BAM fitted with Walther .20cal barrrel.
with standard setting it output around 40ft/lb.
meantime it saves 25% air consumption.
Looks very nice but how many shots do you get out of one fill say from 190 bar down to 100 bar ? And what did it all cost you to do the conversion ? And would you advise other people to do the same if the use there BAM for hunting ?
And if you would who can do it for me and the price the would ask ?
CITY GUNS in cape town now offering the .20cal walther barrel conversion for any airrifles... give them a call for price.. tel: 021-4249030
becoz .20cal can saves 25% air after upgrade from .177cal. so it has more shot counts than .177cal. since my talon converted to .20cal. it offer me about extra 30 shots than .177cal. needless to mention the power increase...
the beauty of .20cal is: u can use much heavier and largger pellets to handle the wind and carry massive downrange energy in long range without sacrifice the accuracy...
cool...nicely done Boondock.
a word of caution here....
Firstly .20 is limited by the availability of pellets.
Also shooting at high power levels introduces a number of factors which can adversely affect accuracy.
Shooting a 40ft\lbs airgun is not as easy to shoot as a 12ft\lbs equivalent.
Be prepared to experiment with different power levels and pellet sorting, especially if using Dae SUngs and mandatory if using .20 Crapman Premiers!!!
Crosman Premiers seem to come in 2 sizes in every tin...pee wees and normal pellets...unless you sort them using a BIC pen and the drop-in method you can forget using them.
JSB .20s so far look really promising out of my HW barrels...more testing is needed tho...will report back soon at the 35ft\lbs levels.
Also in unregulated airguns such as the BAM you will be plagued by a horrific power curve at 40ft\lbs which will adversely affect long-range accuracy unless you only shoot 15 or 20 shots max between airfills.
Bottom line... .20 is fun, is capable of awesome results but requires a systematic approach and some patience.
Enjoy and please post more .20 experiences....
i don't think i will only get 15-20 shots from bam.. the bam .177 already give me 25+ full power shots.. now it's .20cal and plus 25% air save i should expect 30+ shots.
becoz my talon .20 can offer me more than 70 decent shots.. even only with 110bar left it still can panatrate the water filled bottle at 100yards..
best 3 shots group so far is sub inch at 100yds..
65yds 10shots in R5 icon size group is easy...
will test and report later...

yes Boondock you can shoot 3 shot groups of very small sizes ...but from the 1st shot to the 40th shot those groups are going to drop a couple of inches...so the 40 shot group would probably measure 3 inches...
So in a real life scenario ....you go out hunting with your BAM and are confronted with a 50M shot...unless you know at which point of the power curve your rifle is sitting at how do you estimate hold-over for such a long shot?
well. in that case.. all factory made .22cal rifle without regulator like BAM and SUMATRA should be even worse... they useless becoz their POI drop all the way?
i think all big bore air rifles like 308cal or 50cal are normally only take few shots per fill... if they worked well what 's wrong about shot counts of .20cal then?
in fact.. i think within sweet spot range.. the BAM's speed is very consistant.. if it can put 10 shots in a small group at long range then it's capable for hunting...
after all...we are not compare BAM with R16000 daystate air ranger...

yes...well said Boondock...
I am not saying they are useless at all...as long as people are aware of the limitations of high power...I am a big fan of high power .20s as you very well know..
All I was trying to point out in the above posts are the limitations of high power air rifles....and the need for a systematic approach and realistic expectations.
So, I avoid all the crap on 0.20cal by having mine in a gas-ram rifle = tried & tested. Go figure, all the trouble for above 20ft/lbs in a PCP and for what? Lots of experimenting and no real benefit, except for a learning curve, which Guido seems to enjoy.
What you gonna do with >20ft.lbs anyway?
Keep it at 18 to 20ft/lbs in a gas-ram and it more than suffices for hunting purposes...

errr Fucius...not so fast.
Can you shoot your RX-2 at 70yds+ and group under an inch consistently [if at all]?
It is pointless trying to compare a high power PCP to a springer...
And no-one said the above excercise was for hunting...it is just cool to shoot high power airguns at really long ranges and get them to group as well as match rimfire rifles if not better.
One chap from Robertson who frequents this forum [but does not post on it] and whom I have spoken to a number of times is an avid long range airgunner.
He only shoots his airguns on his farm at 100 to 150yds and allegedly gets some impressive results.
Gas-rams can't do that and are not much fun to shoot off the bench....but they make excellent hunters.
