I got this a couple of weeks ago. Cleaned it, sighted it in, conditioned the barrel and I can say it becoming 1 of my favorites. Here's a 10 shot chrony.

Hi All
Have been lurking on the forum for some time and just today I brought home my fist PCP, a new Brocock Bantam Sniper HR.
I have a lot to lean. I was playing with the bolt action and it dry fired without touching the trigger, safety off.
I could repeat what happened if I cocked the hammer and slid the bolt back fast a second time.
I made a video and was wondering if this is normal? link below (not sure if you will be able to see video or what the best way is to share videos here)
Bantum going off when cocking
I also pulled the Mag apart as alignment was poor fixed by holding and tightening screw.
Cheers

I have not experienced that with my bantam. I would give a call to whom ever your bought the gun from because that's not normal. I did not have problems with my mags also, I might have been one of the lucky ones, maybe my mag was assembled on a Tuesday and not a Friday at 3pm when the person was getting off of work and thinking about the cold drink that's waiting for them.
Aloha

Nice airgun but going off when cocking the bolt thats just a bad accident waiting to happen. Hope they take care of that issue quickly for you so all you need to worry about is running out of pellets, again nice airgun.

sorry to hear that, i tried to copy that and mine does NOT do that. it reminds me of an issue i had with another gun awhile ago that involved a rounded sear piece.

Johnny,
Looks to me like your sear-engagement is too lean. Should be easily corrected through trigger adjustments. Dial in more sear engagement, Bud.

Thanks for all replies. I didn't think it was normal. The trigger is light will look at adjusting the sear-engagement.. would that be screw D?

Yes, looks like screw D must be sear engagement.
If you unload the gun, cock and close the bolt, then slowly dial screw D clockwise until the gun goes off you'll discover just how lean your sear-engagement was. I'm GUESSING you'll want to back-off screw D counter-clockwise 1/4 to 1/2 turn beyond where it started out, in order to find a SAFE, but still clean, trigger-break.
Keep us posted.

Finally go the Sniper HR .25 up and running. But looks like I have a way to go. JSB Kings 25.39gr seemed to work OK (which is what the Guy that sold me the gun recommended) I tried some H&N Sport Silver points but struggled to get within a 6" group at 50m! Thought I would do a ruff sight in with the H&N sport Silver points but couldn't hit a piece of A4 paper at 50m meters!! I then cleaned the barrel with Ballistol and a PatchWorm kit. it was quite dirty.
After that I shot two groups at 50m with the JSB Kings 25.39gr still not that good. I have a Combro cb-625 MK4 Chronograph that measured average velocity at 820fps.
What accuracy should I expect from the Bantam?
Also I noticed the regulator pressure doesn't seem to hold and seems to drop as the bottle pressure drops ( bottle pressure still above regulator pressure).
Mathew on Youtube found the same thing https://youtu.be/jWTFceWOMl8 see 8min mark. is this normal for the Brocock ?
Cheers

Aloha,
I did not see my regulator needle drop as the air tank pressure dropped. But I do notice that when I refill the tank my regulator needle climbs a little but after the first shot the needle goes back to where I have it set.

I Will have to do some more work on testing the regulator and record the speed difference over a string of shots to see what is happening.
On another subject, someone very helpful from AoA Contacted me out of the blue. I think he was concerned about the accuracy of the two groups I posted and just wanted to help me out! What amazing support you have there in the US I was blown away. Anyway I found out that I do not have a adjustable hammer which the guns are getting in the USA. apparently in the US there is a visible adjusting screw on the back of the hammer.
Mine looks like this

Since your rifle diacharged with the bolt open did you is it possible you lost the oring? This is a known issue with the brocock and may be a cause of the inaccuracy.

Hi Gipper yes I'm aware that the oring problem and it did jump out when I made that video. Getting it back in is not easy I am not looking forward to doing that in the field.
I have also adjusted screw D out a 1/4 turn, all good now doesn't go off when pulling bolt back.
I'm interested to see what the back of the hammer looks like for the .25 on guns bought in USA. or from AoA.

I have a Sniper in .22 and the Huma regulator in my Sniper likes 145-150 Bar, the gun will start to settle down after a tin of pellets. My Sniper was not that that accurate at first but after shooting a few tins groups tightened up considerably. Mine loves 18.1 JSB Exacts and shoots them over 900 fps. Getting around 90 shots per fill.I put a dab of moly on the bolt shaft and this smoothed cocking out as well. Also adjusted trigger to just under a pound. My advice, keep shooting gun. After 90 shots the velocity starts to drop considerably, goes from 910 down below 900 in a hurry, when the regulator pressure starts to drop below set pressure, it's time to refill gun. My FX Crown is no different.

I hear most shops give out some test results when they sell a PCP. I was wondering what would be considered a pass mark or acceptable for something like a Brocock Bantam Sniper HR in .25 ?
A photo of my Sniper. I would like to put a better scope on but not sure what one. I had the BSA 4-14X44 Mil Mil FFP laying around and thought I would start with that, it's been surprising good for the money.

The jsb 25s in 25 are most accurate for me over 900 FPS ...my cricket spits them out at 950 with laser accuracy and my streamline is pushing them at 915 FPS with the same results .maybe try getting your bantam up in FPS and test for results .
