May get either a Hart or Sinclair std flat-top br for shooting non-competitively my .22s - 30-06 sporters. I'm thinking the narrow owl ear front bags would be more for a br w. windage adjustment--am I correct? I'd think a wider front bag, or maybe even a brick or pillow bag, would allow me to adj. my aim more easily & thus shoot more accurately. Both makers sell All-Purpose tops but I'm thinking that might not be the best choice because you'd be stuck w. the bag that comes w. that top. However, the AP top would be ok I suppose if the bags could be easily removed & replaced w. one of the other bags I've mentioned. Is this possible? Any thoughts on all this? Thanks.
