well i have this foaming shat in a can that turns colors when the barrel is clean of copper, it is a black can with blue words, can't think of the name but the stuff works!! This is just a round I would like to make for a custom gun, I will NOT be rechamberling the Stealth I have it shoots too good

I often wonder "what if",but there is a website on wildcats where they have done about all of it,including playing around with 18,19,and 21cal. bores.Which makes me wonder what would happen if you took the WSSM case and pushed the shoulder back to about 20deg.and necked down to .20cal.,which does so great in the .222mag case?That shouldnt be hard to come up with.I would think you could get a .20cal barrel cut off and reamed for the WSSM case.It would have to be rethreaded for an action.By reducing the angle of the shoulder,it might feed better. I may get serious about this one. sam.

I am not big on 20 cal I was actually looking for more speed from the 223 WSSM (yeah like it needs it) but AI would... should... significantly increase velocity fo those long shots. Someone on a different forum made a 204 WSSM with a 35 degree shoulder angle he is pushing a 32 gr at 5000 fps froma 29 inch barrel

samuel · 05-04-2008, 02:57 PM

The reason I was thinking .20cal was because of the way it is ballistically superior to the .22-250 at longer ranges.A 40gr Vmax in both cartridges makes the .20cal.capable of equaling the .22-250 at 300yds and leaving it in the dust at 500yds.I wouldnt be intrested in setting speed records,just something fast and accurate,mostly accurate.I would still like to see what can be done with the .22cal but in my opinion the gain might be little compared to the expense.I assume I could gain more with a .20cal. sam.

but the flattest 20 in the world even though it will out preform a 22 is more succeptable to wind drift...

I find,due to less time in flight,the .20 with same weight bullet,and less exposure to wind due to smaller diammeter,is bothered less by wind.This isnt book jargon,it is experience on the range.Looking at my records,the .22-250 was drifted 8" to10" at 300yds where fps is about equal and the .20cal was drifted about 6" to 8".It doesnt say but this must have been a moderate wind,say 10mph.At 400yds the .20 wind drift was about 1/4 less than the .22.There is only about 50fps difference,so it has to be the smaller dia.. sam.

ok point seen. but there is no arguing that the heavier bullet will keep it's velocity longer with more down range energy

I was using equal weight in both .20 and .22cal..40gr,s.The difference is frontal mass.The .20cal has less drag.Having the same weight,the .20cal will surpass the .22cal. samuel.

338RemUltraMag · 05-04-2008, 09:12 PM

but with same weight bullets the 22 will go faster because the powder has more of a base to push against :-) this is fun

K so i am guessing mine is chrome lined...BUT how do i tell???????

338RemUltraMag · 05-04-2008, 09:33 PM

all browning and winchester rifles in 223 and 243 WSSM are crome lined

sell33 · 05-04-2008, 09:34 PM

ok good i figured that was the case lol.

PS last night my m70 featherweight shot a 5/8" group in 20-30 mph wind

group was about a half in to the right of center at 100 yds so i guess the drift was equal or somethin lol

actually 2 groups about that size. I only shot 3 to check the zero....first was cold and about 1 1/2 inch.

338RemUltraMag · 05-04-2008, 09:43 PM

nice groups... keep emptying that brass LOL how many rounds per group? before I go whistle pig hunting I always shoot a fouler shot so that is normal, your first group should be larger

sell33 · 05-04-2008, 09:47 PM

just 3 round groups, but i am confident i could have kept 5 or more within at least 3/4. I just cant believe how well that gun shoots and that is only with factory ammo!.....i will have to do the fouler shot i never have, i have missed a groundhog once though, with no fouler, at 300 yds. Maybe with a fouler he won't go anywhere next time.

338RemUltraMag · 05-04-2008, 09:53 PM

well a fouler is needed because when you line in your gun you don't clean the bore after every shot, so the gun is lined in with a dirty bore to get the same accuracy you have to create the time from which it was lined in including a dirty barrel

The .22 does start faster but because of larger frontal mass creating more drag,slows down faster. sam.
