Just in case marauding elephants invade my subdivision I am protected.
Mcmillan BMG. 36” stainless barrel 1.7” dia. Weight without scope is around 48 lbs. This is prior owners setup, atm am also planning on a nightforce scope. His best group was under an inch at 600 yards. (3 shot). Seems a bit farfetched but he did have his own custom 800 grain solids turned, so I will try and duplicate. I also have the group pics and it was witnessed We will see what I can do. Pricey at about 90 bucks per 25 projectiles. The solids are 802 grain boreriders shot with 239grains (or so I have to check his notes) of VV 20n29 powder heated to 140 degrees. .

Second, as I do love blackpowder. 75caliber (10 gauge) blunderbuss.

Blasting away at stuff is not my thing and I like precision so a blunderbuss isn’t really my cup of tea.What made this one cool, the owner made some custom slugs and shot them out to 50 yards for fun. 6” groups at 50 isn’t too shabby for this.

the best part, he adapted a grenade launch sight to it for those high angle shots, good for storming the castle! If that gets boring then eight 33 caliber balls will make for some fun, probably will wreck my target stands along with the target

of VV 20n29 powder heated to 140 degrees.

Can you help me understand why he heated the powder?

Thanks,

from what I have read, that paticular powder is used for projectiles in the 800 grain plus. Under that people seem to like h50bmg. For that powder to work well u have to heat up the powder/round. Somewhere in the range of 100-140 degrees. Many use a food heater or their floor heater in their vehicle. When this is done, the powder is quite stable and you can really improve on your deviation shot to shot. He was in the 6-8 fps range, per his report. While this seems quite low in my opinion, he seems to know what he was talking about and I dont doubt him. If you google that powder and heating you can find some links, I had to do some reading also as it is new to me. It sounds like fun
