Did it, question is, I'm 130 fps over already using a rifle, does it matter ? How fast is too fast ?

Too fast is when gun blows up in a vise, or rings your guide-rod/recoil buffer like a bell. +P+ wad cutters are awful interesting.

44MAG rifle

Do you take apart the action? That would be where you find any issues.

Not yet, only shot 5 rounds in the rifle, no signs of over pressure on primer nor brass. For normal jacketed bullets, like XTP I'd load them hotter, but I'm new to << plated >> bullets. So I don't know what the 1300fps limit is for.

Most likely to keep your pistols safe.

There are a number of things that can influence velocity and pressure. This can be barrel length, twist rate, barrel condition, temperature etc. Looking at the speed is not an accurate indicator of pressure. Look at the case and see how flat the primer is. If it is dead flat or popped out then there is an issue. Similarly if the case is hard to extract then it could be high pressure.

What you are seeing is typical of shooting from a longer barrel. The powder is burning longer and is giving it a bit more. Also, the pressure behind it is acting longer.

Long range shooters use longer barrels to make use of this. Depending of the cartridge you can expect around 30fps extra per inch of extra length.

You are getting about an extra 20fps per inch that’s about right for a 44 I would say.

You have nothing to worry about.

But don’t use the rifle loads you develop in the pistol. Develop loads for it independently

I keep looking and reading, just found something about high velocities knocking the plating off bullets. If these will hold up and hit at 100yrd I'll leave the load the way it is. Don't want to mess up a decent gun. Thanks.
