Xp 100 advice

[desert shooter]

I was lucky enough to find an XP100 pistol in 7 BR that has a factory barrel on it. I am looking for some advice from those that may have shot this caliber with an original barrel as to which bullet manufacturer and weight would be a good place to start with. I believe the twist is 1:14 , but can't find any bullets designed for that twist. I was looking at trying Hornady 120 grn vmax or nosler 120 ballistic tip and speer 110 grn tnt bullets. Any input is greatly appreciated. I intend to use the pistol to shoot steel at various distances. Thanks for any advice

You might post this in the new handgun forum . There is a spot for XP100’s .

Thank you, I thought I was in the handgun section, but the xp thread would be a better location. Thanks again

I’m pretty sure the XP7BR are 1:9 twist. I shot them for years using 160 grain bullets for handgun silhouette

I am guessing factory barrels are 1-9 myself. Possibly a 10T, but I think they are 9T.

Thank you for the input, I don't have the pistol in hand yet because I live in communist California and have a 10 day waiting period. I can check the twist when I pick it up. That info gives me more options, I may try the berger 140 grn.
Thank you

Sierra says they are 1:10

Thanks Melvin, I just checked my sierra manual , which I should have looked at first , and it says 1:10 twist.

Thanks @Melvin!

every barrel and info I got from Remington in the 90's either measured a 9T or they stated that. I have gotten a lot of wrong info from Sierra. one is them saying 30grs of IMR4895 will fit in a 7TCU case.
