I don't think so. As long as you have proven that ammo choice in your own guns. Most ammo will perform fine from most guns... does that leave some gaps? Sure, but as long as the ammo runs in your gun, that solves 95% of the problem. Is it possible to get slightly better performance out of each gun by tailoring the choice for each? Maybe, but that's a LOT of time, money and effort.Soccerdad1995 wrote:Am I losing much by just running the same weight and type of bullet in guns with different barrel lengths?
In the discussion above, we're splitting hairs on a particular round in .40 cal... because it's a slow day.

Grundy- look up DIY ballistic gelatin (with knox gelatin). There are a few ways to make it- a couple get close enough to calibrate. And after you shoot it up and recover your rounds, you can remelt it and use it again.
