Range Report Ladder test result

[pitdog85]

hi guys would like some help with this ladder test. 139 scenars loaded at coal 2.840 10 thou off lands for my 6.5x47l. Loaded in .3 g increments from 38.2-40.6 of H4350

it looks like a node at 40g as shots 6,7,8 (39.7-40.3) had inch vertical at 300m. Also possible a node at shots 4,5,6 (39.1-39.7) had 1 and a quarter inch vertical.

however shots 7,8 and shots 4,5 had almost no vertical at all. Where should I go from here 40g seems pretty high I didn't really want to run it this hard there were no pressure signs but that seems pretty high compared to what others use. Was hoping to find a lower node. I'm think of doing another 300m ladder with 5 of 40g and 5 of 39.4 what do y'all think?

Load between 7 and 8 and shoot for groups at 300. You probably havn't maxed pressure out yet, I'd work on up to 41.4 grains after shooting a group at 300.

thanks mate I will load some up between 7&8 and re shoot what about 4&5 they were close as well? There were no pressure signs at 40.6 but I didn't think many went this high (41.4) with the 6.5x47L that's getting up there with creedmoor loads?

You would probably be surprised how many are loading 6.5 creed with 42-43g of H4350. It depends on the rifle chamber and brass.

hi lash yer I guess I thought there was a bit more difference between the 2. I remember reading the 6.5x47l cartridge guide by the 6.5 guys and they were talking max loads around 39.6 of H4350 with 139 scenars I was a bit surprised a people going up over 41g. My coal is right up there approaching those using 6.5 creedmoor so I can prolly get away with a hotter load. I was able to fit 43g H4350 in there with only a slightest crunch and that was without vibrating the case or pouring through a long tube etc that was just pouring straight in with a funnel. I didn't shoot it at 43g though just wanted to see how much I could get in with the 139 scenars, 42g had no crunch at all.

I've had as much as 44g+ in my .260 before seeing pressure signs, but 42ish grains or thereabouts is almost always a good node for .260. At least in my limited experience of just three different barrels/rifles.

He clearly states he's using a x47 and yall comment on your Creedmoor and 260 loads. Fukin shit man can yall read.

Yes, I'all can read just fine, which is why I responded to his post #3 wherein he commented that 41.4 was up there with creedmoor loads. So I responded with loads that are considered normal for creedmoor. I'm pretty sure that the OP knows what we were discussing. So, fukin shit man, don't fukin worry about it, ya know?
