32 cal blowbacks

[Colt Fanning]

Howdy,
Lately I have been shooting a 1903 colt and a 1910 savage both in 32 cal.  They both shoot so erratically that I have to shoot at 3 yds to keep them on the paper.
Are 32 blowbacks know for this inaccuracy?  Are there any primers on how to accuratize a 1903 colt?
Regards
Colt

I have a Steyr 08/34 and Beretta 81   

Both are good within 7 yards ...the Beretta is the clear winner beyond 7 yds.  to 10 yards

I'm using Winchester 71 grain target FMJ

Both guns should be much better than that. I put Wollf spring pack in both my 1903 and 1907 and get good accuracy even with the original crappy sights. I also found out that mine are ammo fussy, but both like Winchester White box.
PS, the Triple K magazines actually work in both mine as well.
