Bad day for Blackhorn

[smokeless77]

When he dumped his powder measured load down the barrel the 777 on top will be the first to go. Thats what I'm thinking anyway!

Mannnn,it sucks getting old . I really like the idea.

I have shot BH out of my Savage time and time again with never a misfire. I use the Fed209a primers ( the hottest), and have shot a variety of different bullets and sabots. I weigh and put all my loads in small plastic vials go to the range dump them in load the bullet it goes BANG. I really dont know what to tell you. Bad batch of powder, primers or bad breech plug design

I'm not going to worry too much about it Mike unless it happens to be a problem.So far with the CCI primers my incident rate has dropped quite abit.Powder,primers and breech plug are new.I am shooting a 700 Rem converted.

nmaineron,

Sometimes a cci 209m primer will make the bullet and sabot exit the barrel. It might hit the ground 10-20 feet from muzzle.

If this is the situation you have, then your sabot/bullet combo is way to loose!!!!!!!!!!!!!!!!!!!!!!

IMHO, Your Sabot / bullet, if properly fitted might move slightly if the powder didn't light but to be ejected from the bore is not tight enough to build the proper pressure to insure that the powder will burn. Most powders require a minimum pressure to properly burn, if this pressure isn't achieved it will not burn.

I don't have a loose load problem.I think for some odd reason I had a load where only a portion of the load ignited.

I have a theory about how that may have happened.

The temps were in the 20's and I set my rifle down to go and check the target.I think that the warmth from the barrel with the temps being cold formed some moisture.It took me five or ten minutes to get back to reloading,maybe enough time to form some moisture.

As for my load being loose.On the occasions that I had hangups, I would check to see if my load had moved after I let it set for a minute.Only a few times did the load ever move and when it did it would only be an inch at the most.

Most likely it is the leakage of your ignition system causing the problem. I modified my 700ML to the Savage style ignition and it has no blowback at all. No blowback means 100% of the primer fire is going into the powder. Ignition even with BH209 is like a centerfire.

[nmaineron]

Blackhawk,I am not familiar with any other ML's What are the differences from my 700 which I have converted with the laest breech plug offered by Cabelas.I do get some blowback but not nearly as much as before.

I can live with how my rifle performs but I am a tinkerer at heart.I would like to get another breech plug and experiment with it by drilling the passage a bit at a time.I haven't read about any modification done other than changing over to a center fired 25 cal. shell that appears in another thread on these boards.

Just thnking though,opening up the passage may just backfire and allow more blowback.The powder is only going to burn so fast.

Here are the photos of my 700 ML conversion. These photos were taken after 15 shots with BH209.
The primer seals on the nose not the sides and does not leak at all.


Any ignition system that leaks is going to have some problems with BH209, it is meant for the more modern sealed priming systems.

Nice,you sure you didn't take a rag to that before you took them pictures ....So... how does your setup differ than Sabotloaders?

I can't seem to find a Savage anywhere to take a look at.The nearest shop is 50 miles away and the other is almost 100 and neither really has much on hand.

I did look at a new rifle today,Apex I think,soft rubber stock and the knurled knob that allows you to take out the BP.Pretty fancy and nice but I like my Remington and all its quirks.

[blackhawk7204]

Mine has a normal diameter firing pin threaded into the shortened original striker.The piece I added to the bolt also holds and extracts the 209 primer by the rim.
The breach plug is the original Remington but has been modified to include a short snout with a vent liner that closely fits into the bore. By using a vent liner like the Savage you reduce the amount of pressure that can get back to the primer so it is much easier to get a 100% seal at the primer.

Blackhorn is not water soluble; you can put it into a glass of water leave it set for a while pour it out into a strainer dry it on a paper towel and shoot it I have done this. If you got some APP or any of that group of powder mixed up with it and put the wrong powder in or 777 for that matter they will turn to mud. The only way you could get Blackhorn to do that is by using a nitro solvent.
Any one that doubts this should put some in water [ note it does not lose it shape or consistency] strain it out of the water dry the water off on paper towel and light or shoot it.
