Nice rifle and great piece of glass. What reticle did you choose? Is that the standard rail mount for Swinglock? I have never seen that one before; keep in mind I have never seen them except in pictures. Yes I really like the mark 6 great glass for the price it has tmr reticle as for the mount I think the only thing he does not make is the barrel and stock blank

Yeah, the Mk6 is an awesome little optic. I shot some about a year back on LMT rifles at a training course. I have seen them on some guns at matches too; lost to one of those teams last year.

What temp and how long are you using to anneal the brass bullets?

What primer type? What powder? (you don't have to give the amount) Thanks

Not trying to rob any secrets but I am running a cut down hornet module on my current build... are they converted to LRP? Just curious and you don't have to reply if you would rather not.
nice shooting and nice gun BTW.

I think the swinglocks also have a small charge of powder in a crimped hornet blank. Could be wrong as funds won't allow me to see one up close!

OK, so the SMRP has a booster powder built right into the module? Frickin' genius!
Are there any LMRP Swinglock guns? Do they use a booster load in the module too?
How about the 209 primered Swinglock guns? Do they use a module that the 209 primer fits into that has a built in booster powder?
Or are the 209 Swinglock guns non-boosted?
Thanks

It's running SMRP and 10 gains of powder in module Well that should eliminate any ignition problems, that is a big advantage of a cartridge vs the unsupported 209 primers. edge. Someone is a faster typer

So much for the premise that single base loads are the point of the spear. Turns out the duplex is the tip of someone else's spear and that someone else is Tom Post. Just goes to show that there is never just ONE best method. There is always one right tool for the job. I knew there was a twist when he said Hornet based module and RL25 main charge. I have burned some RL25 over the years.

I do not mean to take anything away from guys like Richard who champion the duplex but I know all too well that unless you are a brand name like Hankins or Swinglock that too many are ready to dismiss your ideas as being a way around a problem opposed to a real solution. I'm glad to see that a guy who catches a lot of "poop" around here (I'm sure the site just auto-corrected that too "poop")around here and occasionally rubs folks the wrong way was just vindicated.

I've had great luck boosting the .416 loads. I've seen many ES's in the single digits using boosters with Retumbo. Plus it gives it the pressure it's looking for, to perform better.
That's a beauty of a gun kash913!

What temp and how long are you using to anneal the brass bullets? heat them to start glowing red no science to it go thru die like butter.

Thanks. I thought they took quite a bit more heat than copper but wasn't sure.

Great post and nice pics kash913! I had no idea a Swing-Lock would go so well with a pool. My wife says I can take the range and she'll take the pool...I agree! Also appreciate / like everyone else's comments as usual.
Those are some nice looking bullets from Lehigh and it's for sure we all look forward to hearing how they shoot.
Earnhardt, to answer your questions, there are only (2) priming systems used in Swing-Lock rifles. First is the 209 primer and second the pre-loaded hornet primer module. Most rifles use 209 primer ignition which does not utilize any type of module or preload booster charge although some duplex load data is used in some rifles which can be very similar to loads used as mentioned on this board. Some testing was done a long time ago using LRPs but with no advantage experienced. Except for large chamber rifles, Swing-Locks do well with 209s because the primers are almost 100% supported which helps assure the best possible seal and enables the primer to support higher pressures which in-turn allows the use of larger diameter orifices for better efficiency of ignition.
As kash913 said, the hornet priming module uses a small rifle primer and is pre-loaded with a small charge of a "specific" type of smokeless powder. The hornet case is not a stock case but is radically modified with a bullet press using a series of specially designed dies to produce the module which fits into the Swing-Lock system. That priming system is high out-put for efficient large powder volume chamber ignition where loading density is typically under 100%, it is very clean with very low maintenance, gives excellent seal, can withstand very high pressure, the modules are easy to load and are used over and over...can't say I've ever worn one out yet.
To go off on a slight tangent regarding having some custom bullets made and another new big chamber Swing-Lock Long Range rifle; recently Cutting Edge made me some 550gr .458 dia. MTH bullets with estimated .800 B.C. which shoot very well from the new .458 long range rifle. The new rifle with 26In. barrel puts the bullets out at over 2600 fps and just for giggles puts out a 250 gr Hornady MonoFlex bullet at almost 3700 fps. Thats a 26 In barrel. Out of my 34 In.barrel test rifle the 550 gr goes out at over 2750 fps and again for giggles the 250 gr MonoFlex goes out at over 4045 fps both with surprising accuracy. Velocities were measured using both MagnetoSpeed and Pro-Chrono with infrared lighting.
If anyone wants some .458, 550 gr CE MTH bullets to try I am selling them for $115.00 / 50 pcs. I do realize that is a very heavy bullet for most and a fast max. 15 In. twist is needed to stabilize. The Swing-Lock rifle uses a 14" twist.

4045 fps out of a 458?!!! 2750 fps with a 550 grain bullet?!! I'll drink to that! That's wicked! Need a racing helmet/harness to keep your head from snapping back from the recoil? Thanks for the info Tom! It greatly appreciated!

Maybe build one of Those 458 with a 40 inch barrel we could get that 550 gr up to 3000 fps?

and again for giggles the 250 gr MonoFlex goes out at over 4045 fps both with surprising accuracy. .SNIP. Do you mind sharing the load, obviously with all of the usual disclaimers If not in public I would appreciate the load in a PM just to compare with predicted velocities on my Powley and Quickload calculators. edge.

Edge, I would not share the load except to say it is a duplex not of the same structure as typically seen on this board and it is used in a large chamber design. With regards to pressure, it was tested in (2) different rifles showing pressure traces within limits considered acceptable and in fact lower than pressures observed with some other data from the same two rifles.
