Is anyone shooting a .28 or 7mm other than 28/30? If so what calibre and what twist?

Thanks in advance for any input.

I shot a 28-35 for four plus years in competition with great success. Sold it to a friend who is still doing the same as I move onto shooting a 25-35 in competition now. 
The 28-35 has a Douglas 12 twist barrel, 12.3 grains of 300MP, Fed.LP Magnum Match and 16-1 alloy, Bullet is a 154 grain Spitzer.

Ballards may be weaker,
but they sure are neater!

Have a Pope Ballard chambered in .28 Special, which is based on a .32-40 case necked down to .28 in bottleneck shape. Hard to say what the twist is as it's a gain twist barrel. It's listed in the Pope books as a .25-35 blown out to .28, but brass in boxes that came with the cased set is marked as .32-40 and the box is labeled ".28/32-40" so I am not sure the book is correct. The barrel is marked 18/1.41 which would indicate it starts as an 18" twist, and I believe is about an 11 twist if I did the math correctly?

I have a HW in 28 G&H. A 32-40 straight tapered to 28.  Looking for a 180 gr or so tapered mold for it.  It has shot well at times with a 148 gr Accurate mold.  About 9.5 twist I think.

What is also nice about the 28-35 is Hornady is making new 25-35 brass and all one has to do is expand the neck. I have now lost count but we now have at least six rifles chambered in 28-35 in our Schuetzen group. What is also nice is pressure has been a none issue. I have taken mine up and well beyond 13 grains of 300MP breech seated and still minus any pressure signs. But the bullets I have tried just didn't like being pushed that hard so accuracy did suffer. I found it to be real user friendly, easy to get to shoot, and always remaining very consistent. It has provided me with allot of honors over the years shooting benchrest and for me it was not only a great choice but also being extremely enjoyable to shoot.

Interesting and I have some unformed Jamison 25/20 ss cases which would make that an easy process. Thanks for the Idea.

Im out here in Australia and, at present, the Hornady brass is unobtainable as I have been looking to get some just to add to a box of potentially useful things to have. What twists are you typically using?

I don't think it would be that tough to neck down .30-30 brass to make it .28 caliber either.

Vall you are indeed correct Barry Darr built several 28 30-30's back in the 70's and his barrels were 14 Twist.

I've made .219 Zipper from 30-30 brass - didn't know it was hard to do - just did it.
