I don’t use titewad. It’s so fine and fluffy in the Arizona dry it sticks to everything and doesn’t meter well. Clays, Bullseye and Green dot for all fiber.

I use Titewad when I reload. It can get static-cy and messing if you're not careful. I think we discussed that on here not too long ago.

Go to Natchez shooting supply:

They have on sale B & P Comp 1 in 7/8 oz. for 10 bucks right now in 12g. The psi is between 5,000 and 6,000 and should work for any old gun if the barrels are in good shape.

This has been mentioned before but it bears repeating it is a safety issue:
According to Tom Armbrust, any reported pressure testing of 2" shells that were tested in longer chambers doesn't reflect true pressure in a 2" chamber. Boyle's law at work. I only know of one tester that has 2" chambers for testing and that is Big Bore Ballistics which is located in Ft. Valley, GA. If there are more, I am curious. There are some modern 2" chambered guns that were made to be compliant with modern standards, either European or American. The 1930's English guns weren't. Last year there was a long thread on this subject and it is a shame that Mr. Ed, the talking horse, died while being beat to death over this issue. I was in there swinging, too.
Published pressures by commercial shell manufacturers may only be accurate for that flat of shells tested and are no guarantees that the following run will have the same pressures as companies are controlled by SAAMI limits and companies will often load to that limit if that's what the components used will yield. Components may vary in a particular brand which can mean pressures can vary but will always be below SAAMI. RST is the exception. If it says low pressure, it is low pressure. At least one of the well known testers refuses to test factory ammo because of the year to year or run to run variation. Probably a matter of liability protection for the testers. Gil

A sleeved gun is not a monobloc gun. A monobloc gun is not a sleeved gun.

They are different.

The mini shells are not 2”, and this marks the first time I have seen 2” ammunition, an obscure English 12 gauge loading, not of commercial significance, confused with the 1 3/4”tactical mini shells

As has been pointed out already, the Federal 1 3/4” loads are not loaded as low pressure ammunition, and I highly doubt that batch-to-batch testing of same would yield consistent pressure levels of 9500psi. They would likely float between 9500psi and SAAMI max. It is unrealistic to expect that ammunition produced with globally sourced components will have consistent lot-to-lot pressure values. You have one fact when dealing with commercial consumer shotgun ammunition loaded for the US market-it will be loaded at or below SAAMI max. If it isn’t stated on the product, you can assume SAAMI max.

I found 2 more images from Toby Barclay's sleeving tutorial. Note the sleeve extends the full length of the chamber



'SLEEVED' on the breech



In contrast the monobloc used by almost every Italian maker, and Browning, today; and different from the Beretta 1903 patent



Oops

The pictures make the whole process a lot clearer to me. For those wondering, this gun was proofed after sleeving at 3 tons. I’m very grateful for the responses. I had read on another forum that those mini shells were reportedly low pressure, but the consensus here seems to be no, and I tend to believe the folks here know of what they speak. The B&P shells seem to me to be the ticket, despite them being 2-3/4” length. At the stated pressures, it appears I can afford a spike even in excess of Mr. Bell’s findings without too much worry.

Most guys I know with 2 1/2” guns reload low pressure loads in a 2 3/4” case.

Best,
Ted

the useful fact to remember here, stateside, is that the majority of shells are being sold for use in pump guns - and autoloaders. the pump guns are okay (generally speaking) with all ammo....low pressure or high. but, many autoloaders are gas operated, and require some minimum chamber pressure level to function the action.

those of us here, who fancy old doubles are not a significant market force - and unless the pressure level of shells is clearly indicated as being appropriate for our uses....it is best to assume that all ammunition sold here is tailored to make sure that gas operated autos will cycle.

would be good to be somewhere that low pressure stuff is marketed generally.

Thanks for the heads up builder. I just ordered 2 flats of B&P. I've been looking for Winchester Low Recoil-Low Noise loads since June at the local stores with no luck.
