Are Short Action Custom (SAC) bushings the bomb?

[fatelvis]

After watching my favorite YouTube guy "Johnny's Reloading Bench's" episode about the "best" bushings

He found that SAC bushings actually do produce loads with less runout. Can anybody confirm this? Did I just waste HUNDREDS of dollars on Redding bushings, just to find this out? Lol
Looking at SAC's website, the cost is comparable. I think I'll be buying them from now on.....

I'd run a test of Redding vs SAC bushings. Shoot a few comparison groups to see if it matters on target.

 

[fatelvis]

I found it strange, and really can't figure out why, the SAC bushing he used was .001" larger than the Redding bushing, but they both sized the neck down to the same o.d. on the neck. He checked the i.d. of both bushings using pin gauges, and they were marked correctly. Hmmm

I'd say that you did not waste your money. Redding bushings have certainly been used by a LOT of shooters over the years, with excellent results. You got what you paid for and they should work just fine.

I'd be surprised if the bushing itself is the primary cause of excessive runout in the majority of cases. For that reason, it's difficult for me to comprehend how a different brand of bushings would have a noticeable effect on runout in a properly set up sizing die. Having said that, I'd be interested to find out whether Mark Gordon's bushings are "truer" to the stated size than other brands. In my hands, a specific sized Redding bushing may get you close, but the actual OD of sized necks may not always be the OD expected from a given bushing.

Sac bushings aint got nothin on micron bushings or the carbide ones benchrite sells

Could the tapered entry impact springback?

Dusty, do you agree with the premise of the video that a high end bushing will reduce runout?

No. Unless your low end bushing really sucks. Ive never had a bad redding bushing but i have had bad dies

 

[Dusty Stevens]

I actually prefer the whidden bushings myself. They seem to be the best for me in cost vs quality. I have a bunch of all the brands though

 

[JMayo]

I would think the die being correct where the bushing goes is where the runout comes from. Idk
Or I must just be lucky. My brass has very very little runout. I have Wilson and rcbs bushings. 30br, 6bra, 6ppc

I like the Benchrite carbide bushings

If all bushings exhibit zero runout on the ID and OD, how would one induce more runout?

SAC claims that all OTHER bushings are inferior because they are basically cylinder shaped inside, where theirs is tapered at the end, and that “supposedly”induces less runout. (If I understand that correctly)

I like my bushings to be straight. I let my straight bushings, concentric necks and good dies determine my runout

Another lame attempt to make something out of nothing. If it is round and too size I really don't care what brand it is.

It's only another 35 to 40 bucks to find out. At this point after spending thousands, what's another 40 bucks?

What I see here are opinions with no facts, or experience.

It is possible that the hole might not be coaxial with the outer cylinder walls.

 

[LRPV]

The hole might be egg shaped, or the surfaces on the top and/or bottom are not square with the hole. The hole may measure .260 even though it’s marked .262 or vice versa. There are many ways to mess up something as simple as a bushing.

 

[jimmymac]

I just bought a SAC bushing. First thing I did was measure the length for deck height variation. One side is .001 longer than the other.

Haven’t tried it yet, but I know from the get go there is at least one dimension that is out of kilter. Might not make any difference, but then again…
