Thread: .270 Projectiles Lagging Behind

Having found a 270 with a "buggered" barrel, that shoots very consistently around the moa mark with several different loads, I did a wee bit of load development at the weekend and loaded some 140 Interlocks. Pushed along by 58gn's of Superformance rather than the 4831/2213 I normally use. No surprises really, 3 shots under 28mm @ 100 metres. But it was doing 3062fps across the chrony, compared to just under 2900 using 4831. I dont normally chase speed, way overrated, but am happy to continue to load with Superformance if thats the result. And absolutely no pressure signs.

Have you tired the other powders in that rifle? It may just be a "fast" barrel.

I checked it first with 57gn's 4831 pushing along a 130SST, chrony averaged 2848fps. My records show that load was doing 2924fps in another rifle. The same records also tell me that at some point I had a load using Superformance and a 130SGK, and that went 3159fps! Both the 4831 load and the Superformance load were shot about 15 minutes apart, to let the barrel cool down.

My son and I have identical 308 Husky's, his will put 4 different loads in the same 25mm group at 100. We both use the same reloads for hunting, and his is 70fps faster than mine. Same rifle, same barrel length etc.

How far are you trying to shoot stuff? All those projectiles (and plenty more) provide more than enough oomph when launched at 270 speeds for a very long way out.

I like the sound of:

350 HPBT MATCHKING .805

Amaxs/eldm are softer and thousands of deer get shot every year with them. I'm running factory 130 gr superformance ssts going fairly quick through mine for the mean time until I get around to developing a different load.
I am currently on my best streak, 16 deer for 16 shots, no misses or follow up shots. Furthest was just under 500 yards. Couple of big post rut red stags this year over 100 kg. No problems.
I also chest shot a big bodied red stag last week with the .223, made it about 15 yards before tipping over.
Pretty simple really, if it's soft or lacks grunt avoid the main shoulder bone. Soft bullets have their upsides, more damage and reliably opening up at low velocities are big plusses depending on the type of hunting you do.
Shot placement is the key!

partitions cost more but they do what J.N. intended when he designed them...kill stuff deader than dead. if you already have a good sleak longrange load that is working for you.....why not just load up a bog std soft point or a partition for spook n shoot type hunting...it takes a couple of seconds to slip in sleak load if n when oppotunity arrises. the 130grn sst and the 130grn balistic tip both have bad reputation for OCCASIONALLY opening up too fast up close /at speed and loosing big animal...Ive shot quite a number of hinds with BTs and as long as I DID hit shoulder bones they went down fast...chest shot deer were dead on feet but didnt know it.
in 30 years of using the calibre only once has load let me down,and it was entirely my fault....wondered what a 110grn hp varmit load would be like on small fallow,,,and found out,,,,useless on shoulder shot,blew pudding bowl sized shallow crater,massive shock but no penertration,wouldve worked on neck,but not shoulder...mate did same on red hind and lost it.....use a good or heavy load please.....please learn from others mishaps and dont risk loosing that once in lifetime stag.
