FYI: Did some down loads with my .358x41, using Blue Dot, H110 and Trail Boss.
With the Blue Dot 185 grain bullets and 200 grain Were fairly accurate but very sooty sooty.
Same thing using the H110.
The degree of soot indicated that further reduction could well have caused gas in my face. In the past I have had this happen'
The trail boss was used with a 168 grain gas checked bullet. Performance was not great, but there was hardly any soot .

The recoil for each load was negligible .

The guy on the bench next to me was having accuracy problems with his bolt action .308. The reloads that a friend of his loaded for him were no where as accurate as store bought ammo.
The reloads had a huge variety of commercial and military cases,
The OALs seemed to vary.
I could pull some of the bullets easily with my teeth.
At that point I didn't want to go any farther with an evaluation and the shooter told me he would never again use reloads. SAD day! roger

yeh, those public shooting ranges produce some interesting characters as well.

guy next to me was shooting an AR. He shot over a 100 rounds and some of the time I was getting hit with his empties. I let him use my fold out case as a back stop and that helped.

Accuracy was terrible. he was resting the barrel on the front rest not the fore arm.
after a short conversation he convinced me that he was an expert.

EXPERT= X meaning has been.. SPERT= a drip under pressure

Be careful using Blue Dot for reduced loads. It's fairly well known to blow things up.

Did you try to explain to the guy that it's not reloads that caused those problems but, the experience of the guy doing the loading and adjustments of the dies? Not all reloads are of best quality, same as new parts don't mean they're good to use regardless of what they're for.

Not to mention reload for someone else's rifle, I'm sorry I'm not wasting my time developing loads for someone else's rifle.

And the two public range stories. Case and point why I drive 200 miles round trip to shoot where i do with only the people i invite. I have no tolerance for idiocy experts on the firing line

Thankfully I have a great range at my house, I can hear all of your stories and just laugh.
I used to shoot at a membership range that was an absolute zoo with "experts" and saw plenty of things to scare me and make me just shake my head.
