The LnL bushing system is very convenient. I put a witness mark on my bushings and one on the press to make sure it’s in the same lugs every time. I haven’t tested it to see if it makes a difference, but with it in the same orientation every time, it’s consistent.
I have been using the same setup on rock chucker for 7 years with no problems. Every single die in my collection has that bushing so once I have done final adjustments it stays there forever. Now, put a die in the press is a 5 sec deal.
A little heads up on split type lock rings, if the screw is completely loose when you tighten the lock ring against the lock and load adapter, and you tighten the lock ring screw very tight, you will never accidentally loosen the lock ring on the adapter. BTW I have had one of these conversions on my Rock Chucker for years.
Hi, I would really value your opinion regarding RCBS Rebel, RCBS Summit, & Forster CO-AX? Which would you choose for accuracy ie concentricity. Thanks for all the great videos.
Good morning. Have you taken the opportunity to verify the repeatability of something as precise as bullet seating or shoulder bump? I think the idea of the bushings is good but unsure of the locking lug consistency. What do think?
Hi John - Where did you find the Limited Edition Summit Press? Your first video was only a couple days ago, so I went to the RCBS web site and they don't even show this painted version.
Are we confident in the accuracy of the machining of these inexpensive bits and pieces?… are they axially true and concentrically centered to a tight tolerance?… how much does that even matter? Would you trust these for FL bump sizing brass, mandrelling necks and seating bullets for competition?
Great review John, I was just looking at my rcbs press this morning and thought if I unscrew this piece it would be great to have a conversion to lock and load or the Lee breach lock 😂
I went the opposite direction, I had a Hornady LNL press, was starting to get movement in the bushing when sizing, to me any movement in your die is not good, I removed the LNL adapter and installed a normal Lee insert, eventually went with RCBS
If you find them lock and load bushings loosening up on you they have an o-ring on there. You can actually get a bigger o-ring and it should fix it. The other way is to call Hornady. They have a special shim kit to help you tighten up those lock and load rings
With my lock-n-load bushings on my hornady press there is a lot of movement with the bushings so I feel like you'd lose some precision converting this.
John, I've seen some evidence that these cause consistency issues when sizing brass. I'd love to see an indicator put on top of a die while sizing brass. I'm just too skeptical of them at this time. Thanks for another great video!
I've been using them for years, have not had issues. I clean, anneal with amp, and size. I achieve consistent .002 shoulder bump over and over. Your concerns are not unwarranted though, I get what you mean. It introduces tolerance play. But it works for me so far. If you had an extra press just or decapping or mandrel work it would be worth it just for that.
If you can't get a wrench on the insert to tighten it in the press and are using the LnL bushing and die to tighten the insert, how do you remove the insert should you wish to do so?
@@awcmon123 I would have thought the LnL bushing would cam out of the insert before it could have enough torque to loosen it. I've not used those bushings so......... Thanks
@@josephjulian2503 It unlocks, but it does not come out with rotation, so you can just keep torquing. It might be a bit hard to explain, so looking at how the bushing is designed will probably be more helpful. It sorta just drops in, then rotation either locks or unlocks it, and no more.
Maybe someone has a fix. I use these, but fin that they tend to work themselves loose every 25-50 rounds or so. The quick lock moves counter clockwise enough to give 1-2 thou change in headspace. Any thoughts or suggestions are welcome.
Depends on how many cartridges you need to add them to, they aren't expensive, but, do add up. Never found a real need for them, I do the bulk of my stuff on a Co-Ax.
The Hornady system not clamping to the die has the benefit of being able to have free floating dies if you use Armamov's LnL bushings and lock rings at least. Probably not too useful for your use case, but I've come to appreciate it since I use a Rock Chucker as my primary precision loading press. The Armamov bushings even come with wrench flats, so you can torque that instead of the die. Hornady seriously needs to just include wrench flats on the main bushing though.
I thought he armanovs only work with their t7 toolhead. Do these really work with the rock chucker? I seem to recall that they allow the rings to lock in place like on the armanov dillon heads

Converted my RCBS single a looong time ago.
Hi, I would really value your opinion regarding RCBS Rebel, RCBS Summit, & Forster CO-AX? Which would you choose for accuracy ie concentricity. Thanks for all the great videos.
I took one of the quick change bushings and cut flats on both sides so I can easily just wrench it in. Works great.
Yeah that's a good idea.

LEE has one also, that's the one I used to convert my summit

There’s a link in the description.

I like the Lee's bushing setup way more than the LNL ones

Same here - would love to hear from John or anyone else who has been using them for a while.

Same way it was installed. Put a die in and twist the other way. Hornady really needs to add wrench flats though.

amazon has a 10pack and I'd think with the 6pack conversion kit it would cover most folks. 16 for about $100, works for me.

@@wathaet1386 Armamov makes their own free float LnL bushings that work in anything that takes LnL bushings.
Very Interesting John , Thank you , 💯💥💥💥💥💥💥💥

Why do my comments keep getting deleted...I'm trying to f****** help here!
No idea, it ain't me.
Why add this ? It's not hard at all or time consuming to screw a die into the press.
