Not a rifle, but a 94mm anti-tank rocket.
The first was on Salisbury Plain - massive blast and heavy push, plus a thick plume of white smoke. It left me reeling from the overpressure.
Fast forward a couple of years and I ran an anti-tank range in Canada shooting them at an old APC. I had to be positioned just to the firer’s right and got the whole experience again, but 20 times in one day. Finished the day feeling like I’d had the shit kicked out of me and coughing from the gagging (and carcinogenic) smoke. The manual says no more than 10 in 24 hrs and I can see why.
Happy days.
