We're actually both forgetting one more important detail. Who actually had Pulse Rifles?
If you watch the "Get on the ready line!" scene the team's armaments are (in order of appearance)...
Drake: M56 Smartgun / H&K VP-70
Dietrich: M240 Incinerator Unit / H&K VP-70
Wierzbowski: M240 Incinerator Unit / H&K VP-70
Frost: M240 Incinerator Unit / H&K VP-70
Crowe: M41A Pulse Rifle / H&K VP-70
Hicks: M41A Pulse Rifle / Ithaca M37 Shotgun / H&K VP-70
Hudson: M41A Pulse Rifle / H&K VP-70
Vasquez: M56 Smartgun / S&W M39
Apone: M240 Incinerator Unit / H&K VP-70
These weapons are mostly consistent with what's carried into the hive. The inconsistencies are as follows...
1. Apone's M240 Incinerator Unit is switched for an M41A Pulse Rifle. This is corrected though when the Chestburster comes out of the cocooned colonist. Apone takes Frost's M240 Incinerator Unit, and continues to use it until he is dragged off (Frost switches to a VP-70 handgun).
2. When taking magazines, Apone specifically demands Wierzbowski to give up his ammunition, despite Wierzbowski never at any point in the movie having an M41A Pulse Rifle. He's still carrying an M240 Incinerator Unit as they enter the hive.
3. Drake's M240 Incinerator Unit. When Drake runs out of ammo with the M56 Smartgun he switches to an M240 Incinerator Unit that just sort of magically appears in his right hand between cuts. Presumably he picked it up from one of his fallen comrades, but you never see it happen. Likely just a minor continuity error created by iffy editing.
So at the very most the team would have entered the hive with four M41A Pulse Rifles, assuming we give Apone his despite its presence being a continuity error.
As for Apone, it's reasonable to assume he still would have been taken out even if they had the Pulse Rifles. He was taken completely by surprise by a Xenomorph that nobody spotted (except for him, when it was already too late). Notably it was a Xenomorph that attacked from the ceiling. Given Apone's position in relation to the other Marines, he was either in the center of the group or at the rear - though the center is the one that seems most likely given what we see in the movie. So that means that the Xenomorph that grabbed him either came from a vent or something above Apone and wouldn't have been killed anyway, or it managed to sneak along the ceiling and breach their perimeter anyway. And given the Xenomorph's position prior to attacking Apone, if anyone had shot it with a Pulse Rifle, it would have completely showered Apone with acid. So yeah... Apone had no chance.
As for Drake, as it is, he already wasn't near the Xenomorph that Vasquez iced. The Xenomorph was directly in front of Vasquez, who was standing in the door on the right side of the APC. Drake was a few yards away from the front/center of the APC. Vasquez was actually closer to the Xenomorph than Drake was, but because of where she hit it it sprayed acid (which is highly pressurized) in an arc to the side - effectively spraying a cone in front of the APC that could extend outward at least a few yards. The only ways Drake could have survived would be if
he was the one to kill that Xenomorph (which is a big maybe,
especially if he still had ammo for his Smartgun - he either would have been sprayed anyway, or he might have killed
everyone standing inside the crew compartment of the APC) or if he had entered the APC
before Vasquez. And regardless of whether or not he was wielding the M56 or the M240, he wasn't going to be ending that shooting spree he was on since he
clearly was trying to cover everyone else's retreat and planned to be the last one to board the APC. So yeah... like Dietrich, Frost, and Apone... Drake was pretty much screwed. Though in his defense, his sacrifice
may have been the only thing that kept the Xenomorphs at bay long enough for the rest to escape.
Also, as for additional evidence of the kill count, every single Xenomorph killed in the entire movie "screams" as it's killed. All of them (including the Chestburster). The only Xenomorph death "screams" we hear in that entire sequence are the one that Hicks shoots at off-screen with his shotgun, the two that Vasquez and Drake kill during the retreat, the one Vasquez kills that burns Drake, "EAT THIS!", and the one that got run over. So that means that all the other shots fired in that scene were suppressive fire to keep the Xenomorphs' heads down and prevent their advance.
