Sniping BB Weights

Recommended Posts

Now I have my sniper up and running, I need to get some BBs to ru through it. I tried Longbow .40s and they were ok but I had a few fliers fairly often, too often for comfort.

 

The useful range is 50m, that’s where I can hit an A5 sheet with them. 65-70 for A4, anything over 70 is a wild guess. I have a Maple Autobot in AA VSR chamber installed, 6.02 430mm barrel and it shoots just over 500fps on .20s (site chrono Yesterday at 506, 503, 502), so I’m wondering now if I have the best brand, if I’ll be able to lift .46s down to A3 @ 80m?

 

Suggestions on brands and weights? White is definitely a bonus.

Have you tried washing your BBs? Not something I've personally done but some people swear by it

Not with longbows, they are hydroscopic.

 

I personally prefer Geoffs super precision, and I never have issues with them. How far is your hop dialed “in”? Have you enough room to use .46s etc without needing to R hop the barrel(if not done already)

 

Try a batch of Geoff’s .43s, see if you see any improvement, if you still have room on the ole hop dial, try moving up to .45s, the heavier BBs will travel further, just be mindful of joule creep, some sites chrono for this, others don’t, the ones you play at don’t if I remember correctly.

Im actually not 100% sure how much I have it dialed in for the longbows. The autobot bucking has a fairly long patch on it though, so the next best thing to r hopping without actually r hopping. I might see if I can get a little sample pscket of each of those BBs, rather than pay full whack for the .43s if I can go straight into .46s

 

Although, if the hype about novritsch BBs is founded on anything solid, they’re all bio now which is a bonus.

I would definitely try .46 or heavier. I run .43 in my 400 FPS DMR. A maple leaf bucking should be able to sky a .5 with enough pressure applied. 

 

As for BB’s.. geoffs I consider to be the best. I’ve also had no issues with the little tubs of accuracy international ASG BB’s (.36,.40,.43 I think) longbows are good too, I’ve only used about 2000 for testing and I make sure I keep them dry though.

I have have good results with asg precision .43g B.B. when I had my TM VSR. I have a left over bottle of 1000 I can send you for £13 posted if you wanted to give them a try.

I have a VSR GSPEC with standard TM hop unit and rubber. Have upgraded some bit son it and it runs roughly around 480fps (seems to vary at each site so I'm blaming the chrono). Either way I tried the ASG 0.4's when I first built it and they shot quite nice, very rarely a flyer but then I moved on and found the Geoffs 0.43's and I'll probably never go to another brand or weight. They are perfect, fly brilliantly and I have no problems reaching out with them, 4 "clicks" on my hop and they fly off upwards (not even half way up the levers travel).

 

Geoffs also do a 0.45 option (I think, it may be 0.46) if you wanted to go a touch heavier.

Not a lot to add here but another vote for Geoffs. Before our Striker ripped apart it's stock cylinder, 0.36 Geoffs were amazing to use.

Don’t use Novs BBs, they are ridiculously priced.

 

As much as I dislike the guy, Kicking Mustangs range of BBs are identical to Novs and a lot cheaper.

Looks like a lot of love for mr Geoffrey. Has anyone had any experience with Geoff’s .48s on an Autobot hop? It *should* lift them, at a push.

I’ve skied some .43’s with a 70d autobot bucking in a custom mega arms 308. Specs are:

 

430fps

410mm 6.01

maple leaf autobot

3D printed chamber

 

as long as you have the arm travel, you should be able to lift anything with that bucking

I'm on
500fps

430mm 6.02

autobot 70

AA chamber

 

So should be okay with the .48s you reckon?

As long as you have the adjustment range you’re golden. The bucking isn’t the issue in the equation

Saw you did a PTFE tape job on your hop. I'm hesitant to do that because I'm shooting a couple of FPS over 500 at the moment, don't want to push it higher. Did you notice an FPS increase when you did it?

Gave me a greater air seal, and gained a few mate yeah, if memory is correct it was in the 4-8 fps range.   

 

Simple mod though, done it on all my guns and I’d say if you can stay within limits to do it. 

 

You over with hop on?

I hadn’t applied much hop when it wasn’t through chrono at the site last week, was shooting 503-506 FPS which they didn’t mind, but if that went up to 510 it’ll be too hot.

I’d say leave it then mate to be honest. 

 

Not worth the risk, what aping you got in there? Could always drop the spring to allow improved air seal?
