12GA Rifle From Hell

I should have figured that you would have checked. Your experiments are giving me one more reason to get a slug barrel for my NEF rifle. Not sure what I need it for, but I know I want it.
 
We got 600 gr slug to 2000 fps in NEF.Used ball
powder load. Case length of maximum 3.07 works.
Anyone using our style case should also put in adapter
for shotgun primer. Save a lot of work
beefing up hammer speed and strength.Ed
 
Savage is going great. Using little faster ball powder got
600 gr hard slug to 3000 fps, 12,000 ft lbs.
New supply of hard slugs comming. I think 14000 ft
lbs possible. Ed
 
For you fellows down under, Scott Wardle is having a bunch of rims and cases with 12ga rims made and will make them
for others in need.Ed.
 
We call it a Paradox gun. Using the word gun denotes
a cannon like quality.In a little while I will have a bunch
12ga rim pieces to supply those who can tke them and
thread the case themselves.Ed
 
Being some guns need to much work
to fire bmg primers, it easier to
do the following with adapter bushings.
Here is picture of cases for primer
comparisons.1st is regular bmg
primer. 2nd is adapted to a shotgun primer.
3rd is adapted to large rifle primer.
Of the 2 adaptations, large rifle is
easier to do, just ream out pocket, thread in adapter, but adapting shotgun primer
you have to deepen the original primer
pocket a little, then thread and screw in
a bushing.These two primers give about
100 fps less than bmg primer.Ed.

thats awesome!...simply awesome!! i want to try a .20 cal bullet with a necked down .220 swift case. call it a 20-220. think it would work? be a good cal.? i know it would be super fast!:) dude, great job on the cannon, youve created a monster!!
 


I always wondered about the over 50 cal rule and shotgun slugs.

You have blurred that even more in my mind.

I love that "gun"

Shot savage with 600 gr at 3250. That case
needed a little resizing on base, getting pressures up around 40k. Cases still extract
and Savage is ok, just bellers harder.
Like standing next to an 88.Ed
 
4 Bore?

Did you say you were also planning a 4Bore in the future. I remember seeing a 4ga shotgun in an old general store when I was very small. I will never forget how HUGE that thing looked. I really like your 12ga project and would absolutely LOVE to see you do a 4ga.
 
WE may deer hunt with it.Maybe put on smooth bore
and get some hairy goose loads set up also.

We are doing a 4bore as soon as bareel guy gets
set up to turn out barrels. Ed.
 
Testing NEF with short case, and stick powders.
215 gr of RL-25 got 600gr slug over 1700,
and cases eject easy. Gun still tight.Ed
 
Testing Savage with long case-Got 2550 with
320gr WC-855H special ball.730 gr slug.
Same slug,
300gr of RL-25 got 2400. 300 gr of RL-22
got 2800. 280 gr of W-760 ball got 2900.
Will hold more 760, but pressures around 40k on last
two loads mentioned.Savage extracts easy,
bellers like a tank gun.Ed
