Excellent results! That Blackhawk group was phenomenal.

[@thealsatian4232]

That’s a great bullet. One of my favorites.

[@JWheeler331]

Not a bad group with the Blackhawk.

[@paladin4570]

Great video. Shoots great out of the Blackhawk and seemed to feed good out of the Marlin. I’m anxious to see you shoot your pet loads through the Blackhawk to see if it tightened up. I’d bet it is better with the 11 degree forcing cone. I need to by a FC reamer. Keep up the great videos. Excellent content.

[@ZzKaNg0zZ]

Way to go on making that a better shooter

[@ChristianGrest]

Awesome groups my man! Looks like a winner in my book.

[@paladin4570]

With all the great modifications you have made recently, one I’ve done several times is to swap the Blackhawk hammer for a Super Blackhawk hammer. It’s lower, wider and best of all drops in. The Bisley hammer looks awesome but, requires some machining in the frame for it to fit in and work. Again, great video.

Thanks for the advice! I also appreciate the kind words!

Hey Brother thanks for bringing us along on this journey. Load some of your old loads and see the difference? I definitely follow all those fellas. Just got the Xero chronograph from Brownells this is the piece I’ve been missing. Just wanted to give a like and comment for the algorithm. 5keverydayedc

Keep up the good work! I’ve been enjoying watching this journey with your Blackhawk in .45 colt. Your videos are great!

[@j_c_hunt]

Thank you very much! I appreciate the kind words and encouragement.

[@GregsGruns]

Interesting that those are .452” for some reason I was under the impression that .45 Colt used a .454” bullet. I loaded some .452” .45 Colt long ago when I didn’t know what I was doing and they weren’t very accurate lol

[@gabehanratty4783]

Pre WW2 guns are mostly .454. Ruger makes all their guns .452

[@BlakeHouse-j3u]

That's the standard folklore anyway , with a bit of truth to it . What's most important is matching the bullet diameter to the Throat diameter .

[@Wireman134]

@@gabehanratty4783 Actually the Ruger barrels are .451" A .452" boolit and .452" cylinder throats is what you need.

[@keithhartman9946]

"If it works at all" Was that a little jab at Remlin? Lol

[@thealsatian4232]

It’s not a copy of the 270SAA but it’s better because it the 270SAA will give chambering difficulties in a Freedom Arms .45 Colt chamber. This one will chamber just fine. Try them over 8 gr Unique for a powerful load that is safe in a SAA

[@j_c_hunt]

Will do! Thanks for the advice and information!

Spam n eggs and a favorite show.

My .45 Colt Blackhawk info in the box says to sight it at the 6:00 position. I’m still trying to figure out where to point it. I guess I’ll have to do what you did to the Blackhawk. I’ll have to take it to my gunsmith to have it done. Plowboy explained his way of reaming out the throat of the cylinder but I’m not going to take a chance of screwing it up. As far as the forcing cone maybe you can tell me what the significance is of doing that. I appreciate your info and video brother!!! Maybe you explained it so I’ll rewatch your video. Thanks again!!

[@carycary5824]

My Henry .45 colt isn’t grouping like I’d like it either. It’s probably the ammo. I’m a fair shot with a rifle but my eyes are getting older so it may be me too. Thanks!

[@dinsixiengmay9781]

Funny and perfect timing I just order 500rds of those rim rock 45 colt cast bullets👍

[@keithhartman9946]

I'm curious as why you changed the degree on the forcing cone. Seems like it would lessen velocity

[@j_c_hunt]

Rugers come with a 5* cone. Changing to an 11* cone improves accuracy with the gentler slope guiding the bullet into the barrel, especially with cast bullets.

[@keithhartman9946]

@j_c_hunt thanks for the info I know colt has generally used large forcing cones and gaps to the detriment of velocity. I love my dan Wessons in part because of the ability to adjust gap. My most accurate handguns for sure.

[@jesseboutdoors]

Good testing 👍🇺🇸

[@bigtrucklittlerv7969]

The Lee 300RF offers so much more than this SWC

[@Wireman134]

Yep, I modified the Lee C452-300RF mold removing the rebated base making it a plain base boolit weighing around 310gr using my alloy. Water dropped to 15 bhn. 19 gr 2400 is also good with this boolit.

[@larryalexander4833]

I have Ruger bisley 45 I need to get the forcing cone worked on. How much does the tools cost ? I have already changed my cylinder pin and reamed the cylinder throats myself.

[@j_c_hunt]

Brownells listed the set for 38-45 as out of stock. They do however list each individual piece in stock, so I got them that way. Ran about a hundred bucks for the tapered ream, bushings, rod, and T handle. A plug gauge runs about another 50ish.
