Thanks Jimbires. The split chart for AR-Comp gives more choices for velocity and pressure , while burning 100% . I like this powder in every caliber I've tried it. I do respect that this powder can build pressure quickly , and will continue to work up slowly . The powder chart shows other...

The 53.0gr water capacity was FL sized . Fired case is 53.9gr . FC brass weighs 178gr , and is smaller capacity than may other brands. Chrony is set at 12 ft from the muzzle. JBM Ballistics calculates the correction to muzzle at 10f/s higher than stated above . AR-Comp is sensitive to case...

I have a Quickload request for a 7mm08 ; 22" BL ;Speer 130gr Hot Cor ( Flat Base) ; FC Brass (water capacity 53.0gr) ; Fed210 ; OAL = 2.857" (Jump = .015"). I did a firing test at 41.0gr AR-Comp , and got 2837f/s with ES = 6f/s . I was expecting 2887f/s like I got with 130gr Sie Pistol bullet...

Now that you have your QL answer , I will share my range experience from 2 years ago :Bolt action 7mm08 , 22"BL . I followed Alliant's Reloder 17 data as closely as possible : FC brass (178gr weight) ; Fed210 ; 46.0gr Re17 ; OAL 2.793" @ Jump .005" ; Speer145gr BTSP . 2834f/s w/ ES = 10f/s ...

I am requesting a QL powder profile for Reloder 17 (42 to 43.6gr in 0.2gr or .459% steps) . 26" BL , OAL= 2.694" @ Jump .010" ; Fed Premium Brass 52.8gr H2O capacity (they weigh 175gr) ; Fed210 primer. Hopefully one of the loads will reach 1.19ms BL time. The Hornady 87gr Vmax has a good BC that...

Thanks Dwh for the excellent info. That 43.6gr charge of AR-Comp is listed on Alliant for 155gr Horn. VMax . I thought the pressure would be similar for the 150gr SP , with it's flat base. Preacher : thanks for your stories about your rifle. Mine has sentimental value : it was my dad's deer...

I have a very fussy Model 100 Win. for port pressure only 9" from the bolt face. I am requesting a Quickload run for 2 powders : 45.7gr of TAC ; and 43.6gr AR-Comp, with 1% steps either side. Details :FC GM brass (overflow capacity fired 54.4gr H2O) ; 22" BL 150gr Horn. SP #3031; OAL 2.800" and...

Thanks Dwh for the latest QL run for 6 Creedmoor. Timing was perfect : I did not expect your answer until the weekend . Looks like Reloder 15 has a Node4 accuracy node around 39.5gr and 3236 f/s , which is perfect for impact velocity @ 87gr Vmax . Just like .243Win , Reloder 17 will drive it...

Thanks Dwh for your QL posts ! Many of us are sitting on the sidelines of a 6mm Creedmoor , and considering it in a future rifle. I just downloaded the Sierrra Load guide , and in a new pressure barrel , the velocities look very good for 24" . What is most impressive is the efficiency of the 30...

First of all , I do not own a Magnum caliber rifle. However , I did have lot of Fed210 primers that was not compatible with my lot of R-P brass in a new Savage Stryker pistol in 7mm08 ( Bolt action ) . My brass case head and bolt face was plasma etched similar to yours , but not quite as deep...

Many thanks Dwh for all the QL runs! Yesterday I bought some AR-Comp to try , as well as A2495, IMR4895 . I hope to have good weather for one range session between Apr. 10th and 15th . I will update this post at that time. Something else stood out in the last 60 VMax run :about 1.5 pages down...

Thanks Dwh.My observations of the data :there are no Accuracy Nodes above 55000psi and 26" Bl. For a given powder with 2 different case capacities ,Barrel Times are the same at the same pressure (and Not Velocity). Optimum Barrel Time for 26"Bl. is 1.106ms (or 1.102ms tweaked higher). The charge...

Thanks Dwh for running the QL simulation .When you have time , could you run it again on both bullets for water capacity of 30.53gr ? I only own the demo version of QL , but I do understand that the water capacity must be correct ( in my case for LC Brass) , or all pressures and velocities will...

I have a .223Rem Bolt action , 1 year old Shilen 26" Bl. , 1:8" twist; Wylde Chamber. I have been using IMR8208 with a Hornady 60gr VMax , 3150f/s . That load is over Hodgdon max. , but safe in my rifle when loaded to 2.254" COL ( around 5mils off the start of the throat ) . I am looking for...
