243 90 grain AB 3075FPS

[SJB358]

Pulled this from the 4th jug today. Weighed 42.8. Pretty accurate little bullet in my boys 243 as well.

 

[DrMike]

I like that. I am working with a young lad who is building some loads for a .243. We opted for 100 grain PT and 90 grain E-Tip for his working loads, but I believe the AB would work just as well.

 

[SJB358]

Yeah, out of those three you can't lose. Up in your area, the ET would probably work really well. Might have to give them a try if I ever see any for sale. Seem like well made bullets.

 

[FOTIS]

YUP I am driving them over 3450 from my 240 Bee. They work just fine.

Yeah, I would like to pile drive a coyote or something with one. They are super accurate in my son's rifle.

 

[EOD Diver]

Nice test man. I gotta try the 90 AB in my 6mm Remmy. I'm burning 75 BTs in it now for coyote, but want to go to a dual purpose bullet that works for deer and dogs. I think I can knock down about 3200 FPS with the 24" pipe.

[SJB358]

Yeah, I would think so Joe. I would think it would be real easy. Only a 20" barrel on my son's rifle, so it is a little limited, but it shoots well. I'd go 22-23 if I was to ever rebarrel it though.

Scotty,
Thanks for the QL data. I need to find some RL 17/19 for that 6mm. Looks like it's the hot ticket.

Scotty,

Looks great. That will do the trick on WT deer.

Only 7 grains difference from 3075 to 3700 that's impressive!!

 

[SJB358]

Here are some shots taken with a reduced load. Speed is probably around 2300 or maybe a little more.. Bullet looks real good to me..









:twisted: :twisted: :twisted:

 

[DrMike]

Pretty good performance, for sure.

 

[CatskillCrawler]

So if you were using your 3072fps load with these ABs, you're looking at your terminal performance @ 300-325 yds. Very nice. Never saw a deer in any of my years that could walk away from that!

Perfect bullet for that cartridge in my eyes.
