Eezox for both lube and bore cleaner. https://www.amazon.com/Eezox-Premium-Synthetic-Gun-Care/dp/B07FCRVTDL

Probably different chamber dimensions. Take a magic marker and from the butter to the rim, run a line on both sides of the round. See where the round is scraping off the ink. Good guess you will have to resize the case with a full length sizing die. Remove the decamping pin, lube the case and resize them down to the web on the case just above the rim. I’ve this issue with new and used brass. A larger web squeezes down resolved the chambering issue. Good Luck

Lawman, 45 Colt's are 452. Why do you need 453 or 453 bullets?

Try Stetson hats on eBay.... https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l2632.R2.TR12.TRC2.A0.H1.Xstetson+hats.TRS0&_nkw=stetson+hats&_sacat=4250

Meade Scopes, pick one ... https://www.meade.com/binoculars-spotting-scopes/spotting-scopes.html I've been using an older model 20x60x60 for about 5 years. 45-70 holes at 600yds on paper and lead splashes on steel at 1000yds You'll need a scope stand also for either bench or long range spotting ... they can be expensive

The standard load for a 410 is this . Your talking about a 12ga .410 25 grains 3/8 2 inch shell

Let's go further too .. A standard 12-gauge slug normally weighs an ounce, and comes out of the muzzle at around 1,650 fps. Your 775gr (1.75oz) slug for a standard BP charge equates to 95grs of powder. I don't believe this powder charge will be safe in your shotgun plus have you tried putting the charge - wad and slug in the case? And the felt recoil is going to be severely uncomfortable

Yes, you are so off base with your black powder charge of 10grs ....it is pathetic. For a 1 1/8 charge of shot in a 12ga hull, I use 85grs of Fg powder. You might want to read this website in detail ... http://www.tbullock.com/bpsg.html

IMO another gizmo putting reloads in and taking them out. Split cases are easily determined at the priming stage. High primers? Use the Lee Auto Primer and any case with a high primer cannot be removed from the tool .... Done

Yep, it happens with those rebounding hammers on single trigger SxS's Has happened with me shooting full drams of black powder

Hand Book ... Single Shot and Buffalo Single Shot firearms must be originals or replicas of single shot rifles manufactured during the period from approximately 1860 until 1899. Remington 7mm models, 1901 and 1902, years of production ... 1897/02/10 Therefore Yes for Single Shot Side Match(Long Range) if a Model 1 Many Rolling Block rifles were used by Argentina before being replaced in 1891 by the new 7.65mm Mauser, and were also widely used by Egypt and Mexico. Candidly though, doubt if any Match Director would know the difference between a Model 1 or Model 2

I vaguely Big Ed was going to produce just saddles after the sad series of family issues and no help making rigs. But there is no website for him Call Spangenberg Gun Shop in Tombstone... (520) 457-9229 They should know yes or no if he is still in business and where He sure made great holsters

KId, what's the issue with the 500 that you need a 'specialist' gunsmith to work on it?

Ruff, I am a Lee Factory Crimp die user but based on your reply I'll order a Redding and give it a try ... Thanks
