load for hollow base pistol bullet vs...

[egd]

I have a load for my 9mm pcc for steel challenge using titegroup and RMR 95gr FMJ bullets. Since they are so far behind they don't list those bullets on the site now. I see i can get some Berrys hollow base 100 gr bullets. Do I need to make any big adjustment for loading with hollow base vs flat base bullets? Is there a big difference?
I know the drill, reduce load, work up, yada yada. I'm just wanting to know the inherent differences between hollow base and flat base. Thanks.

I use Berry's 124 HBFP and HBRN and make no adjustments compared to other bullets of the same weight and shape.

Not really any significant difference as the hollow base is a slightly longer bullet yet they still both fill basically the same volumes.

Also not familiar with the TG powder loadings but the Western Powders there is usually a slight variation.

OK, thanks. I thought I had seen something like that once, but I've slept since then, so....
