Today's Load Testing - Vhit 135

[bullbarrel]

I'm sure this is a daft question but you are cleaning the rifle thoroughly after each session (not group) and not just using a pull through or some such?

Are you using the rifle for target or foxes? If foxes then all those shot today will kill it.

Yeah, it always gets a proper clean with solvent and patches after every session. The rifle is used mainly for longer range vermin bashing and long range plinking

might be a daft question but if you have used the n133 with success, why switch to another powder.....ive just done my 53`s with n133. >HERE<

Nice group and you must be nearing max pressure with that load. Only switched because they didn't have any in stock and there was a 1kg tub on offer for £50. Thought it was worth a punt!

Here's the video clip of the COAL test using 25.1gr of Vhit 135: https://youtu.be/vYOVOsrZikA

I had no pressure signs at the time but wondered later when it gets warmer it might push it to top. I could always try extending the COAL this would reduce pressure and might tighten it up..(grouping that is)

Vhit 135 is apparently lower pressure at the same velocity. Might be worth considering

Pity you wasn't closer I could have swapped you some and tested it..

Have you tried vit 140, I use it in .223 and get very tight groups, it also meters very well

No I haven't, to be honest I was reluctant to try Vhit 135 having found a good load with 133. Sometimes you can play about far too much! Nice to know that other powders work though and have a few recipes to hand

[neutron_bomb]

For what its worth my best 5 shot group at 50 metres was 0.22 inches that was using 24.0 gn of vit140 behind a 69 gn sierra match king.
I have had similar results with cfe 223 same load and head.

Like Varget Vit 140 is an excellent powder in mid size cases with similar capacities to 308, it has its uses in smaller capacity cases where the bullet weight is approaching the upper limit for the cartridge but there are better suited burning rate powders for the 223, Vit 133 being one of the best.

For bullets under 55 gr n140 is a bit slow, though kenny gets good results with it and 55s. When you make it down for a shoot with the club I can give a bit of N140 to try for curiosity's Sake.

Mind you I use 39 gr under a 100 gr a-max in a 6.5 x 55 case that will hold 50 gr of N160, (n140 is really too fast for this cartridge) terrible case fill but still shoots 1/2-3/4" at 100. Could probably tighten that up a bit by playing with COAL but as this is a short to mid range target load (<600 yards) that's good enough for me

[neutron_bomb]

I dont disagree with you and I did specify 69 gn head, it may be less consitent with a lighter head, however my rem 700 has 1 in 9 twist and seems to prefer the 69 gn. It does not group well with 55 gn heads.
