Two requirements

In order for the 22BRT to become more popular, two things would help. The first is a smaller flash hole to go along with the already small primer. This solution was easy. I just asked the manufacturer for it, and ordered 1000 cases with a PPC sized flash hole today (DONE). Second would be to offer finished cases that are already the 1.5" length and necked to 22 caliber. It's not out of the question, but not sure how many cases it would take. It could be a $10,000 dollar project. If this was to be done. It would be easier than the 6PPC. No necking or fireforming. Not to mention how much easier than the .100" - .125" short 22PPC. Please let me know if any of you are interested in this cartridge for short PPC capacity 22.

What's wrong with the ...

220 Russian as is or the 220 Beggs no-turn neck ??? Nothing to do but load'em and shoot. Art
 
Nothing

but I'm not into Russian, and the 220 isn't ideal capacity for a 22. The hot ticket is the shortened PPC in 22. As for no neck turn, not all are convinced that this is the way to go.

It is being made by Silver State Armory. The quality is nice. It also handles pressure well. I know everyone wants to stomp on any new idea that isn't PPC, but I haven't seen any major improvements in accuracy in 100 years when it comes to case design.

I just looked at their website

I see they have 6ppc brass too. They have br, non br and seconds. price isnt real good though. are they the ones that built the brass for graf when they did the 6ppc i wonder. Mike, have you sectioned the brass to look at the web and done any hardness tests versus the lapua 220. It is an interesting idea.

If it is the same quality as that Graf 6PPC Brass, it will not do for serious Benchrest work.
Plus, you also have tolook at the alloy, and the heat treat. Lapua seems to have a heads up on everyone else in the industry when it comes to this.......jackie
 
There is some information on the brass on 6mmBR.com. It was used by David Tubb in the 6XC. It was claimed to be harder and tougher than Lapua. The article said it was 6 points harder on the knupe scale than Lapua. I do know that from all test I have run on brass that was made to US military standards, that the velocities were much higher than any commercial brass such as Winchester, Remington, and Federal. I necked a full length 6.8 down to 6mm. A 58gr Vmax at 3953fps with a 24" barrel didn't loosen the primer. The factory seconds have the large flashhole. But the prices are much cheaper buying direct. Not sure if they did brass for Graf, but they did for Midway. I'm not saying that the quality is equal to Lapua, but hey, I've been using Winchester brass in my 30-30, which isn't near as nice of brass, but it is very competitve against the PPC. The PPC has been used with Sako, Norma, and now Lapua, and while the quality of the Lapua is far superior to the first two, it's agging ability doesn't seem to have changed much.

It is .418". It is a rimless 30-30. That is why you get short PPC capacity from a 1.5" length case. I just sectioned a 6.8 case and a 220 Russian case. I didn't have a Lapua 220 case though, so I sectioned a Sako. I will post the picture of the two side by side. If you didn't have Lapua brass, the 6.8 would have won easily. I actually thought the Sako case was kinda crappy. It gets very thin between the extractor groove and the inside bottom fillet radius (.050") versus the 6.8 at .090" thick. The 6.8 was noticeably harder than the Sako just judging from the mill vise markings in the case. I couldn't tighten the vise near a tight. It is very clear why Lapua is the best PPC brass available. The 6BR Lapua case sectioned on 6mmbr.com can be seen in the 6XC info page. This gives me an idea of the 220 Russian Lapua case.

Michael, what Sako brass did you section, the old original balloon head brass or the Sako USA brass? The standard load for the balloon head brass was 27.5 gr of 322. There is no way that it would handle the loads that some of the guys are shooting now days.

It has 220 Russian on the case head. It is not the USA brass. Maybe that's why it looked scary. I sure wouldn't shoot it at the pressures I run on the 6.8 brass or even my 30-30, much less the pressures run on Lapua brass.

Case web

Glad you guys aren't shooting this Sako brass nowdays. The 6BR Lapua resembles the 6.8 case web.
