    Speer Deep Curl Bullets can be hazardous to your health.

    I have deleted this post because I keep getting conflicting information depending on which tech I talk to at Speer. One tech almost scared me off of trying them (Deepcurls) and the next time I talked to another tech who said I should have no problems working up a load starting with a reduced charge and even advised me to not back off the charge too far if I was working with heavier bullets like the 225 grain .338 cal.

    Something seems fishy here. How in the world could Speer be allowing amatuer reloaders to have access to components that are so intolerant to deviation in speed and pressure. Surely they have to know these bullets will be used in a wide variety of calibers and firearms. I'm just saying....

    Same thing happened to me with the Deep Curls for a 7 mag. I loaded a box of them with H4831 to about factory specs and I emailed Speer and ask them about the bullet and asked them if it would be safe to shoot after reading their disclaimer. They replied to not shoot the bullet as it would build too much pressure. My question is not unlike others as to why they would throw a bullet on the market and then tell people not to shoot them because they might build too much pressure. The 2 powders they have listed for the bullet are powders I have never used and I guess these powders do not build as much pressure as others but seems like as BillyHill said in his above post that a lot of people will loading and shooting this bullet and not be aware of the pressure Speer talks about.

    The Deep Curl/Gold Dot bullet design does cause higher pressures, but I'm sure a handloader with some common sense could use them without dying. Although, I can understand liability issues without such warnings.

    A few years ago when Reloader 17 first appeared, I had a nice phone chat with a guy from Alliant at the other side of the ATK libalility spectrum. I called and asked if they had RL-17 data for .257 Robt's and 7x57. The guy said no, but did say the burn rate would be excellent for those two cartridges. I told him I plan on starting with the 7x57 and would likely just use their starting load listed for the 7-08 with their same Hot-Core bullet and work my way up with my chronograph. He thought that was a great idea and asked me to send him my results, which I never did.

    i used 44cal 240 gr jsp hot core bullet then order some more (same item number) and on the box it said 44 cal 240 gr jsp deep curl i also ordered 30-30 170gr fn deep curl i used them with hot core data, no pressure issues. but i think i have do more research on this thanks for the heads up

    OK. guys I did some checking. There are loads listed on the Speer web page for some calibers using the Deepcurl bullets. A few of the loads for the 30-30 170 grn were the same charge weight as data on the hogdon web page using the Sierra 170 grn bullet. When I checked some other calibers with bullets of similar design (flat base spire point ) in some cases the starting charge weight was HIGHER than the maximum load listed on the Speer web page for the Deepcurl bullet of the same weight. Judging from this observation I would say the Speer tech I talked to was on the level. If any of you guys are using the Deepcurl bullet please be careful and don't substitute load data from other bullet manufacturers as it appears that in some cases just the starting charge weight from another bullet could be over pressure when using the Speer Deepcurl even in the same bullet weight.

    I really liked the 200gr 44 cal one in my 44-40. Killed a few deer with them and they performed as advertised.

    Been talk around about the newer jackets and coating, really messing with pressures. But anyone that starts with a top of the book load, on any un tried bullet, is looking to get the horn, rather than the bull in the first place.

    I would be very surprised, if a great reduction will be called for, even after they are tested. Guns do not blow up for a grain over using the correct powder for the powders sake alone. The blow up for stacking of tolerances, lets say thick neck, cases too long, then perhaps a funky piece of soft brass, and then going a grain over all in combination. And even then, the gun rarely actually comes apart, though they may lock up tighter than the afore mentioned bulls butt in fly time.

    Generally, when guns actually come apart, its because the totally wrong powder got used, or the guy went several grains over, etc etc. If reloading in general was half as dangerous as some claim it too be, guys would not do it. All one has to do, is use some common sense, stick exactly by the book and they are as safe as any factory load.

    Does it occur to those that believe that the grass is always greener on the other side of the fence, may be because that guy takes the time to take care of his grass?
