but I didn't see a better place to post my query.

I have a sporterized '88/05 Commission rifle. In deference to the 100+ year old bits, I have been shooting gas checked, cast bullets with a sized diameter of .323" (169gr.) and .325" (205 and 220gr.). Both fit easily into fired cases so I do not believe there is any sort of issue with the neck clearance.

The .323" 169gr shoot well (and this may be my answer at the end) but I wanted to try some heavier bullets; hence the 205 & 220gr. Book velocity indicates about 1600fps or so (not cronographed). However, all shots were keyholed at approximately 15 yards. First shot was at 25 yards and didn't even hit the target backer, so we moved in.

I know that increasing velocity will add some stability but I don't know just how much I can push this old girl before caution is thrown to the wind. Recoil is, umm, 'significant' with these heavier bullets and such a slim, light rifle, so that is another reason not to push much harder.

I have not varied the seating depth as of yet. Dad suggested that perhaps getting closer to the lands might get things spinning sooner rather than 'skidding' when the bullet hits the lands. Nor have I slugged the barrel but I have never heard of an '88 with a groove diameter larger than my bullets---not that I have heard everything.

All this leads up to, are there any suggestions? I don't wish to hot-rod anything but just how hard can I push before I am treading dangerously? Actual load can be supplied if helpful...I'm away from my notes at the moment.

Thank you for any input,
Hoot
