Dave ....I tried 58 after being successful with 70 grn nosler varmints ...58's didn't group well at all for me and was fussy so I wish you well my friend

Just an up date on this.

Been out today and fired one Hornady superformance factory 58g v-max, and one 48gn home loaded hornady 58g v-max.
The reasoning here was to test my "ants" 300mmx11mm weaver rail drill for the Tikka action myself, im pleased to say its only 4 numbers out of centre on height, and 7 numbers to the right (Drone Pro 10x ), the 48gn home load was well under maximum load, and its was quite near the hole made by the factory load -------so with some tweaking its looking good.

With my home drilled weaver rail now being ok, ive loctited it on the rifle.
Next outing will be zeroing and load development.

Thanks to all your help on this thread Dave (warbucks)

Sounds like good results but a contrary voice if I may?

I would use a faster burning powder.

I use 45.5 grains of H4895 under a 55 grain BT in my 243 and get 4025 fps.

I also use a ASE SL5i moderator and can see the muzzle flash under NV.

With 48 grains of a slower powder, resulting in a MV of 3500, I am guessing the load is lower pressure and there will be more unburnt powder coming out of the muzzle than with my load.

Are you seeing this flash with your mod and under your NV?

Thanks for this, this is some very good information that i wished id known about before buying the tub of Ramshot hunter, i suppose the trouble is its on the banned list isnt it ?.
At the moment i havent shot it with the n/v but i suspect you will be right about muzzle flash.

What length is your barrel to get 4025fps with 45.5 gn of H4895 with 55g bt's -------might see if i can get hold of some H4895.
What would be the suggested gn of H4895 for the Hornady 58g v-max.

Thanks Dave (warbucks)

22" mate, but I think I have a fast barrel as Charlts on here couldn't crack 4000 fps with accuracy from his 243.

I don't think the powder needs to be H4895 specifically, just look for a powder that gives maximum velocity with around 40-45 grains of powder. I noticed this issue when developing a load with 55 grain ballistic tips for a friend of Adamant's with RL 17, another slow powder for this use, and using 49 grains of powder for around 3800fps. Hell of a muzzle flash but that may have been just due to the design of the Hardy moderator he used, by all means try your load under NV before changing.

I plan on using N140 after my stock of 4895 runs out but from my experiments will lose around 150-200 fps velocity, not that this makes much difference in this case as we are talking about around 5%.

Load data for your bullet here: http://www.hodgdonreloading.com/data/rifle

Max load is 43, bear in mind I am one grain over max in my rifle with 45.5 using a slightly lighter bullet, keeping a close eye on the chronograph and with what I call my "pressure shakedown test" which is loading a single case with the same load over and over again on the firing line until I see loose primer pockets. With Geco brass I tested this load ten times with a minimum batch capacity case and found no evidence of primer pocket loosening over that ten and so I think it's safe in my rifle, it may not be in yours.

What other powders do you have?

[warbucks]

N120 that ive been using for 53g v-max in 223.

Not with my old barrel, but new slow twist long bad boy is over 4100fps with very good accuracy. That's using a stout charge of RS60 if that helps the OP? Obviously it's quite an aggressive powder but my thoughts on barrel life are well known
