Dirty Thirty

Ernie Bishop · May 20, 2022, 11:57 AM

This is BCG 308 Winchester XP-100, using a Remington Take-Off 308 Winchester barrel chopped to 15.8" Holland's Radial Baffle Brake, Leupold Mark IV 4.5-15, McMillan stock, and a factory trigger.

Video Below: Factory TAP with 168 A-Max.
Reloads: 1x fired Hornady Match 308 Win brass, CCI primer, H-4895, 155 A-Max at 2720 fps.
Groups were at 100 yards.

The last 3-shot group was by Dan Ekstrom, with his MagnetoSpeed attached and the group size was close to mine. This XP-100 shoots great!
Next up is doing some drop confirmations at distance.
Impact velocities will allow me to kill out to mid-range distances. Impact velocity at 550 yards should just a tad over 1800 fps.
It will be used for my personal enjoyment and hunting, but will also be a loaner XP-100 for WY-SHOT.
In The Video, I am shooting some older TAP 168 ammunition, so we could set up the resize die properly.

Why don't you sell that thing and buy a gun that will actually shoot?

So, how is your hand after that shooting?

Some of my XP's shoot tighter than this...truth be told.
Hand is fine.
I shoot much larger cartridges, in my specialty pistols.
Great muzzle brakes make a big difference.

sweet shooting

Wow… just saying.

Well done! Except for the color scheme, which I don't care for.

Thanks Guys!

That is a cool looking gun and it appears to shoot just fine, thank you for sharing.

Fine shooting and a splendid single shot. It's amazing how well these little hand rifles can shoot.

I sure enjoy shooting and hunting with them

Sunday afternoon I went out with a couple of guys from church. One needed to do load development and chronographing and the other one wanted me to chronograph a couple of guns with my Labradar. I wanted to do some drop confirmations with the Dirty Thirty/308 Winchester. We had winds from the north west, which was a quartering headwind for us. I was shooting to the north. After the guys got all of their stuff done, Glen spotted for me while I started doing some drop confirmations. The quartering headwind noticeably pushed my bullets down as I extended distances, but I still had fun.
Even at 300 yards it took me more elevation to hit my target, then it should’ve. By 400 yards I had a sense of how much I should add at 500 yards. At 500 yards my first shot at the 10-inch diamond target was close to a center hit.

The 5-inch square target to the right was hit by a guy shooting a 7mm SAUM rifle with 195 Berger’s.
I did drop confirmations out to 800 yards, but with wind continuing to pick up, I stop there. We shot Glenn’s 41 magnum Smith & Wesson revolver, and had some fun. I decided I wanted to shoot one more shot with my 308 Winchester XP. I picked the upper right small dot on the big rectangular target at 500 yards.

It always feels good, when you just have a sense of what it should be and you are right, and the shot is very close to where you were aiming at a mid-range distance.

I had a guy tell me once his XP-100 would not hit a mattress at 100 yds.

I told him that would be highly unusual. I also told him I had a high degree of confidence that if it had not been damaged ,I could get it to shoot 2 MOA or better at 100 yds.
It turns out the original 221 Fireball bbl had been rechambered to 223/5.56.

He was shooting generic Win White box ball ammo. I think 55 gr boat tails IIRC,the 221 bbl has a 14 in twist. His ammo was going through the target sideways.

I loaded him some ammo with 52 gr MatchKings,flat base. Shorter projectile, Suddenly,that XP-100 was shooting about like yours.

I can see why it was done, but that's still a sad story...
