Foxhunter,
Like I said in one of my postings. Most WILL experience bullet blow up when shooting bullets made from J-4 jackets. That is provided you drive the fast. I believe the Hammett bullets are made from drawn jackets other than J-4. I have been using the regular 30gr berger and shoot them at 3750fps. Only had a couple not make it to the target (just recently and only after not cleaning for about 40 shots). The Starke bullets are also made with J-4 jackets.Corbin

The only way I got around this problem when loading for fast shooting,(over 4400 fps) was to go to solids. Fred Smith of Bullberry fame, used to make some real nice 25 Gr lead /Copper alloy solids. I would Hollowpoint these and they wound up at 23grs, and I have used these up to 5580fps, with no problems. I haven't seen Fred advertising these for some time, but you might send him a note and see. I still have a Hundred of these left, if you would like to try a few.

Berger MEF and non MEF both will fail if pushed to fast. Some will reach the 100 yard target but few make it to the 500 yard target. The Hammett 30 grain bullets I have are made with J-4 jackets but will almost always make the 500 yard target. I think it has something to do with overall bullet design, not necessarily just the jacket. A bullet that will stand a lot of velocity is the old Remington 25 grain. I also have some custom 25 grain bullets made on some thick jackets that will stay together but they tend to foul, when pushed over 4000 fps. As Benny said the only sure way a bullet will stay together is to use the homogenous solids. As each rifle tends to be an individual use what works, in your case the Hammett bullets.

contacted hammett he said he uses the same jackets as berger,the differance is he uses a harder core. the bergers are literaly twisting them selves in two. i found front half of one of the bullits yhat seperated,it looked like a small missle nose cone. i suppose i will religate these bullit down to my 17 ah. they shoot real well at 3300 fps. foxhunter

I've heard conflicting reports as to whether or not he's still in the business. Since you talked directly to him, maybe you know? Thanks.

nick i havn't shot any 30 gr 17 in over a year. that is when i talked to hammett. i don't know if he is still making bullits or not. i hope so since i am almost out. sometimes when you havr the kind of problems i was having you just have to step
away for a while. its time to get back into it again. i simply have been having to much fun with my mk4 and 17ah to deal with a 30 gr problem child.

I lost quite a few of the Old Rem 25grs at anything over about 4500 fps. I still have several unopened boxes of them that are about 10 yrs old. One thing to take into consideration is the twist of the barrel and the velocity at the muzzle, and the length of the barrel. Stop and figure the RPM of that little bullet leaving the barrel....It's awesome...And then if your barrel isn't real clean, one scratch on the Jacket and and you can expect to see that Puff of blue smoke 50 yds down the range. I build a rifle about 10 years ago, just to see what a .17 bullet would do. I got it up to over 5500 fps with a
23gr HP. I tried many different types before I found Fred's Solids. Benny

Did John Geiges build this rifle? It looks like it groups well. Are you using 25 or 30gr bullets and what case? Give me a rundown on the components Corbin

John Illum with Rampro built the gun. I bought the wood from Cecil Fredi in Las Vegas and sent it to John. I am using Win cases Fed 205M primers Berger 22 gr Match and Vihta Vuori N-120 powder I am loading 15 thousands into the lands. I get almost as good groups with Hornady 20 V-Max’s.

Looks great. What caliber is this? I really like the idea of the Rampro short action designed for the small cases. And for the price of them, you can't even get a Remington 700 trued.

17 Ack Bee and a switch barrel I will test this weekend in 218 Mashburn Bee. John is really a master.

Brooks,
Nice stick of lumber. Lets see a photo of the whole rifle.
Jim beat me to the punch. What caliber and twist and maker.
Contour.Are you using the 1.150" diameter action or the 1.350"? How does it group at DISTANCE 300+ yards? Glad to hear you are happy with your purchase. I have the itch to do something but cannot seem to be able to pinpoint exactly what I want to build.
Thoughts are
17 CCM
17 hornet
17 Javelina
17-222 short and improved
600 nitro on a falling block.

Haven't tried it at 300, will Sat. weather permitting. It is the 1.350 action in 17 Ack Bee with a switch barrel in 218 Mashburn Bee. I will have to test the twist but as I recall it is supposed to be 1 in 10, like all the barrels I order.
I have a 17 Squirrel, 2 each 17 ack Hornets, a 17 He Bee, a 17 Rem and this 17 Ack Bee. I have really looked at a Cooper in 17 CCM but all the ones I have found are the earlier guns and have a "funky" chamber that won't accept the new brass. Brass must be turned on a lathe. No way. I presently am looking at a switch barrel in 17 Mach IV with a 20 VarTarg and a 221 Fireball. Really like what I see in the 20 cal 37 grain bullets.
Later

How close are the two dimensionally? I'm thinking a Contender barrel that could fire both 17HMR and 17CCM (even if the Cooper case had to be modified slightly) could be lots of fun. Basically, you would have a CCM with the added option of reasonably priced factory-loaded ammo.

Not close enough to use one chamber for both. I have each of these cases/cartridges in my collection. I'll try to get a photo so that you can see them side-by-side.

Thanks, Jim, I'd appreciate the photo. I've got a CCM in my collection, but haven't gotten ahold of an HMR for comparison yet. Cannon
