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

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

 

[desert shooter]

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.

Either way it should shoot 140s fine. Id stick to 120s myself.

sierra 120's are my goto bullet in my multiple 7 BR's

Flat based soft point?

 

[desert shooter]

Thanks to all who responded, I haven't ordered the bullets yet and thought I would reach out to those that have shot the 7 BR in an xp . Greatly appreciated your input. I have seen the many nice XP 100 pistols on this thread and always wanted one,but hard to come by where I live. The one I bought is a factory original XP with the original "plastic" stock , but I feel lucky to have found one. Thanks again and it looks like I will start with the 120's.

Some have older benchrest rifles built on the XP 100 action.

1-9 twist 120 140 and 160s all stabilize and are killer

I am curious to the twist rate you come up with.

These XP 100 threads of a bolt action "handgun" do explain some of the other posts I'm getting about actual semi-auto pistols... particularly people wanting to shoot 9 mm at 25 yards to get tiny little groups. I admit I have never and don't ever intend to use a pistol as a Target gun. E.g, Bianchi, etc. For me - and possibly for me only - that is the job of a rifle.

So reading these XP 100 threads have helped me while I sheepishly admit I have nothing useful for helping other people on this subject. Thank you. Carry on.

I always found that the Remington 7mm XPs do like 130 grain Speer flat base spire points with 748. Was my 200 meter shoot off load. On used guns, I always strip the bore back to brite steel using Shooters Choice copper bore solvent with a chamber plug, filled bore, let sit for 7 days muzzle up. Then bronze brush scrup the crud out.
Then I seat the bullets .003 off the lands. The 357 Super Mag, 7 TCU and 7 BR have the same case capacity. So, 2015 BR, 748, 1680, 2230 all work, as do the 145 RCBS Silhouette hard cast bullets. with 4227 at about 2,000 fps.

Sir,
I will post what the twist I find in the pistol once I am able to pick it up, unfortunately I am still in the ridiculous 10 day waiting period that this misinformed state has. Decades ago we were a free state, but things have changed.
