Nope! but we'll find out after load development do we. I shoot with a couple of guys at our 1K match with same chambering on a Remmy action, and they're just doing fine without bushing the firing pin. They recommend the use of CCI BR primer however which currently I don't have. I have a bunch of Federal Match and Remingtons. I do however has a couple hundred of older Federal Magnum small primer that's no longer made. I use those with my 222 Remington Magnum.

The barrel is 26 inches without the brake. I have Berger 130 or 140 in mind stoke with Reloader 15 or H4350.For scope however... probably a Nightforce NSX or a Vortex Razor, although I don't mind another MK-4 with TMR, just like in my 338 Lapua. After all, I really like the TMR reticle.

Cool thanks, keep me updated if you bush the firing pin. I'm eye balling my tikka for the caliber, should work good with the tikka mag.

I'll probably change bolt before I bushed the firing pin.

Checking max seating depth to fit the AICS magazine using the 308 case as guide. Don't have a 6.5-47 case yet. The 308 is a tad longer than the 6.5-47. The bullet from top to bottom are Sierra 140, 142 and Berger 140. Looks like I have enough room for 40 grains of H4350.DSC01912.jpg

Tell use about that cartridge and why it's so good for long range shooting.It's hard to keep up with all these new rounds.That is a very nice rifle I like it.

A combination of moderate recoil, high ballistic coefficient bullet, longer barrel life makes it a perfect cartridge for competition where hundred of rounds can be fired in a single day.

I was looking at building one of those when I decided on the 260
You can't go wrong with either one. The performance is almost identical. As a matter of fact I was contemplating on having a 260 Ackley before deciding on the 47.

For a mountain rifle, I will opt for either a 260 or a 6.5-284 to get that extra 'umph. As a matter of fact, I built one in 6.5-284 for that purpose. It's on the heavy side for a mountain rifle, about 9 pounds, but compared to most of my rifle I logged around, it's a lightweight. Texas2010010.jpg

I'm worried that the 56" objective of the Nightforce would be too big for Gruning mounting system so I borrowed my buddy Franks brand new scope and mounted it in my rifle to check if there's enough clearance. The scope fits perfectly and it looks good on rifle. So I called my buddy Frank to inform him that the scope got stuck on the rifle and it won't come out. :blink:DSC01913.jpgDSC01914.jpgDSC01917.jpgDSC01922.jpg

Went to the range late this afternoon. I had one hour of day light left to shoot so no time to even set up the chrono. I loaded the 130 grain Berger VLD using IMR 4350 and Remington 7-1/2 Small Match primer. I can't find H4350 locally so I had to choose between Reloader 15 and the IMR 4350. I have both powder in my inventory. I choose the 4350 because it's a much slower powder than the 15. I loaded 25 round, 5 each starting at 37, 37.5, 38, 38.5 and 39 grain. I seated the bullet .05" off the land. DSC01924.jpgI wasted all 5 of the cartridge loaded with 37 just zeroing the rifle. I made a mistake on slapping the IOR from my 308 into the 6.5 without collimating the scope first. I should have known better. I already wasted 3 rounds when I realized that the scope was way -off.I can see slight extractor marks on the fired case although barely noticeable. Extraction was fine however. I was ready to packed it in but out of curiosity, I decided to try the load with 37.5 grain of powder. It's really getting dark and I could barely see the small red dot on the 6" Shoot N C target at 110 yards. I fired the first shot and I immediately noticed that the bullet landed about an inch low right at the target. I proceeded and fired two more shot but I can't see no other hole. I went to retrieved the target and saw that all three 130 grain Berger made one small ragged hole. Here's the picture of the 3 shot group at 110 yards.IMG_0218.jpgIMG_0219.jpgI need to start below 37 grain and work up to the desired velocity. This combination is fine! All it need is a little tweaking.

Nice rifle and shooting. I would be real happy with a one hole group first time out. Congrats on your new rifle.

Thanks Bennie. This is the kind of accuracy you can expect from a Gruning Rifle. Finding load won't be a problem either. Just put together what you have and the rifle will shoot just fine.

I don't have much experienced with heavier 6MM bullet... don't own target rifle chambered in 6MM either. I think Fjold here shoots the 243.
