Today i put 4 cold bore clean shots on target at various ranges to check bullet drop for hold over.

25 and 50m are perfectly on point of aim and suit my purpose

70m and 95m are easy to hold...

Clean cold bore 30m proof of concept shot this evening

First shot ever at an animal so happy with the entire project

Reload all the cases from todays range session and hunting and go look for...

Marty Henry You talking about me or the rifle ? !

Seems happy at least to shoot clean or dirty well enough for the intended large target species

I just did these two tests

45-60 50 grains 1 1/2 FG Black powder 350 grain PC Cast lead bullets.
30m from a leaning bench

Bottom group was shot first and wiped clean between each shot. So shot...

I found an old roll of glow tape in my possuming kit.
Will cut a tiny strip and try it out when I have time to see if it is overpowering or ok

If any good I will go the glow powder and clear nail...

So where do you guys buy your glow in the dark nail polish ?

Could also be good on the fore sight 250237

So what the BP cast lead load is screaming at me is that the nitro load that only half filled the case is very inconsistent and that the BP load which is 105% full is very consistent

I had better...

I can confirm that it like Black Powder

360 grain cast powder coated loads. 50 grains 1 1/2 FG and over powder card slightly compressed

I forgot to mention re the Epoxy
Acetone clean all the parts prior to final epoxy fitting

Mix about 3 or 4 table spoons worth of it to get it well mixed and accurate.
Put plenty on as the liner...

For anyone interested in how this conversion was done here are some missing details on the process I used.

There are clearly a lot of little tips and tricks.
Just remember when epoxying in a...

Boxton Plenty

I was running it with a little toilet paper filler because 4198 only half filled the case

There was plenty of 45-60 300 JHP IMR 4198 data so that was the obvious first try out.
I use that powder in Nitro for Black loads and it runs clean in those with wool filler.

I will try all these...

That's sort of what its intended for

During the roar I was off hunting on my own one day ( the guys I was guiding had celebrated a bit hard the night before ) and I got onto a couple of stags in...

This project is complete and test fired
IMR 4198 300 grain JHP increasing loads all shot well
But even as pressure increased unburned powered stayed high.
So some work to do there

All two shot...

Formed 45-60 brass and dummy round used to cut chamber
Bottom is 45-70 with the same 300 grain JHP bullet

I did do an interesting comparison of foot pounds of recoil with this shotgun

16 gauge 350 grain slugs at 1500 fps in a sub 5 pound gun
30 foot pounds

Lined and chambered 45-60 ( well my...

I do have 5 rounds of 16 gauge 00 Buckshot and I will try them.
But no bunnies outside my back door here on Banks Peninsula, some hares I prefer to look at and a pet cock pheasant.
So a 16 gauge...

I did the calculations on the weight of a 40 and 45 cal liner and the 45 won.
Because the weight being added is all forward of the breech face I want the biggest bore that fits safely into the 16...

No I'm actually most likely to go with 45-60 because its easy, won't chamber any of my hot nitro 45-70 rounds, will get a lighter 458 bullet up to 1500 + fps easily, will be barely 7 pounds and very...

Noted Boxton
But aside from it being a bit light for a 577-450 the area of the head of that case is much larger than the area of the head of a 45-70 case.
So the force exerted on the breech face...

That would have been nice but it wouldn't be nearly heavy enough when finished
A 7 pound even 577-450 would not be the nicest rifle to shoot well

But Ross Nolan I like your thinking

16 gauge nitro frame

VS 500 3"BPE frame

248730

First thing I did in the conversion process is solder on a period correct front sling eye
This needs to be done before the liner is fitted an epoxied into the barrel

Now wait for a...

Sadly a Nitro cylinder bore 16 gauge shotgun under 5 pounds is of no use to anyone
I knew that when i brought it
But was curious to see if ( as it looked ) it was built on the same frame as my...
