That's a real tough one, Don. It's something I hadn't even considered but, should have thought about, considering that it's a caliber limited class of "Elite" shooting

In the day that 28 calibers where used in Schuetzen, bore and grooves were not tightly controlled. As a nominal standard, I would say that a .280 bore and a .288 groove would be about maximum. Most people building rifles, will use 7mm barrel, of .276 bore and .284 groove. So, using logic, we could give a +/- .004 tolerance (.284/.288) and and say maximum could be .292 and your only .002 from that is if, your .294 is your groove diameter.

Before I give a diffident answer, I'd like to hear form owners of original 28/30 rifles, what their groove diameters are and I'd also like to hear from the people that have shot their T-28's since this class started.

I just thought to look at the Lyman/Ideal, as cast mold sizes and this is a picture of the listings for 7mm/28 caliber. first colum is mold #, second as cast, thrid number is as cast for a mold marked "U", last number is the nose punch. .290 is the largest as cast mold.

CW for competition I would go for a heaver bullet if your twist can support it. In my 12 twist I am using a 147gr. Mos., 155gr. Darr Truncated and a 145gr. of my own design and making. I have also shot the 134gr. Hoch as sold by CPA for the 14 twist but I do prefer the extra weight and these are all being shot breech seated.

I hope this might be helpful it is a fun caliber to compete with and I wish you the best.

John. a pic of the 28-35SS Brass ?  I found some of my original formings 25-35 original, half fireformed and full blown. Will get a pic later. Pete

Here are your pictures Pete.

Just to show the difference between the two here's a factory 25-35 Winchester on the left, with a 28-35SS on the right.

Thanks Jerry_H my picture was not as clear of what it actually is compared to yours.

Thanks Again!

It's a work in progress. I set my 28-30 Stevens chambered barrel back 1.50" to get rid of the shank as it was too small for the FBW Model J action. The 28-35SS reamer cleaned up what was left of the chamber.

The buttstock still has some final shaping that needs to be done but it's getting closer. The buttstock and forearm are from the same piece of walnut even though they don't look like it. The forearm has more handling and time to oxidize than the buttstock so they should turn out the same eventually. I'll be using Alkanet Root to dye the wood with an oil finish over that. 

I added a horn grip cap because I thought it would look right after checking out vintage Schuetzen rifle pictures. The buttplate is a Barry Darr white bronze casting from an original Zischang buttplate.

I like vintage/traditional looking Schuetzen rifles so I tried my best to capture that look with this rifle. I'm an amateur, at best, when it comes to building rifles, but I sure do have fun trying.

Rifle looks good from here Jerry. 

Hoe long is 28-35 case after blowing it out?
