Look what Santa Claus from Poetry, TX sent me for the project.
Exactly what is that? Are those 30-30 cases? Maybe 30-40 Krag. Why no headstamp? Who made them? What size primer? Details on the bolt please.

That's a bolt for a semi auto M-1 Garand, I think.
I went to the UPS Terminal shipping terminal, and not even they can ship it.
Here is the sign they have posted.

I thought it would be as simple as paying the HazMat fee
Sorry.

I have delivered the rifle to Nez. We put about 30 rounds through the gun, mainly seeing which powders would be the most usable to achieve velocities between 2700 fps and 2800 fps. The highest velocity achieved was 2876 fps. with AA2520 and 168 gr. Hybrids. That load resulted in a slight click on extraction, so I'm still thinking we just need to settle on 2800 fps. as maximum. At this point, we have achieved full 308 Winchester performance from a 30-30, so we were very pleased.
Now for the bolt design issue. When I received the rifle from Nez, it had been fitted with a 6.5-284 barrel. The barrel had the typical coned feed ramp that feeds so nice. The bolt had the matching angle on the lugs, but the angle stopped at bolt body diameter of .700", leaving a flat on the end of the bolt head. If you match the contour of the bolt head on the back of the barrel, it will be safe, but you lose the feed ramp, and defeat the whole purpose of a coned bolt. In this case, the cone shape had been cut all the way into the chamber. This left .203" of case head sticking out of the chamber, out of .210" total case head thickness. That's scary to me.
I re-machined the bolt head to bring the cone all the way into the bolt face diameter. By doing this, the case head is only sticking out about 137". I spoke with Mike Bryant about this matter, and he told me that he has had to deal with the same situation in the past. He also modifies the bolt head the same way I did for safety and maintaining a feed cone on the barrel. The gunsmith who had fit the 6.5-284 barrel is a well know shooter and gunsmith, so please choose your gunsmith wisely. Your life could depend on it. After the conversations I have had with Mike Bryant at the Cotton Ball match in Lubbock, over the phone, and seeing his work in person, I highly recommend his work. I have attached photos and drawings.

Can someone explain to me what is to be gained by using a 30-30 case to push a 168 at 27-2800 for 600 yds? When you can run a 110 SMK at 2900+ out of a 6br Imp. both bullets have the same BC.and at 600 the conditions have a greater affect on them than raw accuracy but the 110 is shooting in the low .1's @ 100..... jim

Jim,
I was quite in a hurry when I responded. The 6MMs have shown some impressive performances in the line. Along with the 6.5s, they are a dominant force on the 600 yard line. However, when you put a sling on and shoot on your elbow, the game changes. Here is an example, Stacey is a multiple range record holder at Bayou Rifles with his bolt gun, a 6mm with unlimited power scope, but a lowly 223 shooter, with 20 inch barrel, 4.5X scope took him to a good match. In fact out Xed him. Remember the .224 bullets are nowhere near the BC of the 6s.

Back to the 30-30. Michael managed to showcase the capability of the 30-30 in short range stool shooting in both group and score shooting. His successes with the 30-30 inspired me to have him build me one. I don't have the know how nor the correct reamer for the 30-30, Michael does, so I asked him if he were interested in doing my project. I am glad he did. Now, if I could even get close (even twice or three times as large) to the group he shot with his 30-30 in testing, I would be happy to shoot it either sling or F Class.
At the end of the day, you know the saying about the Indian and his arrow.....
Chuckle chuckle, you will have a load of fun with it Nez!
