Warning to all you who've read/heard all this before...
I had them deepened by David Clements. He's about the only one to trust with an ROA. I also have a couple of Classicbalistx cylinders that hold a bit more than that...and the latest ones are better than OEM.
I had this done because I pretty much shoot nothing but bullets. Bullets take up more room. Thus you need a bit of chamber length.
I started shooting Biglube bullets and they work really well. Then I had Tom at Accurate mold make a couple to my way of thinking. Essentially a Biglube with a much larger meplat. Then I sent it to Erik at Hollow Point Mold Service and had them converted to a HP. So I get a bullet designed to seat easily in the cylinder, doesn't slip under recoil, holds a bunch of lube and since I still use soft lead...expands really, really well. With the added capacity and the fact the big HP cavity lightens the bullet up...it spits out of a 5-1/2" ROA at about 950FPS with a max load of T7...confirmed by my chronograph.
T7 can really be compressed. Which is exactly what you shouldn't do. It says to only use firm pressure. It's like cotton when you push a ball/bullet down on it. Compress it a bunch and it becomes inconsistent. Not dangerous. Just a bit loopy from shot to shot. You can't blow up one of these guns no matter how much you stuff into it. I use an off gun loader with a positive stop so the bullet is loaded EXACTLY to the same level every time.
But...just for kicks...and it does kick. I smooshed 50 grains of T7 under a RB. Yes, you can do it with a Classicballistx cylinder. I believe it left most of the soft lead ball in the barrel...no idea how fast it went. A completely pointless exercise that I only did a 5 more times.
But I bet you could see the flame and smoke from orbit.
