Thread: Bullet speed?

Ive done a fair bit of reduced recoil load testing in '08 cases and in 223. H4895 (2206H) is well know that you can load down to 60% of a max charge for any cartridge that has data for that powder, however the accuracy (grouping is generally not that great).

IMR4198 is the powder that Remington use in their factory reduced recoil/Youth ammo. Ive tested both 2206h and IMR 4198 in reduced recoil load in various cartridges, 260 rem, 7mm08 and 223, and all of them shoot much much smaller groups with the IMR4198.

30-31gr of IMR 4198 in a 260 rem/7mm08/308 will work well with 120-130gr bullets.

14gr of 4198 behind a 55gr shoots tiny little groups in my 223.

I honestly wouldnt bother trying 2206h/H4895. Just buy IMR4198.

I do my full powerloads with2206h ,43g behind 150g Core-Lokt or interlocks ,not keen on buying different powders ,just gonna stick to the one fornow,also have trail boss and some 2205 pistol powder here left over over from the 44mag.

Fair enough, a reduced load of 2206H will work, just possibly not as accurately as IMR4198, but when limited to the short ranges of a reduced load it probably wont be a problem.

Just make sure the rifle has a can on it a mates 8 year old fired my 708 once did seem to bother him, got to watch they try to put their eye to the scope.

Yep got a can on the gun,bush hunting so anything around 2in @ 50m is good enough.rfeally trying to turn my .308 into a 7.62x39..

just load up some start level loads and see what they go like....no need to overcomplicate it.

yep, I'm trying to turn my 7mm08 into a 7-30waters

Decided on 38g 2206h,will see how they go on the weekend.

Going for the best accuracy in my opinion is fine but not really needed here. If the shots all go into 2 to 3 inches at 100 yards it will be fine for a bush spook n shoot rifle.
More inaccuracy is introduced by the shooter waving about when taking a standing shot than comes from the bullet. If your are moving a couple of inches in the aim a 1/4 moa rifle won't be better than one that shoots 2 1/2 inches fact the less accurate round may sometimes actually help by countering some of the shooter error.
Anyhow even at 200 yards the cone of error is still about the size of the kill zone on medium sized game, just don't try head or neck shots.

Never shot a deer over 80m away so shouldn’t be a problem..no chrono so speed will be a guess..my sako has never shot a load over 2in @ 100m no matter what I throw down the tube ,she is pretty forgiving in that regard luckily.

For reduced 308 loads you could just look at 307 Winchester and use those , if you want ?.

How did they go?

Ive been shooting a reduced load in my 30-30 Ruger #1,
125 Ballistic tip with 35gr IMR30-31, gives me 2500fps, 20 inch barrel,
Shoots well and nice light recoil.
You can look at reloading data, for single shot pistols, if what you have doesn't work out.

2500 is a reduced load in a 30-30?
Makes my 1800fps when working up a full power load look pretty anaemic. 16 inch barrel though.
