Bump for interested parties. LOLWent to the range last week and continued working with rooterpigs new 230 grain bullet. In my SG 35 rifle and at the shorter COL I was running 2589 fps....with a longer COL 2600+ fps and 3500 ft lbs or so would be the norm. So, at the top end this bullet would exceed 358 Win and 350 Rem Mag power and enter 35 Whelen territory.........but I try to be sensible from time to time.
For most if not all North American large game that bullet producing 3000 ft lbs would be superb. The Hornady HITS calculator gives this bullet in that power range a LG rating past 250 yards, and a Medium game rating at 300 yards. This requires a minimum of 2425 fps for 3002 ft lbs. From earlier tests I achieved good accuracy around the 2450 fps mark, and now I am going to get serious about producing a tack driving, light (for an SG 35), hunting load that will produce 3000+ ft lbs. I am going to switch over to Grumpas 308-35 Rem cases, and will need to develop a 2450 fps load using them (the powder capacity difference of OEM 35 Rem cases and the 308-35 Rem cases necessitates doing so)....so I will be starting from scratch with the 308-35 Rem cases.
Even though the SG 35 can produce big numbers, I have found that a tad over the 3000 ft lb mark regardless of bullet weight is very comfortable to shoot in my 7 1/2 lb rifle, and I can save a little powder by using these powder puff loads. For my hunting requirements this is a win/win situation, and it gives me solid 350 Rem Mag power with rooterpigs 230 grain bullet.
My first range session will be all about velocity and finding a powder charge that will give me the velocity range that I am looking for.....I will also penetration test my 75/25 WQ expanding alloy with this bullet at the 2450 fps mark to see how it holds up to abuse. What I am hoping for is a nice expanding bullet for medium sized game, that can deliver in the power range that I stated above. Should be a real deer ( or anything else for that matter) slayer.
As always there will be more to come.......and, thanks again rooterpig for a superb bullet that is really showing great promise!!!
