1 year old GP-100 - cracked forcing cone

[Canuck44]

That is a pretty mild load. I use 15.2 with the same bullet. That cracking and erosion is very weird as well. I have a 686 with close to 10,000 rounds through it. Aside from some minor flame cutting it looks nearly new. Send it off to snapshots and say nothing of what you fed it.

Lyman Second Edition lists 14.9 gr of 2400 under FMJ to be max. 15.5 gr for a 158 gr lead RN as max. 11/3 - 11/4grare the min.

The top strap looks pretty normal to me. The frame is cast. My GP 100 looks the same at both ends of the top strap when new and has not changed since. Mine has around 3K light 38spl rds through it and less than 500 .357mag rounds. What you may think is flame cutting is just where the casting is not completely bead blasted. The barrel obviously has some issues and I am sure Ruger will make it right. The GP-100 has a well earned reputation for being tough as nails. I would regard this as an outlier. Doesn't make the owner feel any better though I am sure.

The nive thing about the Ruger over the 686 is the former has a much newer design for a trigger group. I have a 686 No Dash 4.214" and the 4.2" Ruger GP-100 and the latter is my Competition gun with the Smith the back up. Much smoother and lighter trigger on the Ruger. I did replace the springs and installed trigger and hammer shims to be fair on the Ruger.

Take Care

ps Just read where Ruger is replacing the gun.. They do have a well deserved reputation for looking after their customers. Quality control is not in their business model. Easier just to ensure their guns issues are dealt with.

Mine has 5735 rounds and it looks just fine. The strap erosion is more prominent though.
I know, I'm a stickler for round counts. All my centerfires are strictly counted. Don't judge me.

Glad they are honouring it. I have had good experiences dealing with Snapshots on other Ruger parts and special orders.

GP's are generally good guns, but this is not the first time I've heard of forcing cone issues on a GP.
