so if any one wants it let me know. Mike

 

[Hippy]

I went through a similar issue a few years back with the 22 Cheetah--It shot best with IMR 4350 BUT I would get Hang Fires from every primer that was tried except 7 1/2

Good Luck

Everyone that has contacted me about the .308 PALMA necked to .260. In order for everyone to test this in their rifle, and I don't think that I have 100 pieces. I will send 15-20 pieces for you to try. And instead of sending me $ How about donating some $ to AccurateShooter website. How does that sound? So everyone that has contacted me send me your info and I will get the brass out ASAP. Mike
