I took advantage of Cabelas sale in Pedersoli Gibbs. I have wanted one for several years. So far I have put 50 rds thru it. It is as accurate as I have heard it's supposed to be. Fit and finish is good and it has decent wood. I started at 100 yds using cast bullets from the 535 gr mold that actually cast a 520 gr bullet. I had to size bullets down to .450---.449 would be a little easier to load. With 85 grs of Goex Cartridge it trys to shoot a ragged hole. Today I shot some RCE PP bullets that weigh 530 grs sized .448--they were a perfect fit for the bore. Same accuracy--groups around an inch at 100 yds. I tried loads with and without a dry wool felt wad--it shot better with the wad. If anyone ever thought about buying one, I reccomend it highly. Does anyone have any feedback on shooting a Gibbs?

The Gibbs has done a great job of opening up long range shooting to a whole new bunch of shooters. It has a good reputation for accuracy. There were many on the firing point at the recent World Long Range Championships.

Sir, what alloy (or straight lead) are you using?
So far I have only used pure lead in both PP and cast bullets. I have some 20-1 made up but have not tried them. Paul are you using pure lead or an alloy? On the use of platinum lined nipples---why do you think the Gibbs has higher breech pressure, do you really think the standard nipples burn out in 30-50 rds? I don't see this problem in other rifles that use slugs or conicals with large charges.

I don't know about platinum lined nipples, but I believe that the Gibbs (like my Mortimer Whitworth, same twist bore and bullet) comes with a beryllium nipple, which is supposed to last a lot longer than the standard.
Should be a great gun!

If you talk to the bullet shooters- the slug gun shooters in particular-- they can teach you all kinds of things about choosing nipples, nipple life in these guns, and variations in erosion based on caliber, and powder used.

You can get .448 and .449 sizer dies, and platinum nipples along with a ton of long range things from J. CUNARD & company. The only problem is Joe is VERY sick. I ordered a .448 sizer dies a couple of days ago and he said he would try. He sounded very sick I hope he is doing better. Ron

That is the problem with this sport. There are so few people providing parts that when one of them gets sick, or dies, the entire sport loses, and it can take years before someone else begins supplying the parts no longer being made by that lost person. I don't have THE answer to this chronic problem, but I have some ideas that we shooters should explore as a group.
In Japan, for instance the government has a program that supports "Living Treasures", where they identify artists and artisans, or craftsmen and women who happen to keep traditional arts and crafts form and methods alive. These people are given a monthly stipend, on the condition that they train younger people in the skills they have, so that the art or craft is carried on after they are gone. The students are selected by the master, but the government supports them, too.
I don't think MLing is big enough to raise the kinds of money needed to support master craftsmen, and their students, in all skills, but we might be able to create a scholarship fund to pay masters to teach students their skills, with the idea that the student is obligated to carry on the skill after the master is no longer able to do so, regardless the reason. Being America, the program would have to be voluntary, of course, and I don't WANT the government involved in it AT ALL. But, I am sure the NMLRA would be interested in overseeing this kind of scholarship program for the benefit of us all. It would fit into, and extend, Its current educational training program quite well.

Long range match rifles firing charges in the region of 90-100 grain charges with 500-560 grain bullets develop high breech pressures. The pressure and temperatures developed can result in gas cutting of the nipple. Platinum was used in the nineteenth century to minimise this gas cutting. As the flash hole enlarges the hammer may be slightly lifted leading to pressure loss and consequent loss of accuracy.
These small variations in pressure may not show at short range, but at long range can be significant.
Jeff Tanner in the UK will line your nipple. See the Accessories section of his web site:

I've been using one for at least 3 years and it's still fine.

Z...David speaks the truth about platinum nipples. I used the beryllium nipple that came with the gun. Accuracy was very good for the first couple of hundred shots but accuracy seemed to fall off. Switched to a platinum lined nipple and groups tightened up again. I use 24:1 at present but intend to try 20:1 as soon as I can. Breech pressure is high due to big powder charges and big bullets. Use a greased bullet or paper patched bullet that is as close to bore diameter as you can get and still have it load easily. If you can, try your Gibbs out at 200 or more yards...that's when the fun really starts! Good luck and keep us posted. Paul
Z...I had the same problem with hang/misfires. I made sure that I wasn't using too much liquid on my patches when cleaning between shots. Damp patch good---wet patch BAD. I was using regular cci caps. When I switched to cci mag caps the problem was almost eliminated. When I switched to RWS mag caps the problem WAS eliminated. Seemed like a hot cap was what my rifle liked to make things go bang on demand. cheers Paul
