So we've had all the 308 short barrel loads, how about the short 7mm08 loads?
I'm about to head down this path and thought I'd ask how others had got on? Thinking about going to 15 inches, so I can keep the standard Tikka stock intact.
Projectile will likely be the 162 ELD-X at this stage.
If you're planning to run a DPT can, you'll need basically 16" to clear the forend.
CFE223 will give good vels with a 120 TTSX in such a barrel. Still plenty of killing power out to a solid 300yds.
Mine ran well with 150gn eldx and 2208 at 15" outta a model 7 action
ADI pistol data is taken from a 15" barrel:

Sorry mine was 17" not 15 as earlier stated but yeah was a deadly load still :cool:Quote:

Ah yes powders on hand are 2208, IMR 4895, IMR 4064, 2206h, w760. Everything I don't already have in the cupboard is fairy dust at this stage I believe :ORLY:
I'm having a bit of success with the IMR 4895 and 162 ELD-X at the current length so hopefully that'll work when it gets shorter :D
Thanks @Steelisreal hodgdon have a pistol section as well and my Lyman manual has a pistol section with rifle cartridges listed as well, curious as to real world experience.
My loads for 16inch Kimber are
Factory 139 Whitetail is 2450
Factory 139 Superperformance SST is 2750fps
120 Ballistic Tip with 45gn 2208 is 2830fps
Tried 120 Ballistic Tip with 50gr 760 and got 2700
I loaded 2206h and 162eldx. Was a hot load but fast from an 18" barrel and quite accurate. Wont post the load publicly as only takes 1 Muppet to go straight to it without working up. Pm me if you want it
162 amax with rl17 from a 17" tikka at 2530fps. Pretty warm but comfortable as
Not sure what the point is trying to run a long/ heavy for calibre bullet out of such a short barrel, slower MV means worse BC.
Better to push something that's a bit shorter a lot harder and faster ;)
Makes it an all rounder. A 162 amax doing 2500-2600 from a short 708 is lethal up close and out to 500~ depending on the shooter. A little barnes or soft point will go faster up close but be out of steam a lot closer.Quote:

Used ADI pistol data for reasons stated above due to barrel length.
If you're going from a shorter barrel there's 2 theories: 1) send a light for calibre projectile and drive it as fast as you can like a Barnes or 120gr NBT. Usually of stouter construction.
Or option 2) push a heavier weighted match style bullet slower that opens up across the velocity range no worries. I generally aspire to the latter for both 308 and 7mm08. They both work. Keep it as simple as I can seems to be a oxymoron for a reloader but I've found that that is not far off the money.
Hope this info helps
18inch m700
150eldx at 2600fps
120 sierra game kings at 2800fps
Both using 2206h powder and seem to go good
Jeez that superformance really is something else isn't it?Quote:

Yeah same reasons @superdiver said, also I don't have any light bullets and now is not the time to go shopping for bullets :ORLY:Quote:

Twist rate is 9.5 so should be fast enough to make the most of the high bc but I'm more thinking about the bullet construction than that, big tip and hollow.point for expansion, good penetration etc.
120bt / 2206h is my favorite because i can get the speed back up there.
But really anything goes.
Ive tryed cheapo speer, seirra gk, hornaday sst, RN, eldx
Factory remington, federal blue, even S&b and PPU.
All kills outa the 16inch barrel at <300y
I've run 139gn SSTs, 150gn ELDx and now settled on 162gn ELDMs @ 2630 (20"barrel) only taken a couple of stags with it so far but been pretty impressive. Last at 380yrds was poleaxed on the spot. According to the ballistics calcs it's got horsepower to further than I'll likely shoot. Wind calls will be the biggest challenge.
I run an 18 inch model 7 in 708 with a gunworks can
139sst with 42gr 2206 in Norma brass and federal primers
Goes well
120 gr Barnes . 45 gr of 2208 from a 17" barrel . Getting 2775 fps. Zerod at 200 m, 2.5 inches high at 100. Click in 3 Moa and bang on at 300.
2206. 18" 3k with 120 Sierra and NBT. Primo accuracy.
Run the numbers on a 162 eldm at 2500 fps vs a 120 NBT at 3000fps. A short barrel doesn’t necessarily make lighter pills run better, they both lose the same amount of performance by shortening the barrel. Pros and cons to both just depends what you’re wanting to achieve.Quote:

I also have a Kimber Montana 20 inch with DPT but I use 120 gr sierras with AR2206H which has been good out to 400 mtrs
I never chrono’d either load as accuracy was what I chased.
Another good projectile is the 120 gr ballistic tip or the 120 gr Speer
Norma are claiming to make rounds optimised for short barreled, supressed rifles: https://www.norma-ammunition.com/en-...ilencer-series
Doubt they have any special voodoo in them but suspect they are running double based high energy powders (like Viht N5xx series and simillar).
Half case fills so they burn up all the powder before the suppressor :XD:Quote:
