then i just tried some hybrid 100v since its loaded inside the 280 rem and also the pressures ended up reduced with fantastic velocity so I believed I'd strart low and see what happened.
Hybrid 100V is the result of combining the systems of spherical powders and extruded propellants. The chemistry of the spherical powder is coupled with the geometry of the extruded propellant, creating a easy-metering, super-shorter granule, extruded, formed propellant with higher Vitality.
I figured not far too enthusiastic about the 243. So what if the additional pace gets to the next precision node. May well extend my helpful assortment out a few yards...
I happen to be Performing up loads due to the fact Jan. a 12 months ago on the Kimber 84M in 257 Roberts and arrived upon 100V plus the promise of larger velocities at decreased pressures. I began to chrony the one grain previously mentioned min. as quoted during the Hodgdon guide. 1st two velocities were the place I expected them to become for every the book plus the 3rd was way too but I could not receive the bolt open up to avoid wasting my lifetime. I took the rifle property and took a scrap 2x2 and tapped the bolt up and then started to get it to move back when Abruptly the bolt pinged throughout the garage. Well now I was in deep schite. I boxed in up and despatched it to Kimber. I sure was not accomplishing anymore superior for it so despatched it towards the professionals.
I like it better than some other powder I've experimented with in my 257 Roberts rifles and it has become a favourite powder for my son in his 6mm Remington.
It really is a fascinating powder via the numbers, hybrid 100v powder reading Hodgy's common fluff i assumed it to be extruded. By MSDS it is a ball powder from GD's Florida plant. Tends to make me ponder how the BR is controlled.
I virtually set my chrony 15-20 ft before the muzzle then I understand I'm not getting any effects from muzzle blast. I go to a ballistic calc. and established that range up at the space of my chrony and get my legitimate muzzle vel.
My hundreds are quite steady across the chronograph, it's possible all will hold properly by means of taking pictures and looking, got a hundred of these loaded hybrid 100v and ready.
This spherical propellant is designed expressly for your three hundred Remington AAC Blackout cartridge and meters extremely accurately. CFE BLK incorporates our Copper Fouling Eraser ingredient, initially used in armed forces propellant, which enormously deters copper fouling and contributes to lengthier periods of top precision with considerably less barrel cleaning hodgdon hybrid 100v time.
I have run the loading sequence as a result of my brain quite a few instances, And that i have no fantastic explanation. 150grNBT
Actually just about anything more than 60 grains of powder Rewards from the usage of a magnum primer. I feel If the teams are very good in the 28-2900 mark and use among the list of loads you mentioned you will end up greater than pleased with the effectiveness of the Bergers on sport ! Understand that bullet is built to penetrate about two-three" in advance of it will it's career ! You should let's know regarding your accuracy With all the masses you mentioned?
Did anything very similar just lately. Labored up the load received to remarkable accuracy. Went to lunch. Came back again loaded several much more to double check the precision. The second one did not sound right And that i received a little blow back again. Had to conquer open the bolt as well as brass was however fused nto the end of your bolt.
My present-day load is quickly and exact even so the bolt carry continues to be more than what I would like and will most likely again down One more 50 % grain and check out.
I'm new to this forum and I have some information to share about my current encounter with this cartridge & powder combination.
