Detailed Description

Super Crown Crimp Starter: Large Bore 8-point 

Our Super Crown Crimp Starter is legendary. We've been making the finest crimp starter in the business for over 35 years. It is the ultimate crimp accessory for your MEC reloader and it solves the problem of getting a good, deep crimp start on new hulls.

Why brass? Machined from solid brass, the Super Crown's sharp edges make a deep impression in the hull's crimp folds. Yes, solid brass is an expensive material, but we use brass because that is what commercial loading machines use to create those reliable, deeply-folded crimps. Even unskived and new plastic hulls are easily creased for proper crimps once they go through any MEC crimp starter station equipped with the Super Crown. Easy to install and fits all MEC machines. Comes complete with wingnut hardware and crimp accommodation spring.

We machine these quality tools right here in Minnesota.

Super Crown crimp starters are available in four variations:

Crimping tips: 
Six-point crimps are mainly used for larger pellets/hunting loads. 10 gauge and 12 gauge 3-1/2" and 3" are almost always six-point crimps. Because there are less folds involved with a 6-point crimp, it is generally easier to crimp hulls with in this manner

Eight-point crimps
are generally for smaller pellets, which is why you always see target loads with 8-point crimps. The Super Crown produces deep and crisp edges, which will aid in closing up gaps. This tool helps to produce tighter, more consistent crimps.

Too sharp? It's possible to cut some types of hull materials, but this is rare. Remember, we manufacture the Super Crown with a sharp edge because that's what puts a deep memory in the crimp. It's easy to dull the edges a bit with a little emery cloth or fine-grit sandpaper. Just be careful when you are doing this. 

Also Recommended:

Installation Notes: Remove stock plastic crimp starter and mounting bolt. Install Super Crown and adjust depth with locking nuts until proper height is achieved. Make sure that the Super Crown can rotate freely in the machine so that the points self-align with the existing crimp. (Below: Super Crown mounted on a MEC 600JR)

A must have
Wanting to hot rod my beloved MEC Sizemaster I ended up getting the super crown crimp starter. Be it known though, I originally got this only to hot rod my press, thinking to myself how can another crimp starter be better? A crimp starter is just a crimp starter. But went ahead and ordered anyway. When I received, I was pretty impressed by the quality of the machine work on it. I installed it which was effortless and ran a few practice hulls through. While the original crimp starter that comes with your MEC is pretty awesome, to be honest, it doesnt come close to this superb upgrade. The folds in the crimp due to this new starter safely crimps with out cutting anything, but be assured, youll never ever again worry about a crimp not being started just right. I am only reviewing for the 6 point as I got for crimping buck shot loads. However I am going to quickly get an 8 star for turkey loads very soon. This is NOT a waste of money to get.

Used hulls?? 4/30/2024
A very solid product, well made. It may work well with new hulls, however not so good with reused hulls. Crimps will bulge out the side. Im going to try to modify it with a band around the crimper to prevent that.

The Super Crown is designed mainly for new hulls. If used on once-fired hulls, it must be aligned with the crimp folds.

Best crimp starter on the market 4/25/2021
Iím using mine with range hulls on a Mec Sizemaster. I eliminate the spring and rotation by using 2 washers to adjust the depth and wingnut to hold it firm on the press. I just visually guide the old crimp inline with the points on the crimper and pull the handle, perfect every time.
Produces perfect crimps on new hulls 1/5/2021
I already reviewed one of the small crimp starters but I had to get this out for all of them. I have 12 now of BPIs brass crimp starters and if you load new hulls this is the way to produce perfect crimps. Reloading isnt necessary to use these once the plastic has taken a memory set but the initial crimp on a new hull requires a good sharp edge. They do work well on reloading as well if they can rotate freely. I use this particular starter on MEC 12 and 16 gauge Grabber and Sizemaster presses. On these presses you need to install these with about 3 small washers and double nut them on the top allowing a little free rotational movement. The spring supplied makes it too long to allow a full stroke on these presses. This method works and I have been making perfect crimps for a very long time with this method. I also break the sharp edge of the crimpers with a hard Arkansas stone so the plastic isnt actually cut. I highly recommend these. They are worth the money to produce perfect shells every time. 4 stars only because they dont work with the springs as described.
WOW 9/5/2015
40 years ago I bought a 600jr with the money I did not waste going to prom.Good investment. The MEC still works and looks good,would not bet on the girl. This crimper works better than the original. No cut hulls. Should have picked it up years ago.

Well worth the outlay. 2/20/2015
Recently purchased a MEC 600jnr and a short kit in order to start loading the thousands of Cheddite 2 1/2 cases that were too cheap to pass up. After fair number of failures I contacted the good people at MEC who gave me a lot of good advice but to no avail. so I tried your Super Crimper and within 3 or 4 attempts I had what can only be described as a professional crimp; it gets right up the noses of my mates when I flaunt my loads.
