Thread: 45/70 SUBS

Hi guys .. I'm after a bit of advice on previous experience using 45/70 subsonic rounds. As some of you may know I am a bit of a fan of 45/70 but find the mighty SBL a bit noisy in the tight confines of the bush. I don't want to modify the beauty by chopping it up to add a surpressor so have been considering a bergara single shot to surpress. I have spoken to a few people who have all tried their best to put me off the idea. Rainbow trajectory etc etc.
I would be using the new Hornady subs as I don't reload. They are 420gr and are advertised at 1050 fps. They would be used short range only and maybe the odd possum. Just how quiet can they be made with a standard sized can bearing in mind the size of the hole in the end?
I have found trying them in the SBL that they are no quieter than standard ammo unsurpressed and with the normal rounds sighted at 100 meter zero the subs seem to be pretty much dead on at 50 meters. How much more drop would be expected out to 100 meters? And if sighted to 50 mtrs with subs how high would they be at say 20 meters or do they shot fairly flat for the first 50 ....?
I have a rifle all lined up to purchase but now I am second guessing the purchase....
Should I or shouldn"t I ......
