I am surprised the firing pin is so much smaller then the hole. You have the correct 0.065 firing pin, I don't have a HP bolt laying around to measure but 0.083 sounds like the bolt for a standard pressure pin. Big hole will cause problems. What do the primers look like after firing?

One thing about the less expensive bits, the shank is undersized compared to the hole called out or drilled, so once you find a snug fit you need to measure with the digital or dial caliper. Then order quality bits next sizes up. my bet you will end up running wit a 48, 47, or 2mm. If you are patient you could start small and test each size.

I like the cobalt as well, stay sharp longer, but maybe just a little more brittle. Just go easy. Some barrels have a hard outer coating as well as the bore. you can slide a wood dowel in the barrel if you prefer for punch through. I have bought Maxtool, Uxcell, topline cobalt's off amazon all good. I have a mill so it is real easy, but most of the brothers here use a cordless drill with success.

Have you shot it with current configuration? The 0.077 would be close, I used the numbered bit that equates to 0.079 (don't remember which one that is) on 3 different .308's, one with Carbine Gas / 18" barrel and the other 2 with 12-1/2" barrels and different custom length gas tubes. All 3 have AGB's but run close to all the way open. Ran one with 7" buffer tube and short buffer / tailhook tube. Orange spring. Another option would be to get a numbered set of bits, and sneak up on the correct size with a fixed AGB, more range trips but eliminate the AGB. I would also get an orange sprinco spring if it was me running the short buffer.

Vortex was good about replacing a crossfire for me. It is their entry level line, and is easier to damage apparently. on mine the culprit was over tightened rings. Bought used.

I've done a couple 40's, brothers have done a 40 and a 45, now a 10. Thinking 10mm is about on the edge for blowbacks without delay.

Haven't shot it yet, maybe next weekend.

Length with the BCG came out about 1/8" behind the bolt catch, about right no quarters. Maybe get out to the range next weekend see if it actually works. May need some tuning of the buffer and spring. Should be close. Cerakote Graphite black over gold

Limited experience, but had to drill up a 308 and a 6.5 Creedmore BA. Post the port diameter when the barrel shows up. Numbered drill bit set is ideal for determining size of port. I would expect around 0.079 would run about right with your setup, lots of experts here so might get some other advice on that. Also watch for gas tubes, 12-1/16" (Large frame carbine) is usually correct, 11-3/4" (ar15 midlength) usually a little short. But not always. Both the 6.5 and the 308 BA's I messed with took 12-1/16" Gas tube should hit center of cam cut out. This is a 12-1/16 in an Anderson AM10 Carbine. Just right. Came with a 11-3/4"

Actually Ramen

No ramen, but quick shipping and 7-11/16" +/- internal depth extension.

I have the old Dillon RT1200 power head trimmer for the 650, flies through them but they need a little case lube on them. Die is almost as tight as a sizing die, maybe to prevent chatter. Set up for 308, 223, 338, 44. Can run sizing/ deprime operation in the first station at the same time. Don't like using the case feeder with the imperial wax on the larger cases, picks up dirt, but the one shot works on the 223 in the feeder.

Ramen is OK.

Hey, All Anyone done any business with Rooftop Defense? https://www.rooftopdefense.com/ Need a 7-11/16 extension, they have them and will ship to WA, where as no one else with them in stock will. I gotta get outa this place... Thanks-- Al

Some good pointers.

I like the 3x magnifier combos on AR's Like peas and carrots...

In the larger calibers, huge volume swing between brands. Amounting to 80-90 FPS in the 300 Weatherby between Weatherby brass and R-P Brass with identical charges. With my 338, I've had it so long that my brass is all over the place. Trying to keep batches together, have a Redding die that controls length and have a Dillon trimmer for the 650 when they get way out of control.

Flash hole deburring tool is one of the best "Bang for the Buck" reloading tools out there. Rifle I like to see 10 or less, 5 or less is outstanding. Your last line is looking good. There are arguments on whether (and how) a low SD relates to a tight group, but the way I see it it can't hurt and is good feedback on the quality of the handload.

Yea, didn't last long, a guy just posted a nice shooter over on waguns...

The Uberti Cattleman 44 showed up. Beautiful sixshooter. 1873 cap n ball, replica of a gun that didn't exist. One more in the mail, a 1851 Engraved Navy, no more bids out after that.

The one in the middle is a F.Lli Pietta, steel frame, a lot stronger then the brass frame models which in my case are Armi San Marcos but everyone made both types, ASM, Pietta, Uberti, etc. The Piettas are metric threads and the cylinders are a few thousands longer, and so far seems like the Uberti's and the ASM's are all US threading and pretty much interchangeable although Uberti's are a higher quality and the cylinder, although interchangeable with the ASM, are a couple thousands smaller diameter. Supposedly brass frames became popular because both sides were running out of steel, south in the worse shape. Looking closely at the brass frame models when they start to stretch a gap will open up here. Like this one

Like to get a shoulder stock for the buffalo. Seeing how there are no regulations on BPSBR's
