For instance, the Speer bullets I had been using in the '06 were coming apart. I think it's more critical to match the weight to the bullet with consideration for the animal hunted. I have had great results with the Sierra's in spite of the bad press they get, including complete pass throughs on mule deer with 140gr out of a 7mm RM. I think the Hornady Interlok is way under rated. The 52gr.224' with the large HP kills coyotes very quick out of my mini-14 and so I use them.ДЇor bigger game I will use Hornady or Sierra's before Speers for deer and elk if I'm using standard construction bullets. That was 20 years ago and I have only bought one bullet type from them since. I got my Dad to switch to 180gr for the '06 and they were better, quite possibly due to the lower velocity and greater mass. They shot ok and great in an '06 but fell apart on deer. If I had to chose one brand over the other it would be Speer but I sure would miss the interloks.ДЈ0 June 2005, 20:46 BigNateI had been using mostly Speer bullets when I was a teen reloading on my Dad's dime. 308 bullet as it is a favorite deer bullet in my 308 and 30-06. These I mostly used on elk with the exception of the 150. The Speer bullets used are the 160 grain Speer. These mostly on deer and hogs with one elk thrown in to the 150 grain. 284 flat base interlok and the 350 grain.

270 flat base interloks, 150 and 180 grain. Hornady bullets I have used on game are the. Hornady bullets seem to open more quickly and wider losing more weight than the Speer Hotcor which gives deeper penetration on average. I give the Speer bullets and edge in penetration weight for weight but feel rifles are individuals as to which bullet they shoot more accuratly. 'Interlocks' are a mechanical lock rather than a chemical ('bonded') lock.Дў7 June 2005, 01:59 rickt300I am a hardcore Hotcor fan and also like the Hornady interlok. Bonded core will likely hold its jacket better than other bullets, but likely won't do as well there as partition or solid copper bullets. They perform well due to the lack of a flux that's applied to the lead for ease of manufacturing the lead doesn't slip in the jacket as easily. HotCor bullets are not bonded core their performance is not based upon lead 'melting' into the jacket material. I would expect both to perform adequately on deer and hogs, but I think I'd give the edge to Hornady, however slight. Maybe they get a more accurate run of bullets. Oddly, some Federal factory loads use HotCor and perform excellently. So, if the OAL remains the same, and the weight varies, where is the extra weight stored? It's stored in the varying ogive length, and that explains its lack of accuracy in my rifle. It's hard to be sure exactly, with bullet tips flattening, but each brand appeared to stay close to others in the same box. I then measured the Overall Length, and things cleared up a little. Hornady max variance was 0.006' variance, compared to 140g Nosler Partition at 0.001'. The measurements varied for the Speer from 0.729' to 0.743', a significant 0.014' variance when trying to set a 'jump to lands' distance. I then measured all 100 from base to ogive, using a Stony Point Cartridge Comparator, and the results were even more startling. Speer weight varied a grain, and Hornady's measured significantly less, 0.3g, IIRC. I weighed and measured all 100 of each box a couple of months ago. The Interlocks (129g SP) average under an inch at 100 yards, while the HotCor (140g) average closer to two inches (three separate lots). 24 June 2005, 22:21 JaywalkerI've had poor experience with Speer HotCor compared to Hornady Interlocks, as far as accuracy goes in two different 6.5X55 rifles in handloads.
