Hey, another thread resurrected from 6 years ago.
Nothing's really change in the last 6 years ... aside from ammo shortages and scalped pricing.
I personally wondered if the new commercial Ultimate Defense was just a way for Remington to boost the price while cutting the box size from 25rds down to 20rds. Remember when Remington advertised they gave customers an extra 5rds (25rd boxes) for the same price the other major ammo companies were charging for 20rds? Well, apparently they saw the writing on the wall and decided to go for the bucks, after all.
If someone wants to look at the commercial ballistic testing that uses synthetic gel blocks, keep in mind the advantages of using the synthetic for the testing companies ... but how it's been observed to see results of bullets tending to under-expand and over-penetrate in the clear synthetic gelatin, compared to 10% calibrated gelatin.
Also if you're going to look and compare the LG website's testing of the 230gr Remington .45ACP loads, look at
all of them.
Me? I'll continue to use my remaining supply of W-W 230gr RA45T (and some RA45SXT, if think may still be left over), Rem 230gr BJHP/HPJ
non-bonded (because I want
expansion as well as penetration), and the 230gr HST I was also trying and using before I stopped serving as a firearms instructor/armorer. They all seem to work fine in reported actual conditions. I'll save the supply of W-W RA45TP +P for the larger, heavier .45's I still use from time to time.
Last time we recorded some velocities comparing standard pressure and +P fired out of a short .45 barrel (3.25"), the difference was less than 40fps, but the results in the organic gel block were virtually indistinguishable. Why bother with the increased muzzle blast, felt recoil/muzzle whip and slide velocity for hardly any difference?
I think I still have a box of Speer 230gr GDHP somewhere, but Speer isn't quite as popular out here (finding it), and Speer has a very high opinion of their ammo (reflected in higher cost), and the ballistic results aren't that much different, except maybe for how some pistols may be less tolerant of the nose cavity size and OAL of the round.
Basically, not much has really changed in the last 6 years since this thread was started. Not really.
