Maltby Project Update

[Mt203]

I haven't used 4895, but I use 3031 and 4064 with success. 3031 is weird in all of my Enfields as in the charge doesn't really change the point of impact or size of the group. I've had up to a 4 grain difference in charge and they are still landing in the same area, with the same size group (1.25"-1.5" in a mk3) 4064 I've done more testing in my LB No.4 mk1* with 2 groove. It likes the Sierra 180's and the Hornady 150's, the last batch I worked up were impacting 6" low at 100 but sub-moa. It is not bedded, but has a new forend that I fitted and I suspect that has a bit to do with it. So I guess what I am saying is my No.4 really likes 4064 and my No.1's really like 3031 and 4064 in that order.

Appreciate the information fellas. I do have some 4350 sitting on the shelf as well, just not a quantity. I was trying to utilize what I had ample stock of as most supplies here are difficult to come by presently. (Even Sheel’s in GFK has next to no supply of anything.) In a fit of desperation I ordered up Redgwell’s book off Amazon the other day. .303brit here just doesn’t have the following it deserves.

3031 is to hot for the 303. Light loads border on secondary explosion. It also tends to pressure spike quickly with temperature increases after load development temperature.

I use 46Gns AR2209 or 4350 in your land in all my 303's No.4's...

I do not think fast powders are the go with the 303's

Agreed, Ron. AR2208 and AR2209 are the 'go to' more relaxed burners than the rapid AR2206H.

Having serious consideration of the exercise, no one can reproduce the Mk VII round as a standard until they can use the open based, rear-weighted Mk VII bullet. And no one is or will be making them again.

So the best one can do is approximate.

The most important thing to do is match a tight recipe for each rifle. If you have 4 x .303's you will have 4 x 'standard' loads, if you're seeking a higher level of consistency and accuracy. If you're simply out for a hit and a giggle, then go with one load to suit all and be happy at 100 yards/metres.
