5.45 BS has identical performance to M995, yet:
Is a semi-common map spawn
Has the Redbull trade for 30 rounds
Is only 890rub from Prapor (60% of the cost of M995)
I run M995 and BS ammo exclusively in my ARs, I've rarely had to purchase BS from Prapor but I constantly need purchase M995 every single restock if I want to use 416s, M4s, or MDRs.
It's dumb, either gate ammo by price or by availability. Not both. I have over an ammo box each full of M995 and BS, 150 per restock doesn't stop me from running top tier ammo every raid – it only adds unnecessary busywork to an already grindy game.
Tarkov is a sandbox shooter, it seems absolutely bizarre that stuff like AP SX or AP 6.3 are gated in this way too. It honestly just feels like Russian bias as usual.
